[QUOTE="Fiftydriver, post: 294728, member: 10"] As far as actual performance difference, there is not alot of difference. The Sniper Tac and Xtreme are nearly identical in case design but for some reason they load the Xtreme to very low pressures. I believe this is because the brass they use will not take any higher pressure. Because of that, it will run around 150 fps less then the Sniper Tac with same bullet and barrel length. The 338 Allen Magnum is a bit different, shoulder angle is sharper and shoulder location is moved forward around 80 thou to increase the length of the case body. When the 338 AM will match the Sniper Tac when loaded to the mild Xtreme pressures or will be 100 fps faster then the Sniper tac when loaded to top pressures. In all honesty, all three are dependant on what brass they are using. Most current brass will not allow any of these to reach their full velocity potential. I generally load my 338 AM to 3300 fps in a 33" barrel length but many of my customers are pushing 3400 fps with the 300 gr SMK with good brass life. Professionally, I would not recommend the Xtreme simply from what I have seen in the rifles. Other then that, take your pick. One bonus of my 338 AM is that I sell fully formed, correct headstamped cases for my 338 Allen Magnum so its no different to load for then say a 300 RUM, just alot larger!!!! [/QUOTE]
