To Pathfinder & other Single Six owners shooting .22 mags.............
OK, guys here's some chronograph info. gathered:
Temp. was aprox. +28 degrees
Ruger Single Six, 5.5" brl., .22 WMR
Federal 50grn JHP - 1087 fps
CCI Speer TNT HP - 1609 fps
P.M.C. 40 grn JSP - 1355 fps
CCI maxi-mag+VJHP-1686 fps
Win.Suprm.34grnJHP-1532 fps
Remington 40grn JSP-1355 fps
Remington 40grn JHP-1261 fps
CCI maxi-mag40grnFMJ-1408 fps
Win.Spr-X 40grn FMJ - 1453 fps
Fed. 30grn SierraJHP- 1609 fps
I can tell you from 'field experience' the CCI TNT HP load is VERY effective on ground squirrel size critters, from my 5 1/2" barrel S.S.!!
(If you have a .22 mag RIFLE, you can probably add 500-600 fps to these velocities!!)
Accuracy varied from pretty dang good to 'shotgun' pattern groups @ 25 yards, find the load that works in YOUR gun.
Hope this helps,
