Competition shellholder 300wm

[ohiohunter]

Does anyone use Redding competition shellholders for their 300wm? Wouldn't these take the belt out of the equation?

Yes I use them. I never pay any attention to belts.

Broz is right...after case is fireformed, headspace off the shoulder.

Below is taken from Innovative Technologies - Reloading Equipment

"17) My belted cases always crack at the expansion ring after just 2 or 3 firings. What causes this, and what can I do about it?
This is caused by handloads with excessive shoulder clearance in the chamber. This can cause a combination of problems. Belted "factory cartridges" are made to headspace on the belt. This causes the first firing to blow the case shoulder forward - this can be as much as .020" to .030", and it really stretches your brass. Well .... that's bad enough, but if your handloads don't have 100% of the sizing lube cleaned off - your cases will stretch even more. Be sure to always headspace your handloads on the shoulder."

He also make a very useful collet die to resize belted magnums just above belt where most rifle dies don't get to. He has alot of good tips on the above web site...good luck 30-338
