Can anyone point me to an online source for 350JSP 45-70 loads using 3031?

My Lee manual has data for 300's & 405's, but no 350's?? Guess I could just look to the middle ground....

Recently turned in a 0.75" group @ 100 w/ my #1 using the following load:
Cast Performance 405GC / 47.0 IMR3031 / Starline Brass / Fed Lg Rifle Match primers

Tried 45.0 & 49.0, but the 47.0 was the ticket. For the record, these loads were 2.0 grains reduced from published data because of the Starline thing...

Any input welcomed. Thanks in advance!

I don't have the manual myself, but had somewhere a couple of copied pages from somebody else's that showed specifically load data for No. 1 and 3 rifles since they can take higher pressures than the lever guns. I have a load that seems good in my No. 3 but have never chrono'd or done grouping. just know from what it does on the shoulder that it would work if I ever hunted with it. of course I save these rounds for when I am having fun. :-)

I'd say look around for a loading book that has the seperate data for the Rugers.

I've note the separate sections. Personally, I'm most interested in accuracy & effectivness on game in this area. Deer & hogs mostly. Couple of large exotics on some of the ranches, but I feel that the 405 load detailed above would fill the bill - at a realistic range.

Guess if I was headed for grizzley country, I might be a bit more motivated to explore catagory #3.

Thanks for your input, but if you don't mind, an additional question: The current buzz dictates using 2.0 grains less for any given 45-70 load using Starline. What is your take on that?

My feelings are the same regardless of the firearm used or the components selected...

Start near the lower end and work-up gradually until either the level of performance you desire is reached, or the first sign of excessive pressure is reached. Naturally you should stop at whichever comes first.

Bullet Type Bullet Weight Bullet Diameter C.O.L. Net Water Capacity Powder Type Charge Primer Type Muzzle Velocity Muzzle Energy Group Size
Hornady RN 350 .458" 2.550" 58.6 IMR 3031 56.8 CCI 200 2065 3315 1.2

Should be able to adapt the 350 grain RN loads to the 350 grain FN.

Gents -
Very much obliged for the input. Any thoughts on the load density / accuracy relationship w/ this powder in 45-70?

My best results w/ the 405 load were with a full (but not compressed) case.
