Headspace, how much is to much for R8?
Just out of curiosity, when full length resizing for an R8, what do the brains trust reguard as ideal shoulder bump for an R8?
I have adjusted my FL dies as per Redding instructions to just kiss the shell holder and I am getting a measured 5 thou of setback, compared to a fired case in the same chamber.
Function is perfect in terms of feeding.
Is this ideal, or should I turn the die down slightly and reduce setback a couple of thou, or just forget about it?
Opinions please...

I think you need to get out more.
Sorry I can't help....my reloading skills and knowledge border on basic... at best.

Yes, recent years have been more reloading and not enough hunting...

why don't you come a shoot a few BGR matches up at Ripley. It's good practice.

Re: Headspace, how much is to much for R8?
Yes, I might just do that.
I am going to go out to Ripley with Mark (you met him yesterday I think) and work up a load for my Merkel double.
But I just have to fit a pad and get the lop correct first.

5 thou of shoulder setback seems a bit much. I would generally go for 2 thou at the most....

For hunting ammo I go for 2-4 thou with a leaning toward 4 just to be sure they chamber when I need' em too.... I don't make claims to great expertise ...

Re: Headspace, how much is to much for R8?
I generally agree with others and try to maintain .003" of shoulder set back. However I find that controlling that dimension precisely is not likely. Temperature,lube, number of times the case has been fired and whether it has been annealed or not contribute to a wide tolerance of where that shoulder lands. I finally settled on a window of .002" to .004 for most centerfire calibers.

Agree with what's been said. .005" is too much for good case life.

Re: Headspace, how much is to much for R8?
Thanks gentleman, I guess I was also wondering... does the R8 need a little more to lock into battery reliably, sort of like how a semi automatic does?

Didn't have a head space gauge to measure so I had no idea. But now that I have they have been sitting around 10 thousand. Having said that I have been using RWS, Lapua, Norma and Geco. I've bought in bulk so I'm probably 4 or 5 reloads in and I'll toss them when they start going. Today was the first Geco in 30-06 that I've had a neck split. I'm getting my act on annealing for competition and now setting the R93 to about 3-5 thou for each cartridge.

That should improve your case life, and you still have a margin for reliability.mchughcb wrote: ↑Mon Apr 01, 2024 5:22 am Didn't have a head space gauge to measure so I had no idea.
