[QUOTE="Long Time Long Ranger, post: 527568, member: 505"] Monometal bullets may be the best for the super performance cartridges such as the 6.5 SIN and 264 STW. They will not come apart at high velocity and retain excellent accuracy at high velocity. They also perform well on game at high velocity without blowing apart. GS and Cutting Edge make good high bc monometal bullets in 6.5. The barnes ttsx would be a good one in that price range but the bc is lower. This is all guessing because the SIN will be faster than my 264 STW. I can shoot the 140 Berger at 3350 fps out of my STW but others tell me that is the absolute max for the berger. The problem is hitting game at close range and the bullet blowing up. The monometal will not do that. Eaglet I have shot the 185, 225 and 300 in the 338 SIN and those would be max velocities in my 24" barrel with powders I have tried. I am focusing on the faster burning powders for this cartridge considering my short barrel and light bullets. A guy with a longer barrel using slower burning powder than me may top what I have done. The cartridge seems to be very easy to load for and shoots very well with max loads. I have another batch of bullets loaded for testing this week and ordered a new batch of Cutting Edge bullets this morning for more testing. [/QUOTE]
