Thread: Reloading 284 Winchester for a BLR

This has probably already been covered but couldn't find any obvious reference, so here goes.

Reloading the cartridge for an old mate.

Knocked up a couple of dummy rounds using Nos BT 140 grn and 150 grn using specified COAL. Fits in the magazine, just! Projectile though, seated that deeply into case I suspect I'll need to crimp the case mouth. Could use 120 grn, much less of an issue being somewhat shorter. Not sure that the barrel rifling twist will stabilize them, I think it's 1 in 10 but not sure. Google hasn't helped.

Secondly am using 2209, no specific data but I'm pretty sure it's equivalent to IMR4350. That said I don't want to bet my mate's well being on my semi educated guess.

If anyone's dealt with the matter before, advice will be appreciated.

Cheers
