[QUOTE="rooster721, post: 798636, member: 40654"] I ran loads in my 264win yesterday, maxed-out around 3100fps & actually was seeing about 3/4" groupings til my barrel began fouling... long story short, groups were difficult to measure because my 1:9 is a little short for stabilizing these bullets (hole were slightly key-holed) ...even at 3100* 1:8.5 might work if you can push it as fast (or faster) But only trial will really tell. Can be guaranteed my re-barrelling (which is coming up very soon) will be done with an 8 or 8.5 twist.. specifically to shoot these 160's! Here's a pic of a single bullets "keyhole" (that I'm talking about) ..not quite what you want to see* [ATTACH]21133.vB[/ATTACH] [/QUOTE]
