Looks like my new favorite - JSB Heavy .177

[1377x]

the stratton is a very soft pellet.it expands like a hollow point.thats probably why you was having loading issues
i havent used them or the monsters in .177 yet
what do the monsters weigh?
i am putting together a .177 1377 with a 16"barrel.need to find a pellet for it.knowing jsb is is pretty much the best pellet to use,need to find out which one
i had very good luck with the stratton and monster in .22 figured i would start there.i have some crow mags but they look like a shot gun pattern on target still good enough to hunt close range with though
if all else fails will be going with the jsb heavy
