jas,
any bp load would minimally start at roughly a full case, drop tubed of course. From there, you may wish to go up additionally while compressing the powder. Compresson on a case of that size could easily be as great as 3/8 of an inch but smaller is probably more accurate. I would completely forget about the book in this case. BP is not so standardized that you can assume that a 135 gr load from company X in granulation Y from yesteryear is anything like a 135 gr load of powder brand A in granulation B being made today.
BP specialized lube on the bullets and card wads on the base are standard protocol. You will want to learn about blow tubing or wiping between shots.
If you want to go with paper patched bullets, I'd be happy to help. They have a few other issues to consider.
There are a number of places on the net that have copious numbers of well educated bp cartridge riflemen. The
http://www.bpcr.net forum, Shiloh Sharps company forum, the ASSRA forum, and MSN's BPCR forum are just a few.
