so ive been doing a lot of research on the different 6mms and am thinking about building one and have narrowed it down to 3 and am looking for some input from you guys shooting them.

6XLR...from what ive read and seen in person the 6XLR seems like the one to go with...one of the match directors shoots the 6XLR at our matches and from what he has said and from what ive read the 6XLR seems to have the the best barrel life of the 6mms and also seems to have the best ballistics as it can shoot the 115 class bullets over 3000FPS with no presue issues.

6mm creedmore...last match 2 ppl were shooting the 6CMs and they were pretty impressive in the wind...i think they were shooting heavy bergers at 2950FPS.

243AI...this is another cal ive seen at our matches that preforms VERY well but ive hear and read they are barrel burns when yoiu turn up the heat.

im leaning more toward the 6CM or the 243AI but would like to hear what you guys think as far as pros and cons of the 3...what bullet,brass,powder and primer combos your shooting...barrel life...and or what ever other advise you have about the 3.
