[QUOTE="diggler1833, post: 3776405, member: 48072"] Picked a sub-par weather day to do it, but I've been chomping at the bit to start messing around with my latest range toy. Rifle: FN SPR A2 bought new. Krieger 1:8 twist, M24 contour, 26" threaded (although I doubt I'll ever put anything on the end). I bedded the action and Krylon'd the stock to give it more of an M40A3 appearance. Optic: Bushnell DMR II 3.5-21x50. The rig: [ATTACH type="full"]271338[/ATTACH] ***Load data*** Brass: Lapua Bullet: Lapua 123gr Scenar Primer: CCI BR-4 Powder: Varget I've only put 25 rounds through the rifle so far, and they were the uber expensive factory Lapua 123gr Scenar. After a couple shots and cleans, I put four (5) round groups downrange that were all in the .6 - .7 range. Decided to try 30 rounds of handloads in 3-10 MPH winds that were shifting a lot. It is really too early for load development, but what the heck. If I can narrow it down some, I'll really buckle it down after I get about a hundred rounds down the tube. Went from 35.0 to 36.5 in .3gr increments. Looks like I'll have to sacrifice a piece of brass to make an OAL gauge, but until I do that I just went .005 longer than the factory stuff. You can really push the 6.5x47 hard (way over book max), but this is a recreational rifle for me and not a comp gun. First group of handloads after the CBS was in the .4s. Promising for sure. Second group of 5 shots went into the .4s again even with a full value wind at this point. Then the groups progressively opened up with each increase in charge weight. Made a couple .7s, a .9 and then finished off right at an inch. The vertical dispersion wasn't good, so I can't blame the wind. The winner of the day: [ATTACH type="full"]271334[/ATTACH] At this point I'm going to fire the remaining 25 factory rounds that I have, and then try to fine tune a bit around the above load. Hopefully my barrel will have sped up by that point and I can break the chronograph out. It'll probably also help when I start reusing the brass...this is all on virgin cases too. My goal for this thing is just an easy going recreational rifle that stays solidly under 1/2 MOA. Enough babbling for now. Will update whenever I get more time to piddle. [/QUOTE]
