Hi,
I’m going to work up loads for a whelen I’ve acquired based on a Gew 98 mauser. All of the bullet designs I’ve seen so far don’t seem to include a crimp groove. But I did see Lee offers a FCD for the Whelen. I’m intending to hunt with my loads, so they will not be bunny farts.
Should I rely on neck tension or should I use a crimp? And is the going wisdom for a caliber like this, if neck tension, .003 for the field?
Thoughts and guidance would be greatly appreciated.
For my rifle rounds, the only ones that get a crimp are those intended for autoloaders. I would be comfortable with .002 neck tension on rounds for a bolt action rifle unless you're seating the bullet hard into the rifling. GpQuote:

I have seen no reason to crimp for the 35 Whelen with it or the 9.3 x 62mm Mauser which has noticeably more recoil the bullets in the magazine have showed no shifting in the case
Just because there's no crimp grove (or cannalure on jacketed) doesn't mean you can't crimp, and the the fcd isn't much of a crimp die, it's more like a sizing die with no guts(I've got one I use as a pass through sizer for 10mm). Looking, the rcbs seat die will roll crimp, so I'd give it a light crimp.

Light loads or light rifles can want crimping, when you otherwise wouldn't.
A reduced load that seems promising but isn't burning clean, might.
Full power loads that are ballistic twins needn't crimping for a 9 pound 35 Whelan but do for a 6 1/8 pound 350RM. Yes, the Whelan was more pleasant to shoot; but the Remington is very nice to carry.
There are three different types of FCD die. Bottleneck cases get the nice collet type crimp (which is where the term Factory Crimp Die originated). It works really well and can be adjusted to just take out a flare (which is how I use it) or it can crimp.Quote:

If your sizing die does it's job and your bullets are not larger than standard the crimp ring doesn't do anything.
For the OP's question, I do not crimp unless they are for an auto loader.
