Opinion: Purchasing bulk 22LR ammo is basically playing three card monty with ammo manufacturers.
The first thing we know is that the lot number is a Federal lot number, not a CCI number (if that matters).
The second thing is that Federal's website does not even advertise #790.
The third thing is that Federal has made 22LR ammo specifically for WM.
It would not be a surprise if it was the same #745 in a new box. In regard to quality, it will be difficult to discern differences in bottom of the line products, without chrono'ing 50 each and also seeing the spread on the target. Are the charges consistent? Are the bullet heels deformed? It is both velocity consistency and how they fly.
Is #790 better than #745 or the BYOB packs? It is possible that #790 is the #745 that does not meet some minimum quality standard. It is also possible that it is the exact same thing in a different box since #745 is no longer a WM exclusive.
It will just have to be tested. I may have to get a box to try. For comparison, my rolling 5 shot average at 50 yds with #745 is 1.608", whereas #510 is 1.199", and AM-22 is 1.386". (#710 and GB are over 2".)
It's odd, that Rem. Golden Bullet is near-perfect in the M&P, but most types of Federal have freq. malfunctions?
The Golden Bullet profile is basically a round nose with a HP. The low end Federal ammo has a truncated cone bullet profile. A lot of times, 22LR handguns made in the image of the centerfire counterparts (or practice kits for that matter) have to have such a steep feed ramp that the TC profile has more failure to feeds. Switching to a RN profile (which GB's basically have, like #510 or AM22) feeds better in those handguns.
