I am looking at getting a 7mm rem mag. There is a lot of talk about case bulge above the belt. I've been wondering if a collet neck die will give more reloads before this happens, and how many reloads could typically be done before this is a problem.
You cant unread what you have read but you can ignore it iv loaded 100s apon 100s of rem mag rounds and never had an issue
Reach out if you need a hand obviously local
Yep, local. Thanks for the offer, I will be in touch when I have it.
The type of sizng die you use wouldn't do anything to stop that bit of the case expanding. It's caused by shooting repeated hot loads and the problem is that once it has expanded, traditional sizing dies can't touch that bit of the case to rectify it. But if you just don't repeatedly shoot hot loads then you're not gonna have that issue.
How many reloads will you get? The spiciness of the ammo vs the dimensions on your chamber vs the dimensions and toughness of the brass and how meticulously you care for it... that's what will give you an idea of how long that piece of string is.
Cool as rem mag is a favourite of mine
Always a great chambering choice :)

Im down in Kapiti, your welcome to reach out if Kelton is occupied. many years experience loading for 7Rem.
neck sizing is not the best option, the length of the case walls lends itself to major expansion, full length sizing has always proofed to be better suited for me.
Contrary to popular belief I chose 4350/AR2209 and 168gr pills.
It all comes down to how big the chamber is, some of them are huge on the 7RM & when you full length size you can get a double belt or the start of one.....
Hmmm A-Tips :cool:Quote:
