100 grains of most powders with a bullet of 200 grains MIGHT kick as much as a typical .243

Upping the bullet weight will of course up the recoil (provided all bullets fit the bore equally well). 100 grains of powder beneath a 400 or 500 grain bullet can be quite dramatic.

You will probably wind up shooting a load of 90-110 grains volumetricof powderbeneath a bullet weighing 250 to 300 grains and I don't think you will find recoil to be a major issue. The 300 grain bullet would probably be close to the recoil of an 06.
