I have shot a 140 gr. bullet in my 7 mags for years for deer size game with very good results. I have a few boxes of 162 gr. interlocks on the bench that I bought before things got out of hand with shooting supplies so I decided to work up a load for one of my rifles with this bullet. I also have a couple cans of RL 22 that I don't use much so I decided to use this as my powder. I loaded 62.0 gr RL-22 behind this bullet and it grouped under 1 inch at 100 yards and had no over pressure signs. I had a limited time to shoot today so I did not set up my conograph. My question is how fast do I need this bullet moving to give good results on deer size game. I will shoot again in a few days and check the speed of my bullet and post the results. I have not hunted with a bullet this heavy in a 7 mag and was just wondering what speed I need with this bullet for it to perform well.
