After all the buzz I've heard on this forum about Hammer bullets, I've decided to give them a shot (pun intended). I shoot a straight 6.5-06 with a 1:10 twist. Since this rifle was built, over 50 years ago, it's always been shooting 120 grain boat tails (Nosler ballistic tips for as long as I've had it) driven by 54 grains of IMR 4350, as this is supposedly the only round the maker found that would stabilize. This round chronos at 3,135 fps (average) and has always been a tack-driver for me. The ballastic tips can be problematic at times, wreaking devastation when they hit bone but acting like a sabot anti-tank round when they don't (years ago I hit a whitetail broadside, through and through completely missing all the ribs and it sucked a good portion of his guts out through a quarter-sized exit hole).
The Heavy Hammer Hunter bullets I ordered are 121 grains, one grain heavier than what I'm currently shooting, so I thought I'd just start with the same load, or maybe back off a few grains. The HHH box says a 1:9 twist rate is recommended so I'm not sure how much difference a 1:10 will make.
I welcome your thoughts and advice. Thanks !
