I recently purchased a Savage m12 BVSS in 6.5x284 (long action). I've done some load development with 140gr Berger vlds and am very pleased. Two loads, 51gr of RL-22 and 52.5gr RL-22 are shooting at/under .3 and.5 inch@100. By the book the 52.5gr load is max, but there is no showing of any signs of pressure. I don't think I need to push it any harder as this should be near 2,925-2,975fps, and thats just great for me. I'm seating the 140 VLD's 0.001 from the lands. the throat on the rifle is pretty long as the length of the load is 2.500 to the ogive. This means the bullet is only in the neck ~0.149, which is not much. I've tried loads with them seated deeper into the brass/neck but they didn't group very well. I don't think I'm going to have trouble with recoil shifting bullets in the neck when they're in the magazinge as recoil is very light. Anyone think I might have trouble here?
Secondly, I want to try 140gr Amaxs. I always here folks talking about Bergers and jamming them to the lands or loading just a few thousands off the lands. Any advice on the Amaxs and distance the lands?
By my rough measuring the bearing surface on the bergers is ~0.500 and the bearing surface on the Amax is ~0.575. So if proximity to the lands is not as important, I might be able to seat them further into the neck.
I intend to use the rifle mostly for a steel safari target type match (300-800 yrd type shooting), but would like to use it for long range deer and antelope hunting as well (therefor, my interest in the amount of bullet sitting in the neck).
Lastly, without the 140gr berger loads showing any signs of pressure at a book max load and the bullet not touching the lands, would I be pushing a safety factor by starting load development with the 140 amaxs closer to max if they were not touching the lands as well?
Thanks!
