[QUOTE="Salmotrutta, post: 1734607, member: 110250"] I just sat down to ask this very question! I have a T3 .243 donor rifle collecting dust already in a Manners T3. I am also going to run suppressed and don't want to mess with the standard bolt face or aftermarket bottom metal or mags. Looking to maximize effective range for deer/sheep size critters with a 20-22" carbon bbl. Preferred bullets are 168 LRX or 169 Hammer. Looks like a 1 in 7.5 or 8 twist? Also it would be nice to find factory ammo in a pinch and have quality brass available. So far my QL pondering says in a 280 AI I can launch that 168 with RL 26 right at 2900 fps, and at an elevation of 7000 ft that retains 1800 fps and 1200 ft lbs at 900 yds. I am not sure about the 6.5 PRC (which would require bolt face mods) but every other 6.5 with a standard bolt face and a 20" bbl, including the 6.5 RPM doesn't seem to match those numbers with a 3.34 COL. Anything out there I might be missing? Thanks to the OP for the original post and thread. [/QUOTE]
