BC 45-70 bullets

[Ammo dog 2311]

I was wondering what you guys and girls shoot out of your BC ? I need to re-supply and not sure what to try next. Have been shooting 47 grains of IMR 4198 with the hornady 300 gr HP at over 2000 (from my crony ) and getting good groups.
So I was thinking of trying something else. Maybe go with cast 400 gr. or maybe heavier? My range goes out to 300 yds and that's it. I am shooting only paper right now so something accurate out to 300 
is what I am trying to find. I put a mid-range tang site on it so I can dial for the distance. So any suggestions ??

I suggest using Rem 405s to see how work for you, but have never heard of a bad 45-70 bullet.

Thanks, Dinny

I have used bullets from both the 350 and 405 Lee moulds with pleasure and success. Cast of wheel weights and a 'dash' of tin to aid mould fillout they have worked fine and are as cheap as you can get. Do the math though, those 405 use a pound of smelted WWt metal noticeably faster. If you buy cast bullets dont get .457 dia, they are too small, even .458 may be iffy. IIRC most of the guys that have tried .459-.460 have liked the results.
The principle at work here is this; a jacketed bullet can function pretty well even if a bit undersize, the strong jacket will grip and spin in the rifling and any gas 'blowby' wont cut or deform the base or up the sides as it goes downbore. Not so, lead; you need to fill that groove dia. so use a bullet as large as possible to fit the fully fire-formed case neck, and thus fill up the all important throat too. ANY gas cutting up the side of a lead bullet, and yes, it even happens on hard cast bullets, WILL destroy accuracy.

Are you going to cast your own, or looking to buy commercial? I have used 3 molds in the past- Lyman 457122 & 457124 - a 330 gr HP, 385 gr RNFB, and a Lee 500gr pointed which comes out of my mold @ 475 gr with my alloy, also a FB. All of mine are used from 1250-1550 fps. You can use the IMR 4198 with them also- I use 33 gr with the 330, 30 gr with the 385, 28 to 32 gr with the 475 gr.

I want to buy commercial for now. Goin to start buying casting components soon. Probably start with a bottom pour furnace and get the rest as I go.
Was looking on some of the cast bullet web sites, lots of options out there. Not sure what to get. Can you help me with this. Want to get some in the 300 gr and 400 gr weights. I saw some that were cheap and some were expensive. Don't want to spend a lot to put holes in paper but do want accuracy. Don't want to sound cheep but I have a lot of money tied up in a custom 300 win mag and a custom 338 lapua mag that are being built for me by Andy of AD arms. He's a great gunsmith but don't call him till he's done with mine first LOL. So money is not the driving force in my selection but don't want to waste it on bullets that kill. Just medium range target ammo.

I use the Oregon Trail 405 FP with very good accuracy.Load is mild 32grs IMR4198.Fun to shoot, mild recoil.They are available from Midway and other sources as well.
Good Luck]
