Re: Suggestions for varmint rifle project
My first choice would be the 243Ai with a 1-8 twist , you can get Lapua brass and the barrel life is decient , shooting a 105 A-max bullet its a good 1000yd varmint gun and I woulden't hesitate shooting a mid sized deer say 200lbs out to 500yds with that setup.
second choice would be the 6mm-06 , not the Ackley version simple to aid in conserving barrel life by not having to shoot fireforming loads , again with a 1-8 twist , in either case I'd opt for either a Hart , Rock Creek or Broughton barrel so you'll have 5-6 lands and grooves which are not as hard on the thinner jacketed tatget and varmint bullets. Also the 6mm-06 you will be able to use Lapua brass which in my oppinion is the best out their.
You could also try the 6mm-284 which will balisticaly do the same thing as the 6mm-06 but it can be fitted in a short action but is beter suited in a long action and they have great brass for it but it is somtimes hard to come by due to the popularurity with BR shooters.
The 6.5-284 and 6.5-06 are both also great calibers and will offer a little better barrel life over the 6mm versions , the only problem I have with the 6.5 cals as a varmint gun is the available bullets for it , the 95gr V-max is a good one but I feel they should offer more varity ,but if you wanting to shoot deer out past 500-600yds then I would certianly recomend the 6.5's over the 6mm's. I know that deer have been killed alot farther than this with smaller guns but I personaly feel that guys are pushing their luck by doing so.
As for your stock , a McMillan , HS Precision are both good synthetics and will be a little lighter in some cases than a Laminated but Joel Russo has a some nice laminates hes turning out.
