andy, i remeber sometime back when J3 wasa lil'fella.... he done sumthin like that witha
sportster barrel, i think...
.
ona sb1 an used gamo platinum pba armor pellets with nobelsport 209 primers....
i still gottum from that era....
i jus hadta go look at'um
he wittel'd downa wood dowel un til it fit jus rite inside tha skirt for positioning tha pellet
like he wanted...... he liked tha outcome, and said... its better in accuracy than-tha 22lr
option.......
and he never hada skirt separate with his technique
never thought about any dangers cuz tha primers, of course... only produce minor pressures cord'n to piezo testing that we performed.
the outcome is simular to tha results most have with standard colibries.
