Both rifles will be extremely accurate, however, for extreme2 accuracy lol I believe the LRPV has the upper hand.
1. The action is stiffer due to the fact it only has a port in the left side to eject from. It is a bridged receiver with the feed ramp machined into the action, both of these make it stiffer. The action also attaches to the stock with 3 action screws, not just two.
2. The barrel is a minimal-tapered full 1", no flutes.
3. The stock is a HS Precision, with a full length aluminum bedding block.
I have one of the right-bolt/left-port model in 22-250 1:12" twist. It's awesome. However, it is quite heavy. My gun weighs in at close to 16 lbs. with scope and bipod. As of right now tho it averages about .2 - .3" 4-shots @ 100 yds. with 52gr FB HP bullets. @ 450 yds. I shot a group of about 2" without correcting for wind (the group height was .79", it was spread out on the horizontal).
I have a review for my rifle @: Savage model 12 long range precision
Although, they now make a LRPV with a detatchable box magazine. Just some food for thought.
