gents:

I have an absolute pile of these on hand. can i use them in my new m70 7mm rem mag with a 26" barrel and a 160 gr bullet?

i'm very curious to learn about this caliber. it sounds very interesting!

what sort of velocity should I expect?

Yes the are the correct ones.

They will work just fine. Velocity will depend on the powder you choose.

thanks. not sure of the powder but thinking 160 gr NPs. what powder then?

jsl, I would start with RL 22 for 160's. Although my real favorite for 160-175gr is Retumbo. Every barrel is different so work up slowly but I get over 3000 in 160gr in a 25" barrel. Good luck with it.

Another vote for RL 22.
