I'm loading a Hornady FTX 325 grain using 60 grains H335 in a Marlin 1895 lever gun. With the long point on the FTX you have to trim the cases about .050 shorter in order to crimp at the cannelure and meet the correct overall length to function in a lever action.(that's the way Hornady factory ammo is).
The powder is about 3/16" from the case mouth and gets compressed.
My question is when I seat the bullet, it gets hard to finish seating as if there's too much powder. I have many compressed powder loads I've used over the years and never had this issue, the powder compresses and fits.
It seems to me and feels like the cartridge gets an air lock, like the bullet will pop back out, like its full of compressed air, near the end of the stroke it feels spongy.
I reduced the load to 58.5 and it's still amazingly accurate but still compressed. Loading the 45-70, the difference in velocity with a couple grains of powder is very slight. Still the same seating issue but maybe not as much.
I'm using an RCBS Rockchucker press with plenty of leverage and Redding dies with a separate crimp die.
Any ideas about this with the 45-70?
