The Sierra manual shows 65.2 gr RL22 for max @ 3100 fps.

If you are getting no pressure signs then why not take it up a notch or two and see what she can do. Imo, there`s no dis-advantage in finding out what your individual rifle`s maximum tolerance capabilities are. It is more a curiosity factor.

From the 65 grains you`ve already used without pressure signs, load up some with 65.2, 65.4, 65.6, 65.8 and so on. Then once you see any small signs of pressure, back off a 1/2 grain and call that your maximum.

Each rifle has its own individual character for load tolerance. Some can`t reach book maximums without seeing pressure signs while others can go over book maximums a little before seeing pressure signs.

Once you establish what your maximum load is using RL22, then play with your seating depths to see what bullet jump distances your rifle prefers for best accuracy for that particular RL22 maximum charge.
