168 amax over varget in LC 08 cases full length resized powder just starting to compress at 45gr with OAL at 2.80" netted 2630fps in my 20" AAC-SD this past weekend. Started at 41gr at 2391fps and worked up in .4gr increments. No pressure signs but a Remington is pretty open so it takes a lot to...
Odds are that cartridge was tested in a universal chamber and a 24" barrel. Your velocity may be higher. If it is then it will probably only be 50-60fps higher. But, other factors can determine velocity. I would shoot it over a chronograph if one is available. Your other option is to put up a...
I think instead of just going with 25gr, I would load up to 25.6gr(if pressure allows) and see if my grouping and velocity was pretty much the same. If so, I would go with 25.3gr and try seating depth changes with that. This would provide a load that is not too sensitive to changes such as...
