[QUOTE="Barkbuster20, post: 2059239, member: 116205"] I suppose if I did the same thing rebarreling the 7mm to 338 wm I could have it throated for the 230 gr eld x -- or 250 gr berger. Im guessing properly throating the barrel I could safely get an extra 100 fps with those long bullets. If I can get a good accurate load with the 250 gr berger at 2725 fps that puts me right at the performance threshold of 1800 FPS at 800 yards with over 1800 FT Lbs If I had to shoot the 230 eld.x because my rifle didnt like the 250.berger I would need a min muzzle velocity of 2730fps to hit its expansion threshold of 1700 fps at 800 yards with just under 1500 ft lbs 2750 fps would give me an honest 1500 ft lbs. Converting to AICS removable mag would allow me to go 3.6-3.7 COAL - 26 inch barrel throated out for longer bullets should allow me to comfortably hit the velocities needed - [/QUOTE]
