What is the bullet? What rifle/barrel length?
Is this something new? What does the rifle do with other powders and the same bullets?
When RL22 and 19 came out, I recall Bob Hagel did an article on them in which he stated that in SOME rifles with SOME loads, R19 actually behaved more like R22 as you approached maximum, i.e. . it took as much R19 to produce the same velocity as R22. R19 is of course supposed to be faster during the R22.
Cant say I have ever seen exactly that but I did have a pre 64 M70 FW that handled a couple grains more R19 than the listed maximum with 165 gr bullets just to hit 2900 fps. In fairness this could have been due to the normal differences in barrels, and nothing to do with the powder.
