the old 8 bore were regulated for 270 grains of FFg Black powder but the more modern ones were nitro proofed .Is anyone able to tell what load (and type) of modern smokeless powder w'd mimick the power of the 270-300 grains of BP (pyrodex not allowed obviously) Alternatively ,is anyone knowing the smokeless powder load and type able to prop^pel a 1250 grains cast bullet at 1330-1350ft/s in a 26'barrel? thanks and greetings from France |

Thanks ASSASSIN I had just only recently bought some Longshot for its elasticity and some BPI listed lead loadings, and I believe I'll make up some of these high velocity loads as well. I do have on hand the Federal wads you mentioned. I can now see how these high velocity lead loads came into being, as itis my understanding that the 'Longshot' was brought into being as a powder for high speed steel payloads that fill out a large (steel protective type) shot cup at anywhere from 1oz - 1-1/4oz payload. I suppose the thing to educate oneself on would be the difference in 'set back' pressures between steel and lead. If I were to guess, I would think that steel would put out a sharper pressure spike than lead, but nonetheless, I'll look into that, and talk to the folks at Hodgdon before proceeding. I enjoy crow hunting with some buddies, and would love to pull off a 50+ yard kill in their presence before I dish out any info as to the new advantage .. LOL Of course, I'll have a few loaded up for them as well, but only after the fact .. LOL again. Ridge |
