Thanks for the info! FYI if you ever need to to know muzzle energy, you can figure it out if you know the bullet weight (in grains) and the velocity (in feet per second).
First you take the velocity squared, and then multiple by the bullet weight. Then take that sum and divide by 450400. The final sum is your muzzle energy in ft. lbs.
So for your example of Aguila 38 grain .22lr ammo (assuming it is the Super Extra with 1280 FPS MV):
(1280 x 1280) x 38 = 62,259,200
62,259,200 / 450400 = 138.23
So Aguila 38 grain Super Extra makes 138 ft. lbs. of muzzle energy.
That said, if ME calculations are going to be required for all ammo purchases, I predict wait times are going to really suck at a lot of places.
