Włoch pokazał kolbę jak wygląda gotowa, czekam kiedy dostanę.
Dlaczego zamieniles szyne z 20moa na 25 moa (tok myslenia)?
Mam akcje Barnard model P, dotychczas miałem w nim zamocowaną lufę w kalibrze 308Win.
Dostałem zamek magnum do tego systemu, wraz z lufami w kalibrze 300WSM (nie kupowałem systemu ani nowej broni bo mam ich już i tak dużo).
Do tej akcji miałem kolbę Dolphina ALU (nie lubię jej) oraz moją którą używałem ale montaż odbywa się przez BarrelBlok.
Kłopot polega na tym że jak chcę przetestować jakąś nową lufę, to jest to duży kłopot z uwagi na BarrelBlok. Tak jak wspomniałem, mogę użyć kolby Dolphina ale delikatnie mówiąc jest słaba.
Z tą kolbą, będę mógł testować różne lufy które mam do tej akcji, bezproblemowo. Dodatkowo chciałem mieć do 300WSM R.A.D. to również sprawdzę jak działa.
Wymieniłem ostatnio szynę w tym systemie z 20MOA na 25MOA, będzie teraz bardziej uniwersalna 😃.
Nic tylko strzelać pozostaje, bo jak już niejednokrotnie wspominano, Trening Czyni Mistrza. Tylko czemu, wszystko jest takie drogie 😭.
A jak wszystko będzie dobrze, to wtedy zamocuje całość w tej kolbie z której strzelam, bo jest cudowna, nawet już mam jak do niej R.A.D. zamocować 😁.
Tak pisałem kolegą, a dokładniejsze wytłumaczenie ostatni LongShot odległość 1105 metrów właśnie kaliber 308Win. Akurat na takich zawodach strzelam trzema rodzajami amunicji.
Kiedy z czego strzelam zależy od nastroju i w danym momencie upodobania. W 308Win strzelam z ELD-M 225gr i ELD-M 208gr oraz z 200gr Berger Hybrid Target.
Przy tych warunkach pogodowych strzelając z Bergera 200gr wyszło mi przewyższenie 44 7/8 MOA. Luneta wyzerowana na 100m, March czyli zakres elewacji 60 MOA.
Ustawiając przewyższenie zobaczyłem że przekręcić w lunecie mogłem na wartość 44 6/8 MOA.
Zaokrąglając to do 45MOA wychodziło że zerując na 100m miałem 15MOA Down i 45MOA UP. Dostałem szynę z pochyleniem 30MOA ale postanowiłem dać pośrednią jako bardziej uniwersalna dla mnie.
Teoretycznie teraz mam 10MOA Down i 50MOA UP.
Dla ELD-M 208gr ustawienie na 100m mam około 2 4/8MOA Down (w stosunku do Bergera 200gr) i przewyższenie na 1105 metrów około 40MOA. A więc jak strzelałem z tego pocisku to nie zauważałem problemu.
Jat strzelałem ostatnio z Bergera 200gr to zobaczyłem problemik który mnie denerwował.
Ta szyna będzie tak jak wspomniałem dla mnie bardziej uniwersalnym (lepszym) rozwiązaniem.
Jak wybierzesz wage naboji (tok myslenia)?
Programy balistyczne swoje a życie swoje.
Wszyscy którzy od wielu lat stosują 300WSM, podkreślają że jak strzelają przykładowo 1000y to, mniej ich zaskakuje zmiana wiatru jak stosują Bergera 230gr.
Podają przykłady że koledzy strzelający Bergerem 200gr czy 215 gr wylatują za linie 10 a oni ciągle pozostają w polu 10.
Jak to określaja strzelając Bergerem 230gr maja mniejsze zaskoczenie oglądając swoja tarczę.
Jak wybierzesz dlugosc "freebore" (tok myslenia)?
Do tego kalibru przygotowania robiłem dość dawno, bo rozwiertaki były zamawiane w 2017 roku, nie pamiętam już wszystkich założeń, oczywiści powoli wrócę do nich.
może to ci pomoże. We wszystkich lufach mam tak samo. Co nie zmienia faktu że mogę sobie freebore poprawić jak uznam za stosowne.
Rusznikarz nie oddał mi jeszcze rozwiertaków i wzorników bo ma koledze jeszcze dorobić lufy a innemu pożyczyłem Redding Inctant Indicator tu też jest jeden wzornik
wychodzi że na razie zanim mi nie zwrócą jestem goły i wesoły. Zrobię łuskę wzorcową ale na początku chciałem ją odpowiednio sformatować i wraca w/w info nie mam wzorników (Go Gate).
Poczekam aż mi zwrócą moje rzeczy, nie spieszy sie bo jeszcze kolby też nie mam a przyjdzie do niej bedding zrobić jeszcze.
Do jakiego rodzaju sportu ten karabin?
