[QUOTE="Carlos88, post: 2278592, member: 116554"] The Hornady has a different ogive than the Accubond. I would start with 2.750 and progress in .020 and watch your brass and primers. Shoot groups with a "dirty" barrel (about 5-6 foulers), 3 shot groups for expediency. Don't clean the barrel until your groups go to pot. I've done this many times for friends rifles and have been able to find more than acceptable groups. Those rifles were glass bedded and free floated and ensuring the front base, front screw does not touch the barrel threads (I've found that with lightweight Talley's). You can fine tune later if you want. I realize this kind of goes across the grain but it works. I have a .260 Mountain Rifle that drove me crazy. I cleaned and cleaned and shot and cleaned and shot again. Every 120'ish grain bullets were tried. No consistency. Fliers, blah, blah. I was so frustrated and was convinced I needed a new barrel. On the last trip when I hit "pay dirt" the rifle started with its usual fliers, etc. I had 15 rounds left in the box so I posted a clean target with 5, 1.5" dots on the paper. Shot 3 at each one without stopping. It was in July (in TX). After I got to the 9th shot the group shrank. The barrel was almost glowing. Smoking hot. By the time I hit 13, 14 and 15 the group was well under an inch. I kept it dirty for about 50-60 shots then groups went back to crapola. Cleaned and didn't worry about the first 9 anymore. Saved myself a rebarrel and had a monster in the bag. [/QUOTE]
