There's more calculators out there but I used these 2(Thanks for the link PR). I came up with an average of specific gravity of about 3.0 for 1 in 12 twist. 1 in 15 average was 2.0 with the Berger being at 1.66, marginal. After talking to Nosler and their test barrel maker for 110 grain, H-S Precision, and wanting to shoot up to 125 grains, specifically Nosler's ballistic tip hunting ammo, in a 20" barrel I've decided on the 1 in 12. Consensus was it would give me more room to load similar rounds and wouldn't pigeon hole this particular upper to just one type of ammo. Now just have to pick a barrel maker. Thank you all who contributed to helping me solve my little dilemma
