Calling all RCR 300 WSM varminter owners

[fordnutter]

Hi Guys,
I've procrastinated for far too long on building a 300 Wsm varminter! I have a suitable Barnard P action on hand with McMillan stock, Several bags of Norma brass & just ordered my Redding competition dies from Sinclaires.
The majority of my varminting is in the 300-600yard range, I'm not hung up on BC or having to allow for more wind as a result. What I want is maximum splat & air time! Do I barrel with a 1-16 to 1-17" twist for the lightweights or go 1-13 to 1-14" twist for the 150gr weight for the best carnage results?
I was hoping a fellow 300 varminter owner could offer some advice from their experience.

P.S - Before you ask I'm not "Wildcat" so be gentle I just want to splat larger size varmints (Wallaby) which can get as big as 10kg & not have to worry about ricchochets taking out farmers cattle.

Im shootin 168 grain bergers outa my 10 twist 300wsm....plannin on loadin 215s in it once i get my reloadin stuff set up....the 168s blow stuff up pretty good....

Anything you shoot out of that cannon will explode varmints. I would recommend thinner jacketed bullets, 165gr+. I think target bullets like the Sierra Match King or Bergers would be ideal. Have fun.

BTW, nice raccon. Pretty slick - just hose it out and its a ready-made hat. Davey Crockett style!

Ha ha! Yeah, that one became fish food, the catfish went nuts on the blood spray on the water, so i fed em the rest, 200 and some yard off hand shot with a savage mod 12 vlp bvss....

I would bet the 110 grain V-Max would produce an awesome splat, but I don't know if they'd be good much past 3 or 400 yards. The 185 Berger does nasty things to coyotes and I imagine similar carnage on a Wallaby.

Fordnutter i would say build it how ya want and run bergers, they just flat blow holes....im shootin HSM factory loads with the 168s, coons, yotes and ground hogs pretty much splode....oh and crows turn into a puff of feathers....even with 1/10 twist they are groupin 1/2 moa(80°f and up) or under(79° and cooler)....

Looks like the heavy weights might expand just fine in the 300 WSM. I just want to minimise riccochets that could take out farmers cattle. I 6mm I had loved to bounce Berger 95gr VLD's off hard ground & that made me really nervous when the target i was shooting was in amongst a large herd of cattle.

I original was going to chamber for the 208gr Amax to minimise wind drift but was told that Hornady were going to stop production of the Amax....Any truth in this?? I know the Amax expand well but I didn't want to hedge my bets on one bullet in case my barrel didn't like them.
