Umarex Prymex - MV unknown

[twiki]

Just got one in 177 for $130 at Cabela’s.
Box says 1,200 fps blah…blah.

I don’t have a chrono, but what kind of MV can I expect with something like Stoeger X-Hunt 8.6 grain pellets?
7.9 grain CPHP reportedly shoots well in this gun too.

For now, I have put RWS 8.2 grain SuperPoint, and 7.7 grain R10 wadcutters through it, and it’s a little loud. Can’t tell if it’s supersonic, or just still dieseling.

I’m in a residential area in Edmonton, so backyard shooting is a no-no.


Thanks.

Probably 850-900..

Youll find heavier pellets will be more accurate and decrease the report considereably. The only way to really know MV is with some type of chrony and not just guessing.

A lot of these ultra high advertised velocities are with alloy pellets not lead.

PBA raptors are usually the fave and if your shooting ten or fifteen feet they may be okay but at any distance theyve sucked out of any gun Ive tried.

Just curious to know if it was dieseling and the noise dropped back some. I recently bought the .22 version and only fired 1 shot through it and it was loud. Sounded like a .22 rimfire. Hoping that was dieseling as I watched several videos about the gun before buying and reviewers found it reasonable quiet.
