After a long wait until the 650 gr. Woodleigh BPE projectiles arrived from midway; I shot my .577 2.75" with them, bullets.

For those who don't know, this is a 1889(ish) rig with damascus tubes. Scary stuff indeed.

Using my superior powers of deduction, I mathematically concluded that 65gr of IMR 4198 would be a safe starting point. Naturally, I was correct.

It shot apart (7"), but held together.

I'll add one grain until it's 4" or so.

Remember - damascus. I'm not going to push this ole girl.

God bless the .577!

P.S. Recoil from this 8.5 pound rifle is... stout.