To co strzelam zwykle Fclass jak również inne zawody długodystansowe.
Dlugosc luf?
Jedna skok 9 długość 816mm czyli około 32", inne skok 10 763mm / 30"
Jaka osada pocisku w lusce (np: ogon pocisku wyżej niż "donats")?
w łuskach normy w tym kalibrze donats nie powinien wystapić, ogon pocisku raczej juz delikatnie w ramionach ale
sprawdzę ile proszku mi wchodzi i jak powinienem osadzac zeby mieć odpowiednia pojemność łuski.
Sprawdze to jak bedę robił pierwsze pomiary i amo na próby.
Na pewno założę około 880-900m/s dla pocisku 215gr a 860-880m/s dla 230gr
Zobaczę co i jaka prędkość jestem teraz w stanie osiagnąć dla RS76, Normy i VV przy pociku 215gr
Po jednej sztuce i będe wiedział co i jak mam.
To są moje różne zapiski jakie sobie robię od paru lat - zdjęć nie będzie widać ale są jakieś poglądowe infa

Match .300 WSM Load — Berger Bullets, Norma Brass, H4350, Fed 210M
I run the .30 Cal Berger 215gr Hybrid bullet exclusively.
I have not found a better long range bullet for F-Class.
I use neck-turned Norma .300 WSM brass, H4350 powder, and Federal 210gm match primers.
I anneal the Norma brass with an AMP 2 annealer every firing.
But I do NOT trim and chamfer after every firing — only when the brass gets to the point of requiring it.
For the 215 Hybrid I've run 66.7 gr. of H-4831sc in a 32" Krieger 5R 1-10" (1.450 straight in barrel block on a Maxi-Tracker BAT model "M").
Norma Brass, Fed 210M, Barrel has a 0.285 Lead, Bullets were 0.012 Off the lands. Velocity was at 2957 fps and I consider this as a max load for my gun, in fact I've dropped it back .2 of a grain. - No leaking at primers but I could "feel" that they weren't as tight as on the previous loading. - Brass is neck-turned for a 0.014 neck thickness running in a 0.3395 neck chamber. - 5 shot group @ 300 yards was in the .3 range with hardly any vertical. (and I had 5-7 mph wind). - Of course you'll need to "tune" for your gun. - I'd start at 64.5 and work up.
215s and H4831sc using Fed 210 primers.
this time from 65.3 to 66.2grs. At 65.3 we were at 2870 and up at 66.2 we were near 2950.
2910f.p.s. with the 215 Hybrids
The TOP wind defying bullet is the Berger 195 running out of the SAUM at 2885 or so. But the 215s at 2910 or so comes pretty dang close.
need to keep the 230’s under 2865fps and 215’s below about 2960fps to comply with ME limits, it would seem most do not shoot these bullets above these speeds so I should be okay
I am playing with a new WSM (I have had many many of them)
I have used Berger 190's, 200 hybrids, 210's, 215's, and 230's all in berger
I have used JLK 210's and Sierra 210's
I have also used Amax 208 and the new ELDM 208's
And a few others that didn't do anything for me right away. Now I have tried all these not in the same guns so it's not a factual comparison of any kind just general experiences that I have had.
-Best 100 yard groups ever I got with the 208 Amax
-Best 1000 yard setup I ever had was the 200 grain hybrids (set the record at Ridgway with them)
-Best over 1000 yard groups was the 230's
-The best over all consistent from 100 yards - 1 mile was the 208 Amax (I believe some of that was that they liked to be pushed a little faster than the bergers)
Running 210's from 2850-2875 area barrel life is longer. I don't know what your load is but that has been my experience and it shoots.
I do find the WSM will run nice at 3025fps with a 208/210. Yes we all know they will shoot lights out in the 2800's but it gets touch and go til over 3000fps. The only issue I have found with running them that fast is it's much harder on brass and the recoil gets a little punchy.
My "original" load WAS with H4350. It was 61.3grs. The velocity WAS 2930. That was Spring, Summer and early Fall. However, a couple of weeks ago I shot the Arizona State Mid-Range Championship. I loaded up 200 rounds for the 2 day event. The previous Monday, I took the rifle out to "foul-out" the barrel and make sure it was sighted-in. To my chagrin I was shocked to see that the velocity fell to 2890! That is a 40f.p.s. drop! Since it was the same lot of powder, I can ONLY assume that the "cooler", NOT COLD, temps caused the drop. To me, that is not "temperature stability". I know from LOTS of experience that the NEW RL-Powders, RL-16 and RL-23 can go from winter thru summer to winter again with no appreciable loss / gain in velocity. So I took it out and now I wish I would have started with it. My charge weight is 62.7grs. The accuracy is either the equal or the better of H4350, certainly the accuracy node is higher!
