Hi I am new to this site and was wondering if anyone had any modern loading data for this cartridge. The gun was built in the 60s on a model 70 action . The barrel measures 29 1/4''long. I am not sure on the twist. Any info would be appreciated.THANK YOU

I have some, but not with me at the moment.

It shot well, the only problem I had was, I was not able to find a resizing die that was exactly right ( in the shoulder area) and after about 2-3 shots the brass was at the point that it wouldn't chamber very well.

I used H-1000 for the most part.

Finally found my notes.

This is a 1:12 twist 26 inch barrel with a Neiska action

108gr lupa 75gr RL22 3507fps
108gr lupa 80gr RL22 no data best group 3 shots touching hot load

100gr nosler 75gr RL22 3532fps

120gr nosler 80gr H-1000 3250fps
120gr nosler 72gr RL22 3300fps

After playing with this for a bit I had the gun re-barrelled to a 264 win mag with a 26 inch barrel and a 1:8 twist to shoot the 142gr sierra.
