Powder Suggestions? 45/70 Sharps Accuracy

[Michael J. Spangler]

Hi guys!

I'm looking for some suggestions please.
I have a Pedersoli Sharps in 45/70 and I'm looking for a nice accuracy load. I would like to narrow down the powders to a few that have known success if possible.
The bullets are the Lyman Postal 535 or a Hoch nose pour 550. I also shoot the lee 405 flat point plain base. Most likely they will be paper patched.

I hear 5744 is good but I can't find it locally. I might need to drive out of state if that's the consensus.

Thank you all.

Any accuracy or pet loads out there?

69 grs. of Olde Eynsford 2f, .030 fiber wad, under a 525 gr money bullet cast from 16-1

for smokeless, with a lyman457132 (casts 520gr for my alloy, not 535gr), I use IMR 4198 25gr. This is about 1178fps, I also have shot Imr 3031 with 31gr which is also about 1180fps. These both shoot pretty accurate at 100yds, anyway. The 405gr, I get the best accuracy with 14gr of Unique. I have also shot the AA5744, but like you said, it is not readily available and it is much more expensive than other powders. I am also shooting a Pedersoli Sharps

For that cal. and bullets like that, I would recommend Swiss 1 1/2fg. a full case, just leave room for the bullet, maybe play a bit with compression.

These were shot at 100 yards. They are my "HOT" loads. For local silhouette matches I cut it back to 23.5 grains.

IMR SR 4759 is nearly impossible to find now. However you've been told correctly that 5744 is a good alternative. I've found that 23.5 grains gave me the same grouping as 4759.

There are a number of places where you can mailorder powder.

Good shooting.

im shooting the RCBS 535 postal and 24.5 grains of 5744 with a WLRP.order some powder from powder valley, i bought a 8lb jug and it shoots great out of my Pedersoli Sharps. i will eventually try black powder.

I use loads very similar to toymakers. 23 to 25 grains of SR4759 until my last big cannister is gone. I use a 500 grain Brooks bullet in numerous Ruger, Browning and Ruger falling blocks.

You cant beat 2400/with 1/2 grain dacron under 350 gr NOE or 405 RCBS ,and yup Unique is great also (never needed anything else) tried lot of others :bigsmyl2:

Rel7, 4198, 5744, and 2400 are all outstanding in my 45-70's. I like Rel7 and 4198 the best.

H or IMR?

H or IMR?

I've got them both and I can't tell the difference. Great results with both. I called H and they said to use the same load data even though I found a couple of loads with different weights given. FWIW, I only load to Trapdoor levels....at the high end though. I try not to make my gun a "varmint gun".

Measure your chamber. Pedersoli sharps have had chambers 1/8" longer than 45-70 brass. 2 solutions.

1 seat your bulet out that far

2 trim 45-90 brass to the chamber length.

[Bill Torzsok]

I have had very good results with H4198 and 405 grain Lee HB around 31-32gr mark.

[washbuster]

I shoot the lee 340 gr behind 29.9 gr H4198.Very accurate at up to 200 yrds..Rifle is Pedersoli Sharps 45/70 with Malcohm Scope.

They've already been listed but I'll be redundant; IMR's 3031 and 4198 and Re-7 hve been the best smokeless powders for me in a variety of 45-70's. There isn't a doubt in my mind Unique and 2400 would also work well but I never tried either in the 45-70.
