I have both rifles available to shoot.  Both are 1-10" twist.  I would appreciate any help with loads for the rifles.  Please advise me of bullets used and loads.  Thanks for your help.

Look at the pressure lelvels, these are higher velocity loadings.

I found the smaller diameter bullets shot better at 1800fpds to 2,000 fps than 7mm amd .30 caliber bullets.
