.300 Varminter

Well I have been a troller for quite a while now so I figure I'll contribute something.I put this together for strictly nuking coyotes


I built a .300 WSM on a Savage 12fvss. The barrel is a Pac-nor 30" stainless select, 1-15 twist, fluted, .800 at muzzle.Stockade Coyote Stalker stock.Warne rings and bases, and a Leupy 6.5x20x50LR.

Load development was a pain to say the least I was having problems with high pressures with fairly mild loads until I changed from magnum primers to large rifle, pressures came way down with only a very mild loss in velocity (25 fps).accuracy wise it shoots fantastic .5 to .75 with 3 diffrent bullets and 5 diffrent powders and the largest groups were just over an inch, all testing was done at 100yds.And i will admit I,am nowhere nere a benchrest shooter.

Powders I tried W760, H414,H4350, Viht 550 and Varget. Most accurate was H4350, Highest velocity with 110 v-max was with W760, and highest velocity with Nosler 125BT and 150 BT was Viht 550.

Final outcome all are magazine length;
110 V-max, Norma brass, CCI LR200, 75.5grs W760 = 3975fps .75moa
125BT, Norma brass, CCI LR200, 71.5grs Viht550 =3900fps .5moa
150BT, Norma brass,CCI LR200,66.0grs Viht550 =3475fps .75moa

These loads are Max in this Rifle if you want to experiment with yours please start 10% under and work up.

Eventually I want to try some 155 Berger vlds but that will have to wait until after hunting season and i'am currently waiting on another barrel from Pac -nor for a 6.5-300 WSM that i am putting together on another 12fvss, Speaking of does anybody have any experience with this round?

Re: .300 Varminter

Interesting... I've often wondered what my .300 WSM would do with light bullets - but mine has a 1:10 twist and a mere 24" barrel as opposed to your more specialized setup. Glad you got it shooting well for you. Ought to vaporize varmints!

BT, the 300 Varminter was possibly the most talked about cartridge on this site. i've referred to it as "folk lure legend" but not much is really known about it. did Richard Franklin build your gun?

Guy, I also have a 11 twist 24" tikka and I had pretty good luck with minimum testing and 110 vmax's. I was using H380 and Varget and although I had limited testing, I was getting about 3600 fps with a light charge of H380 and .75 MOA groups.

Re: .300 Varminter

from what I understand that 300 "Varminter" should not be chambered in anything less than a Bat or Nesika action so it can be pushed well past the sane limts of what the 300 WSM was chamberd for.

The 300 "Varminter" is the same spec as the 300 WSM just loaded to stupid pressures and renamed , possible putting unknowing people in danger.

Their was guy here that raved all about this round and how it shoots lazer flat and is instant death to anything within a mile of it. He spent the funds had the gun built and was never seen or heard from agin and a couple weeks later the gun was forsale on another site. I personaly think that it kind of unsafe to call this round one thing and its simple nothing more than an overloaded 300WSM , if it were me I'd have blown the shoulder forward at least .050" so that these over loaded round can't be chambered in guns not built to handel these pressures , so that accidental blow up is avoided.
I don't think that your loads are near the overpressure loads that this round is claimed for , I think that 4200fps with the 110's and 4000 with the 125's

Re: .300 Varminter

Yes I saw all those discussions thats actually one of the reasons why I put it together just to see if those velocity's were possible. To me "stupid pressures" are exactly that, regardless of what action there on I cant see getting over the velocitys I am at In any action without opening the bolt with a hammer and junking the brass every time you pull the trigger.Call it what you want its still a 300WSM no more, no less.Its a barrel burner for sure but the way I see it if I hit a coyote every 3 shots and I can get 1200 rounds through it, well that will be the best 500 bucks i ever spent.

Actually I was looking at the post awhile back about the 375-408 chey-tac,how about a 260gr Nosler BT at 3500fps can you say wolf gun
