[QUOTE="nkyshooter, post: 1394375, member: 83787"] Pretty much all the arguments are here in the thread above ... 6.5-284 likely to push the pills a little bit faster than the 260 AI ... BUT 260 AI wins for me due to: - Better brass life - Better barrel life - Short action vs Long (this does in fact have a true potential accuracy advantage) - Brass options and availability (if you HAVE to you can form off 308 which is EVERYwhere) My 260AI is built on a savage 10 with a 27" 1:8 tw barrel (.675 at muzzle) from Jim Walters (he uses Green Mountain barrel blanks ... not high end stuff) all in a B&C m40 stock with a heavy SWFA 5-20 on top. Guessing in the 12.5lbs range but is just an educated guess. What is NOT a guess is the results I get ... I'm getting honest 5 shot groups well under .5 MOA and typically in the .3's. I'm using Berger Hunting VLD's and using my load of H414 (don't laugh - it meters PERfectly :) ) I get 2925 fps at 70F and 650' altitude. While I know I could get more velocity if I went to another powder, I've taken an approach of using enough cartridge that I don't have to push for maximum potential velocity but rather find excellent accuracy and know that at whatever velocity it turns out to be, it will be more than enough for anything I'm planning to do with it. My 260AI is the #1 favorite at the 1000 yard range when a group of family/friends all go together and try out different rifles, etc at different ranges. The #2 and #3 are my 6BR and then my Savage Ashbury in 6.5 Creedmoor. If I had a 6.5-284 though - I suspect it would be in the short list of the favorites :) Last thought is this ... while it won't push them as fast as the 260AI or the 6.5-284, the 6.5 Creedmoor is still PLENTY capable at 1000 yards as is a straight/standard 260. I like the AI for the increase in brass/barrel life and as long as you like to reload is a great choice. If you have need to rely on factory ammo, the 6.5 Creed begins to take over as the better 'tradeoff' ... Post some pics when you're all done with it so we can all "lurst" after it a bit ...
