7PRC 145 and 160 Barnes load help

[Pronghunter]

Anyone have any data they could share.
22” barrel here. 1:8

I have 300~400 rounds of 145 and 160 Barnes LRX so I’d like to shoot the up.
I have H1000, Retumbo, N560, N565, N570 powder.
A little lost on what to run with the shorter barrel and lighter 145’s for burn rate as well as the 160’s. I’ve done lots of looking. I even went on Barnes website. It’s not that I can’t figure out the charge weights or powder options, I’m trying to figure out what powder would be the better to start with. I’m sure I can locate other powders as well. Just trying to figure out if I should stick with H 1000 with the heaviest and what I should run with the lighter.

My brother has the Ruger American GoWild rifle in 7PRC and with limited testing the gun was accurate with 145 LRX and IMR7828SSC. I don't have notes on charge weights or resulting velocity, just my recollection of results on paper. I'm sure I used Barnes data as a starting point tho...

RL 23 gave me significant velocity in a 21" over H1000 shooting 145s, if you're able to find any. Settled at 3130fps with great accuracy
