577 BPE Loading Help

Ward12constable,
The book I mentioned is "Shooting the British Double Rifle" by Graeme Wright. I have a few books on the subject but this one seem to be the most complete in getting a person started.
Good luck

Yea that book seems quite difficult to find. I found two on Amazon one for $2,000, and one for $4,000. Hope I can find somethings more reasonable. Like I’m the 250-500 range. I’ll keep looking.

I have a Greener .577 hammerless BPE 3”. Lonnie at Superior helped me regulate it. Recipe was 76 gr of 4198 650 gr Woodleigh soft nose. 1780 ish FPS. 4500 energy and huge Taylor knockout. Good luck ! Congrats.

PS, I consulted Ken Owen on shooting 650 Woodleigh FMJ and he said OK. Thats Buffalo medicine. My Greener had tight chambers designed for the Kynock brass of the day. Ken Owen adjusted my chambers for the modern spec that works with commercial brass.

I’m thinking of shooting a letter to Greener to get all available information on my gun, then have a double gun ‘smith give it a once-over.

Let me know what you find out. I did that. 1897 sovereign action. Only known rifle on that action.

Those are fabulous looking rifles, Dholu........The only Purdey rifles I have ever seen in 577 Exp were regulated for 570 grainers and 180 Fg...........too bad you don't have original case and loading tools/data.......I can only imagine what that beauty cost you.....(Ward, curious markings on your rifle, and, as Pondoro noted, the 650/167Fg loading was the beast loading that Sir Samuel Baker called "the most fatal weapon ever devised) I expect the Purdey load to still have plenty of punch.......well done and welcome....FWB

Flatwater,
Thank you, I measured the chamber length and it appears to be 2 3/4" which threw me as I anticipated 3". I bought some 3 1/4" brass and it slid in most of the way, short by roughly 1/4". Either my measurement is wrong or the taper of the brass allowed it to slide part way up into the lead. I'll cut 1/4" off of the brass and make up a dummy round and see if is still goes in. I have a machining and engineering background so I expect my measurement to be correct, though it won't be the first time I've been wrong. If it is 2 3/4 then I think the regulation might have been with 520 and 560 gr bullets. Thoughts?

Dholupko - Beautiful rifles! and as stated by another member Cal Pappas is a living encyclopedia for such matters; and I believe he is in the process of selling off some of his loading/ammo supplies.
