[QUOTE="codyadams, post: 2246701, member: 87243"] Got some updates on the 140 .277 in a 19" .270 Sherman (standard Sherman, modified .270 win case) 19" 8 twist Mcgowen barrel w/supressor Formed Norma brass CCI 200 primer 3.500 OAL (Max mag length) which is a .077" jump Reloder 26 [ATTACH=full]287014[/ATTACH] As you can see, there is a massively wide node around 3100 fps, for a 1.2 grain spread there is a 17 fps e.s., so I loaded up 63.5 grains. That entire spread also grouped around 4" at 600 yards on the ladder. Also, 64.3 had the very first signs of pressure, faint ejector mark, but no bolt lift yet. This was shot at 78° f. With a .333 G7 at 3100 fps, this load is doing pretty fantastic and should work great. Will get on game performance on a few speed goats this fall! [/QUOTE]
