I bought the 28.5 domed and 32.4 pointed pellets to try in my 392PA . They are branded Seneca now but are the same as the old Eunjin brand .
I had better results with the 28.5 . Oddly enough they made slightly more FPE than the 32 grain in both of my 392’s. Don’t know why ?
The domed ones are as accurate as any pellets I have tried. Maybe the best.
I shot the GTA 30 yard target with one of my 392’s. Looks like a 173 score. I thought that was pretty fair for a 392 type gun novice. Room for improvement.
These pellets are oversize to just fit the larger 392 bore.
Sure did make some power at 657 fps for 27 fpe on 8 pumps.

That’s some serious power from a pumper! Nice!
That’s exactly what i’m hoping for ( 26 to 30 ft. lbs. from 28 to 30 gr. Pellets or slugs) once my 392 gets back from steroid treatment. :D

You should be right around there. The 28 grain is more accurate and makes more power for me. I don’t think a stock 392 has enough power to use these.

Several years ago I saw a post ( somewhere) showing “I think” 495 FPS. With a stock 392 and a 28 gr. Eun Jin. chronoed.
It’s amazing to me what some of you guys can make these pumpers do.
I’ll probably shoot my steroid on 6 pumps most of the time, but you can bet i’ll be finding out what it will do on top end with heavy pellets. :D
Btw,
Is the trajectory of the heavy pellets at max pumps anywhere near the trajectory of say a 14.3 or 16 gr. Pellet at 25 to 30 yds. On lesser pumps of around say 6 to 8 pumps in your 392 with the rifle sighted in for the lighter pellets?

It was sighted in for 15.9 jsb at 6 pumps. The point of aim vertically was very close but to the left with eunjin. There may be something to this left , I need to investigate more. Possibly cant the scope to compensate.
I the end, I will put this gun back on the lighter pellets at 5 pumps or so and use the Eunjin in my other higher power 392.
For your new Steroid, I think I would always pump it 8 or more.

Charles, not only do the 28 & 32g Eun Jins work great in my RS-I, but also in my Steroided 342 & stock 342. Like Timmy McMurray said a while back, "Heavy & slow."

Thanks Charles!
I was hoping the trajectories would be close doing it that way.
That’s one of the advantages with a msp to me.
Can’t wait to get mine back🙂!
