So I’ve been loading 200 grain SWCs for some time with 5.6 grains of HP-38 seared to an OAL of 1.250”. Typically using bullets from Brazos (H&G 68).
I recently loaded up a large batch of ammo, only change being I started using Blue Bullet’s SWC. Nothing else was changed. All cartridges passed the case gauge and go through a Lee FCD as a last step.
Im getting a lot of FTF now which was never an issue when using bullets from Brazos. Again I haven’t changed the OAL or anything else. I’m assuming OAL is the issue but I tried 1.230” and was getting issues just dry cycling. In about 75% of the stoppages are cured with a “tap”, the other 25% require a “rack” ejecting the problem round. I’ll also add 10 round mags exacerbated the issue and won’t even feed the top round.
Any thoughts from the crowd here? I posted elsewhere but didn’t get a lot of help.
Picture of the failures I’m getting.
