I am not new to reloading by any means, but I am running into a problem when I am reloading 308 for my gas guns.
The problem: Depending on the rifle, the rounds are either chambering and are hard to extract by hand, or not able to completely chamber and still hard to extract by hand. They shoot fine and cycle fine, but problems by rifle are: SCAR 17 hard to extract by hand but otherwise work fine. Colt 901 very hard to extract by hand and hard to get them to chamber from the magazine. If I lock to bolt open, insert a full mag and release the bolt, the bolt doesn't quite fully go into battery. If I manually put the first round into the chamber and let the bolt down, then insert the magazine, it runs through the whole mag without a problem.
Specs on the ammo: Once fired lake city brass, wc844 mil powder, magtech primers, and 147gr full metal jacket bullets. Brass is withing spec length as well as the cartridge overall length, fit fine into 20lr pmags.
Specs on the reloading equipment: RCBS AR series 308 small base dies, Lee turret press, crimp applied with a lee factory crimp die.
As it sits right now I am kinda stumped, the 223 that I have loaded up with the exact same set up, including RCBS AR series dies, work perfectly. The only thing I really noticed between the commercial ammo I have that works perfect in the 901 was it seems like the shoulder hight on the reloads is too high. The only thing I could think of there would be that maybe the ammo was shot out of a machine gun with a long chamber, but it seems like my sizing die should fix that.
Any ideas guys?
