I have copied info from another site where the -87/.22 was chronographed. i hope you find it useful.

I was able to get more numbers tonight and I don't think there is anything wrong with the gun.

For whatever reason, the JSB's were shooting hotter for the first few shots last time. After shooting tonight, the 794.9 - 770's had to have been a fluke for the JSB jumbo pellets.

CPHP 14.3 JSB 15.8
845.2 743.9
848.1 750.6
852.8 720.7
853.3 750.9
854.8 757.7
848.1 749.4
852.0 750.2
848.3 751.2
849.9 756.2
851.2 741.8
851.0 753.5
851.2 734.1
853.6 739.1
855.1 749.0
857.5 748.3

This was shooting as fast as I could load.
I did notice that the JSBs do not fit as snug.

(I see that the numbers did not copy correctly to this page, but you can see how the two pellets compare. if you want the web link,let me know.)

Also, read these reviews from Compasseco ( I just bought one in .22, and like it, but it's heavy; a manly-man rifle). Page down to see Chrony numbers for the .177. Good luck!

Close enough.

I haven't chronographed mine yet.

It's still new,and still smoking. hey, maybe it's tossing the 14.3gr CPHPs at over 900fps! when it settles down I hope to haev numbers like those posted, or close enough.

Pretty good power. 36 fps spread on those JSB's don't

look so good though. Wonder what the difference is between them and the Crossmans? The crossmans seem very close compared to the Jsb. Thanks for sharing. jmag

My guess

September 2 2010, 3:04 PM 

JSB's are notorious for having dings in the skirts right out of the tin. Therefore a couple of "leaky" JSB's could be the reason for the extreme spread. The Crosman Premier Hollow Points are made from harder alloy, and they are very consistent in all of my guns. My guess is that the skirts don't vary much at all and don't get bent easily.

I have been very disappointed with JSB's and have lots of tins of them that just sit there on the shelf. The CPHP's on the other hand get shot. I just came in from shooting them in my Marauder at 50 yards. Great pellet for $6.95 per 500 at WalMart.

what?!!

September 2 2010, 7:21 PM 

You paid only $6.95 for a tin of CPHPs? I had to pay $6.97 for a tin. Life just ain't fair! happy.gif But my rifles like them as well, so I won't cry over being ripped off. :D

optics?

September 3 2010, 2:12 PM 

what scopes are you guys using? I've got the Leapers 3x9x32mm Bug Buster on an Accushot offset scope mount. I drilled my receiver to accommodate the two scope stops in the mount. I got it to save a little weight, and the magnification suits my needs. The killer is that I can shoot inside with this scope because it has a parallax minimum of 3 yards. Now to go apply new loctite.
