Right now i’m Using the Noe 20 gr. pellets on 10 pumps from my 392 steroid.I also shoot crosman 14.3 gr. domes from the same rifle on 8 pumps.The 20 gr. pellets at 10 pumps give the same trajectory at 20 to 35 yds. as the 14.3 gr. pellets do at 8 pumps... so no Change to the scope settings when switching between the different pellet weights for general small game hunting.I plan on using the 20 gr. Noe’s with my stock 392 exclusively once I fix the pump linkage on it.
The 20 gr. Noe is a pellet, not a slug. On 6 pumps from my steroid 392 I get an avg. of 588.9 FPS. at the muzzle for 15.4 ft. lbs.The skirt is .220 and the head is .215”.I know 6 pumps with my 14.3 gr. pellets shoot the same velocity from my steroid as 8 pumps with my stock 392.I have’t tried the 20 gr. pellets in my stock gun yet though, but the velocity on 8 pumps from it “should” be close to the 6 pumps on the steroid.
Oops,Made a mistake on the Noe 20 gr. hunter pellet.It’s .217” on the head portion....still .220” on the skirt though.Sorry about that!
I’ve heard the 392’s described as old English specs..220 bore and .217” on the lands..... don’t know if that’s true or not as i’m somewhat ashamed to say i’ve never slugged my 392 bore.I need to do that.I do know these Noe pellets shoot as well as any jsb pellets i’ve tried... and that’s saying something.At least they do after I visual and weight sort them.The most the noe’s vary is .5 gr. with about 80% being 20.2 to 20.3 gr.It’s really a waste of time weighing them for general shooting.Heck, the last batch of jsb’s I weighed varied the same .5 gr. in weight...same with crosman premiere domes!
