Re: 168\'s and LTR twist??????
Its good to have another conversation with you too!
My opinions on velocity of the 168 in 12x is somewhat the same. 2600-2800 is hard to beat. This is only my opinion though! I have used the 168 at 763 yards on a sheep and it din't open up though. Velocity was 2661. 4000' in 60 degree air. I dont use them much anymore due to that fact and also their uncanny ability to tumble after about 800-1000 yards depending on the air density at the time. The 178 AMAX has filled every one of my needs. It opens nice at low velocity, stays supersonic to 1K and is increadibly accurate. The 12 twist will still work fine for the 175 SMK and the 178. Not saying you should switch to them, just maybee give em a try.
Also, just out of curiosity, what appeals to you about the LTR over the PSS?
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
