[QUOTE="engineer40, post: 1609389, member: 90399"] Thanks for the suggestion SMK1000plus! He actually owns a Ruger American in 450bushmaster now and likes the gun. I think that is a good suggestion to have him look into one in 223. I shoot the 77gr Sierra TMK's in an 18 inch 1:7 barrel. I get 2,740 to 2,750fps with zero pressure signs... which I'm very happy with. That's at 5.56 pressure, not 223. Using IMR 8208, which people say is very temp insensitive. The TMK's have a G1 BC of .420 and even though it's not a hunting bullet, seems like many guys use them for hunting. I did get an accurate load at 2,790fps avg, with very little to no pressure signs... but the SD was way too high compared to if I backed off just a bit. I load them really long, 2.266. They BARELY fit into a Pmag. :) [/QUOTE]
