Does anyone possibly have load data for the Barnes Triple Shock, 500 gr. out of a 45-70 Siamese Mauser?

Thanks,

Dick Willey

Per Barnes, it's the Triple Shock starts at the max load for their X bullets - I don't have access to a Barnes loading manual and don't even know if they cover a 500 gr. 45-70 out of a Siamese Mauser like my Hornady reloading book does.

Hornaday gives me a max load of 47.6gr. of IMR 4198 behind a 500gr. RN or FMJ RN.

Don't know if I should start with say 45grs. and work my way up to a reasonable load for the Triple Shocks. Any ideas would be sincerely appreciated.

My Barnes #2 reloading manual only covers 45-70 .458" bullets up to 400 gr. - no listing for 500 gr.

Thanks Kdub, If all else fails, I'll try Barnes directly and see if I get a reply.

Ruger & Mauser data. hope this helps you out! as these are only loads for Std projectiles not barnes.

Thanks Dave, I appreciate the information, gives me a starting place.

It's too bad the bullet manufacturers don't offer load data on their web sites like the powder guys do.

Sure make it a lot simpler wouldn't it Michael.
