What's the "winningest" 45/70 cast boolit?

[guninhand]

I have only one 45/70 mold, the RCBS 330gr FNGC. Based on competition results, what would be the most likely most accurate cast boolit (GC, PB, or PP) for a 1:20 twist barrel with smokeless powder????

Of all designs comonly available, that is not custom the Lyman Postell is hands down the winner followed closely by the Lyman 457125.
This is based on my sales. We offer somewhere arround 35 differant 45 cal rifle designs and the Postell is by far the most popular. Powder choice is irrelavent its still the Postell. There are custom makers producing winning designs but most are slight variations of the postell.

Gun in hand, if you are going to shoot copmpetition, you better find a mold of 500 gr. +. The light bullets won't carry for beans at 1000 yards.

There is no such animal! :coffee: It still depends on your gun. I can't shoot the Postell but my friend's gun loves it. Many boolits won't shoot from many guns worth a darn but shoot from others like gang busters. Welcome to the wonderful world of 45-70's. You will never know until you have every mold made unless you luck into the right one at the start.

Good question from GIH, and the responses so far are good information. I suspect Dan's supply of all those 45 caliber rifle boolits might be a big help to those searching for The Right Boolit without sinking a BUNCH of money into moulds for their rifle.

My use for the 45-70 doesn't involve long-range work, just hunting and getting my aspirations kicked by the Burrito Bandits on Tuesdays. I did learn at Angeles Shooting Ranges this week that the NECG rear sight on the Ruger #1 runs out of elevation at 300 yards or so with both the RCBS 330 FNGC and the Lee 405 sent forth at 1873 velocity levels, and that boolit drop differential between 200 and 300 yards is SUBSTANTIAL. 300 yards is at least half-again further than any game shot I would take with this caliber, so the NECG unit works for my purposes--but it likely wouldn't be a good choice for someone interested in "'way out yonder" recreation.

The Postell design usually casts at 525 to 535 grains, depending on alloy an mould maker. With your 20 inch twist, You probably shouldn't go any heavier (longer) than that...and maybe shorter would be better. NEI has a mould called the Short Postell Gunn which is close to 500 grains. Catalog number is #346C. Looks like this...

Sound advice. I use the 457125 with very good results and see little improvement with the Postell.

My fav. is the Saeco 525 gr. for BPCR, Lyman's Gould HP for deer, and NEI's #446 for bigger game.

I have shot bullshops postel 535 Grn. if my memory is right and I think they are great. On the other hand I have shot the Lyman 405 Grn. plain base and the hollow base and cannot complain on them either. I am not shooting over 300 yards though and that might change if I was to find a place that reached out to 700 or 800 yds.

Thanks for all the input. I have the Pedersoli Mid-range sight for my hi-wall. I'll order samples of the Postell and Lyman bullets and test. I'll never be a big time shooter so there's no point in taking it to too fine a point. I mostly want to beat the locals, with their fancy-pants Browning BPCRs[smilie=1:
