Seating Depth

Seating depth IMO is what can drastically change a load/group size. It’s much more important than the powder charge.
Do a seating depth test in .020 and you might find some interesting results. You can fine tune after initial results also.

That's generally what I do, just go by listed COAL. Seems to work just fine. I got interested in messing with seating depth a while back but I've never really done much with it. The only time I've ever loaded to magazine length was this past spring when trying Ramshot Big Game in my 7-08 with 139grn Hornady Interbonds. I seated to mag length in that case just because I thought the secant profile was going to give the bearing surface a pretty long jump to the lands, so I loaded long. I haven't messed with it since, but that produced a real good load. Its 1 MOA and zipping out there at about 2920 fps.

Sounds like a good load that’s smoking right along.
