[QUOTE="QuietTexan, post: 2920353, member: 116181"] Purpose of the rifle? If hunting or steel, IMO pick a length that fits, change powders until you get consistent groups of ~1", and run it. Heck, looks like you're already there and it's time to enjoy the rifle. Yes I know, it's not the most perfected tuned load of ideal precision ever made, but you have an external constraint to deal with, so if what you get it good enough then run it. I'm 100% anal retentive on making the smallest possible groups with some rifles. With others (like my Altus 6.5CM M5 mag fed, so basically same boat as you) I'd rather shoot it a lot then test the life out of it. I hit the jackpot with my rifle using Alpha brass, H4350, and Berger 140 Hybrids out of the gate - old rifle load shot under an inch, have never revisited the load since. I have a new 30BR that needs to shoot it's first 0.0x" group before I worry about trying to eke out another quarter inch at 100 yards from mag-limited Creedmoor that shoots better than it needs to. Just my wood nickel worth of thought process. If you want to tinker do a whole bunch of 0.005" intervals inside your mag length, BUT do it where the thing shoots like crap. So find a BAD powder node and move the groups with seating depth. Might be kind of hard to do at 100, since you have access to 500 run a 3x powder ladder for the worst possible group, load up 50 cases seated long with that charge, and start fiddling. Arbor press and LE Wilson die are the easy button if you don't have them already. [URL unfurl="true"]https://www.brownells.com/reloading/reloading-dies/rifle-reloading-dies/micro-adjust-bullet-seaters/?sku=749017451[/URL] That's what I do 👍 Sometimes seating depth is a small range, so work the other variables. I've made several mag-length limited guns shoot better than they need to without changing COL. [/QUOTE]