I use 61.3grs of H4350 and have them seated 18 thousandths OFF the lands
In a 30" Broughton 5C with H-4350 I'm running at 2910 fps @ sea-level running 210's in a Light-Class gun
In a 32" Krieger 5R with H-4831 ssc I'm running at 2967 fps @ sea-level running 215's in a Heavy-Class gun
The 2nd BAT 3LL is under construction and will be a Hvy-class gun set-up to run 230's in a 32" Krieger 5R. - I'll let the target tell me what load to run. - I plan to start load development using RL-23 & H-4831 ssc
traight from the BIB website & I'd say Randy knows something about bullets & stability rates. twist rates which impart between 1.4 and 1.9 Sg will provide the best precision. While faster/slower twist rates may work well enough, twist rates which produce Sg outside this window begin to errode potential precision.
.300 WSM Load Details — H4350 with Berger 215gr Hybrids
Gary was shooting pointed Berger 215gr Hybrid bullets in Norma .300 WSM cartridge brass. The powder was Hodgdon H4350 with Muron KVB7 primers. Gary say his load runs around 2850 fps, and is very accurate. To demonstrate, here is a three-round, 100-yard test target, with a group measuring in the ones. Pretty impressive for a big bullet and a short magnum cartridge.
What is wrong with H4350 ?
Great for 200 & 210's, should work with the 215's as well. - I tried H4831 ssc and haven't tried H4350 yet with the 215
WSM, 66gr of 2213SC have me 2915fps
Yes Sir Norm! I made up 2 / .300WSMs.. One that you read about, shooting the 215s and another I just did shooting the 200-20x pills. Those 200 grainers screaming out of the barrel at 2930 are a formidable projectile! We had some very bad fishtailing winds and those large pills helped me stay in the 10 and X ring!
ook my new to me WSM barrel out today just to test for pressure.
Loaded the 215 with a 0.020jump and used AR2213SC for powder.
Starting at 62gr I just fired incrementally higher charges to 66gr
This barrel is only 30” long and 66.0gr gave me 2870fps
There is absolutely no sign of pressure so I will work a little higher next time I’m out and see if the 2910fps node is there with my rifle.
Just for fun I fired the last 6 incremental charges (63.5 to 66gr) at the same target for a 0.25” group.
It’s only 100yards, but the barrel looks to be a goodun.
Was also doing a similar test with a SAUM barrel on the same rifle. The WSM felt like a big push (similar to a 284 but a bigger push) whereas the SAUM felt sharper in recoil. (Using 2209/H4350 in the SAUM)
Admittedly the WSM is not right up to speed, but it certainly wasn’t too unruly, it’s also lighter than the SAUM both being nearly 400grams underweight for F-open

I initially used IMR 7828 SSC in my .300 WSM with 34" barrel and 230 Hybrids. The load produced ~2950 fps and was very precise. Unfortunately, I could not manage bag handling, no matter how many tricks. Dropping to H4831SC produced ~2865 fps, similar precision, a broad .8 grain window, and barely manageable bag characteristics. My .300 WSM is a BAT 3LL in Manners carbon fiber stock and weighs 21# 14oz. (9.92 kilos for the Imperially challenged)
Allegedly Re23 (alongside AR-Comp and Re16 the new-generation Bofors manufactured Alliant powders) is temperature insensitive thanks to 'TX Technology'.
We're only just starting to get these grades into the UK, no chance to look at them yet. I wonder too how much nitroglycerin is in the new grades as it varies considerably between the older members of the Bofors manufactured Norma / Alliant families. Some have less than 5% by weight, but Norma 203-B / Re15 is listed as 7.5% and MRP (very close to Re22 if not the same thing) at 11.5%.
I am running 65.7grs of H4831sc to get to the 2910 node, with the 215s. My guess would be somewhere between 63.8 and 64.7 of the RL-23.

Shiraz: I use Norma brass with turned necks. At the Berger SW Nationals I used Berger 215gr Hybrids, Fed 215 LR magnum primers, and a stout load of Hodgdon H4831 SC. This drives the 215s at around 2910 FPS. If that sounds fast, remember I’m using a a 32″-long barrel.
Shiraz: On the .300” WSM
a tight-neck .336” chamber for turned necks. Basically, I fire-form all my brass in a fire-form barrel and save the good barrels for matches. Gordy is so good that he can chamber different barrels to within .0002” in the headspace dimension. That way I can have several same-caliber barrels and can use the same brass for all those barrels. I use a .0005″ shoulder bump for my brass. I load the bullets so that the bearing surface sits above the doughnut ring.

I have 8 firing on 300 pieces of Norma 300wsm brass. Primers pockets are still tight. I run 230's at 2820fps in F-class
Have tried the 215's with H4831SC & they shot very well. - Managed 2967 fps but I can tell that this is the upper node & the brass will probably only make 3-4 loadings in the barrel (5R Krieger) that I've tested them in.
