HW/Weihrauch Pellet Weight for Beeman R7

I think you mean 7.33. Those and the sister pellet, JSB RS 7.33s usually work great in most R7/Hw30 guns. The accuracy with the JSB branding of the same 7.33 pellets can sometimes vary between tins. The Falcons are almost always great. It's worth the extra couple of bucks for the AA of you can afford it.
I've had the same experience - the AA Falcon is consistently excellent while its JSB sister design can vary. It's become a fave for my R7 and P1.

To expand on the notes above re: pellet fit, I've found the 7.3 Falcons are faster at the muzzle than the 6.9 gr RWS Hobby in many guns. The latter has a thicker, stiffer, and slightly larger-diameter skirt than the former.
