Pumu-assist Benjamin 392
The Benjamin 392 pump assist is an interesting side street in the hobby.

A history of airguns

This report covers:

  • Crosman Premier
  • RWS Superpoint
  • JSB Exact Jumbo
  • Whadja get?

Today we look at the accuracy of the .22-caliber Benjamin 392 with pump-assist. I tested the rifle at 10 meters off a rest using the open sights that come with the gun.

Crosman Premier

We will begin with Crosman Premier pellets, that I expect to be one of the most accurate in this rifle. Shot one landed high on the bull at 11 o’clock, so I left the sights where they were.

Ten Premiers made a group measuring 0.577-inches at 10 meters. It’s not the best I have ever done at that diostance, but for a 392 it’s acceptable.

RWS Superpoint

Next up were ten RWS Superpoints. This is a pellet I have not tried in a multi-pump, as far as I can remember, so I didn’t know what would happen. Alas — it wasn’t that good. Ten Superpoints landed in a group that measured 1.174-inches. The group is scattered all over the place. Obviously this is not the right pellet for this air rifle.

JSB Exact Jumbo

The final pellet I tested was a JSB Exact Jumbo. This was the pellet I thought might be the most accurate, though to be so it would have to edge out the Premier. Ten pellets made a 0.748-inch group that is ironically shaped like a frown.

JSB Exact Jumbos did not best Crosman Premiers. Ten made this 0.748-inch group at 10 meters.

Are there other pellets the 392 likes even more? Probably. But accuracy isn’t why I own this air rifle. I own it for what it is — a multi-pump that almost was, but never caught a break. A multi-pump that’s easy to pump.

Whadja get?

I’d like to hear about your special Christmas gifts today. Not the socks and sweaters — just the good stuff. Or maybe it wasn’t a gift you got but onw you gave. Please share.

Today’s report is short because I wrote it last Thursday, so I could spend time with my sister who came for Christmas. I still owe you the video of the 392 being pumped, so don’t despair!
