[QUOTE="trent.g, post: 1724242, member: 111498"] Hi guys. Been a lurker on these forums for a while as well. I realize this is an old thread, but wondering if anyone had an update on seating depth. I too bought a Sako A7 in 7 Rem Mag in Dec, 2018. (It's the Roughtech model with the aluminum bedded stock and heavy sporter fluted barrel.) Couldn't get it to shoot worth a ****, sent it away to Stoeger Canada for warranty inspection and they said it had excessive headspace. They replaced it and I've been fighting with the replacement gun since April. Some days it shoots ok, some days it doubles the groups for no apparent reason when I re-test the recipe. It's like every time I zone in on what looks like a sweet spot it won't repeat the results or improve on them. Mostly max mag length so far trying to find the best powder charges. I started changing the seating depth drastically in the last week and got a couple back to back bug hole groups that I need to re-test to confirm they aren't a fluke. Both tested max COAL for the gun were 3.430". Max mag is also 3.33" on my Sako. -Hornady ELDX 162 Sako brass 69.3gr H1000 CCI BR2 3.29" COAL - about 0.140" jump! 1-4 in a bug hole + 5th shot failure to fire. Probably mis-handled the primer? I haven't chased variations on the ELDX as thouroughly as the ABLR. I got more consistent results around MOA with H1000 than H4831, and pretty much dropped from max mag length 3.33" to 3.29" on a whim to try out. Needless to say, I was shocked at the group it produced last night, and am skeptical on this one. -Nosler ABLR 168 Nosler brass 65.3gr H4831sc (No pressure signs till 65.6gr on a warm day...) CCI BR2 3.295" COAL - about 0.135" jump! 1-4 in a bug hole + 5th shot flier measuring 0.92" H4831 initially tested better than H1000 overall for this bullet. I had a really hard time picking what powder charge to focus in on because nothing was getting MOA. I played a little with 3.325", 3.32", and 3.31" without anything notable. Also tested 65.3gr in all lenghts. Velocities seemed a little more consistent with the extra 0.1gr powder. but then I managed to get MOA with 65.2gr H4831 @ 3.30". Cold shot in the group high, and the subsequent 4 shots within a 1/2". Re-testing that same recipe netted a 1-1/2" shotgun pattern... 65.3gr @ 3.295" may or may not be the solution for me, but I have to re-test.

I'm also running about 150fps slower than Nosler's reload data, but that's not the end of the world. Has anyone else had good results with such a huge jump to the lands? I really want to make this bullet work in this gun, but I'm just about ready to cut my losses on it and buy a Browning or something.
