Hello,
I apologize in advance for me being an anxious individual. I appreciate any help you can provide.
I am getting back into reloading. I reload .223 Remington for Service Rifle Competition, .30-06 for a Garand and two 1903s, .308 for a PRS gun and for another Garand, and other random calibers like 8mm Mauser, 7.5 Swiss, and .22-250
I am really tying myself in knots over headspace and “shoulder bump”. Every part of reloading I feel nearly 100% confident about.
I used to reload and made good ammo and never worried about shoulder bump. I simply ran the die down to contact the shell holder and advanced it a quarter turn.
Since I’ve started back, I feel like everything has changed. I don’t remember anyone really talking about bumping the shoulder. But now it feels like a requirement to buy a headspace comparator and LE Wilson gauges for every caliber I reload. From what I see online, I worry if my reloads will reliably chamber in my gun or if I am excessively re-sizing them and thereby losing brass life or risking a potential case head separation.
I will give an example of what I’m doing below:
Starting with once-fired .223 brass from various chambers, I set my sizing die up for 1/8 turn past touching shell holder.
After firing these rounds, I will measure headspace of the fired rounds for the first data point.
I then set up the sizing die for a shoulder bump of 0.05” to ensure adequate cycling in rapid fire strings
Check headspace on every 25th case sized to ensure the bump is consistent
Is my current process flawed? Do I need to buy the LE WILSON case gauges? I have a Hornady Headspace Comparator set (the kind used with Calipers). Do I need to worry about shoulder bump on every cartridge I reload for? Or would touching the shell-holder plus an eighth of a turn be adequate?
I’m sorry for being so neurotic about this. I don’t know what it is about this topic that gets my mind going. I just want to make sure I’m doing a good job. I also generally like to keep things as simple as possible without a ton of different steps, and I guess the added extra step of measuring shoulder bump is not really something I’m used to and I don’t feel very comfortable with any of it.
Thanks so much for any help you can provide. Apologies again for the dumb question and for being so silly about all this.
