Hello,

Anyone have a pet load for this combo?

I have loaded this using RL-17, and worked up to 58.0 grains that produced under 1 inch group from a model 100 Winchester. I think this is getting a little hot for that old gun.

Why doesn't Nosler produce some load data using Reloader 17 for this cartridge??? :(

Thanks, Mark

Hello,

Is this info from a load manual or is this a guide from Quick Load?

Thanks,

It's only a Quickload guide with rough estimations of pressure and speed, do not use this as a reloading manual.
