The 6.5-284 barrel on an old Savage has been a little disappointing, not a bad shooter just not good enough for long range prairie dogs. A 30-06 barrel came along with the trade and the guy said it was a real shooter but for some reason I just never got around to putting it on till now. So I swap barrels out and run a new batch of brass through the die to make them round (Knew there was a reason I don't normally buy Remington brass). Then started charging cases with powder for the 185 grain Berger VLD's........Daa what twist does the 30-06 barrel have?? $#!! the rod takes 13.25" to make a revaluation. Well not being up on the twist rate for the 30-06 I start paying attention to what is actually written on the bullet boxeslightbulb Berger has 1-12 for the 185VLD and 1-11 for the 210 Hornady says 1-12 for the 168Amax and 1-10 for the 178Amax Also have a box of 180 Accubonds, 180 BT, 180SST, and 168grain HPBT. Not probably gonna shoot anything bigger than a prairie dog so kinda figured I'd start with the 168HPBTs but without wasting any more ammo than necessary what bullet would work the best?? Does it pay to try the 180's???
