The TTSX is the most accurate I have found. Right at MOA edge to edge in the SOCOM. The FTX are pretty close. If I were to play with more powders I may be able to squeeze it down a bit. But since we are talking 45cal bullets I do not feel it is really necessary. I am not looking for a tack driver here. That is what the 264LBC is for.
With that, the TTSX is my primary hunting round. I have about 200 loaded. The FTX is second in line but much cheaper, almost 1/2 in cost of bullet. I also like the 405's but they can be punishing and again not necessary for the animals I will be going after.
