I usually load RL22 under 160 gr Nosler Partitions for my 7mm Mags. Most rifles grouping starts to go south when the barrel gets hot. - dan
With my Sendero 7 Rem mag I pick a bullet, put in some powder off Hodgdons reloading site, and shoot, it always shoots 1" or better.My go too load is 168 Berger VLD's and Retumbo, start low and work up. what are you trying now? what are you getting for groups? what are using for a rest? what type of scope are you using? there are a lot of variables, way more than listed it's not always in the reloading.
How many grains Rl22 with the 160's I'm trying some tomorrow with 61 gr.
