Fellow shooters, earlier this year I purchased a Howa M1500 223 24" Heavy Barrel w/ 1:12 twist. Through various hand load test I found the sweet spot for this rifle with 55gr projectiles. I'm now looking for a 223 heavy barrel varmint rifle with a 1:8 twist. I want to load and shoot heavier rounds but my Howa doesn't like them at all. So toss up some suggestions and I'll go from there. Thanks
