You bumping the shoulder every reload? When I shot a .243 r700 it would take 5 firing of just neck sizing the brass before I need to bump shoulders. I didn’t have a comparator to measure growth after each firing but that leads be to believe 1 firing doesn’t stretch the brass to the full chamber...
I was trying to explain I don’t think the bolt head floats forward or backward in relation to the muzzle when the bolts closed. As far as needing to remove the ejector to carry out the procedure described, I’d vote no. I’ve done the procedure described with success but curious what others input...
I believe he’s asking if he resizes his brass long and chambers the long brass into the rifle until he gets and easy bolt to close (bumping the shoulder back the very minimal for his chamber) does he need to remove the ejector to get a good feel of when the bolt is no longer pushing the shoulder...
100% (of the back of the) bolt lug engagement (to the front of the receiver lugs). Go grab your rifle and work the bolt slowly you’ll notice when you move the handle down it pulls the bolt forward, that’s the hard metal action engaging the back of the bolt head lugs and pulling the sloppy...
It’s hard to understand your question. But I think when the bolt is shut and the lugs are engaged the bolt head is no longer just floating around. The back of the lugs on the head would be engaged or locked into place by the action.
The guy who really helped me along when I first starting shooting told me.. “Comparing groups is just another dick measuring contest.” I use that philosophy a lot with other areas of the shooting realm. Social media and comparing ammo sd’ are included.
Hornady brass & CCI 200 primer.
I agree completely. I’m also not interested in shooting 100 rounds over a chronograph just to gather a number. I’d rather just shoot and gather dope personally but I’m just a new shooter who doesn’t know his *** from a hole in the wall.
Factory savage rifle, hornady 140hpbt, rl16, lee turret press, chargemaster throwing charges. Had a 3 shot string with rl17 that had an es of 2 and sd of 0.8. I don’t think I do anything special, just found what my rifle likes..
I run 42.5gr of rl17 behind 140smk 140hpbt-m and 143eldx. Primer pockets will loosen up on 4th or 5th firing, atleast for me. I see 2750-2810fps depending on bullet out of a 20” barrel. After roughly 950 rounds I’m seeing about .06” of erosion according to my data.
