I don't buy Rem primers because of the cost - about $200/5000, where as Cheddites and CCI are 117/5000, Win are 130/5000, and Fed are 140/5000. Same for factory wads- about double the cost of ClayBusters. The CBer wads usually have lower pressures if that's what you're going for. With a CB 1100 wad, Win primer, 1oz of shot and American Select powder you get 1200fps at 6900psi. In my 2006 IMR manual they don't show 4756 for any 1 or 1 1/8oz load. With 7625 it doesn't matter what primer or wad - Win, Fed, or Rem, all loads are under 7000psi at 1200fps. I don't see a CCI primer reload in the IMR book. In the Alliant book they show just a couple of loads with CCI's and the pressures are the same as with Win primers. I load mostly 3/4 and some 7/8oz loads so the powders I listed were for them. I see with a 1 or 1 1/8oz load pressures are up a bit, but as long as they're under 8000psi I'm happy. If less recoil is what you're after, reduce the shot. Pressure is not in the recoil formula - velocity squared times the weight of shot, wad, and the powder is in the formula. I think if you do a little research you'll find CCI,Win, Rem, and Cheddite primers all have about the same pressures. I may buy CCI primers next time I order. Some shooters have complained about Cheddites piercing. And the CCIs are made in the USA.
