I'm going to work up a load for my 7 mag. Using Barnes 145 LRX and RL22 powder.

Barnes page says RL22 is the best powder for the bullet and max is 65.3

Alliant doesn't have the exact bullet but using a different 145 gr it recommends 68gr as max.

I'm going to work up my load using Barnes info because its lower but should I expect to have to load all the way up to 68gr? that's

about 5% over barnes max. Seems significant.
 
When shooting big stuff from bench never hurts to add padding ^^^or lead shotbag between you and rifle. Also remember you are not going to die from recoil, but quit before it gets to be too much. Some of my bigger stuff I have a 5 shot rule and put them away for the day.

Luckily your in the right place. We will peer pressure the crap out of you. Just rebarrel your 7mm with a proof and put a reputable break, or better yet a suppressor, on your new barrel. Eventually you’ll decide you need to spend about 5k on your setup. The good news is there’s a lot out there to get you shooting a long ways pretty comfortably. I shoot a 338 lapua and I can go have a 100 round day, no problem. The only thing that hurts is my wallet.

I won't take much convincing. My original plans for this rifle were a proof barrel in 6.5prc and a carbon fiber stock. It will probably still happen. I want to get a few hunts under my belt before I decide.

Should be a magic spot right around 63gr with RL22 and the 145LRX.... I used Barnes data as my benchmark when I use Barnes bullets. Hornady for Hornady, Sierra for Sierra, etc.
 
I could have used it. I put 30 rnds down range today. I had to fold up a rifle sock and stuff it in my shirt after 10 rnds. My shoulder was killing me. I think I found a load. I'm going to mess with seating depth next. I had 1 outlier in the chrono data. If it was a4 shoot group sd would have been 3.4 and es of 9. So im going to try and work with that. I have to think that the horizontal dispersion is shooter induced. These were shots 26-30.
