The load is 40 gr./4350. 50 or 55 gr. bullet, doesn't matter.
I have no idea how much 4350 I have burned up in 22-250s over the years I have been pd shooting, but it is a bunch. For several years before the last plague, I was "budgeting" for 16 lbs, just through my 22-250.
This is an excellent load. You can't really overfill the case if you are shooting 50-55 gr. bullets. If the case is new, you will only be able to get about 39.5 gr. in it. Once the case is fired and if you only neck size after that, you can get 40 in it. As Jack said, a drop tube will help.
I wouldn't recommend this, but one year on a pd trip, I took my press, powder and bullets with me. I reprimed some 22-250 cases, poured in the 4350 until it hit the top, shook the top kernels off so I could start the bullet,and then seated it. Neither the pds or I could tell the difference.
It may not be the hottest load, but for accuracy, I have not found any powder that will beat it. The accuracy benchmark for at least 20 different rifles was established using 4350.
I am using CCI BR 2 primers, but you will get good accuracy with just about any.
