Does anyone know what kind of receiver is used in the (SYC-42S) .22LR / .410 Versa-Pak Combo?
I'm familiar with what the SB1 and SB2 receivers are, and that the "Sportster" receiver is used for rimfire guns. The .22LR / .410 Versa-Pak has a .22LR barrel with and 'off-set' chamber, but strikes the .410 in its certer-primer. This makes me think the 'Versa-Pak Combo' must use an SB1 receiver.
What I am ultimately hoping is that the Versa-Pak .22/.410 indeed uses an SB1 receiver and I can have a low pressure rifle round like a .30-30 or .223R (with its smaller rim) custom fitted to the Versa-Pak's frame.
I of course prefer the more "intense" full-power rounds the SB2 can handle, but it seems the SB1 should be able to handle rounds like the .30-30, .22 Hornet, .357 Magnum, .223 Rem, etc.
Comments please?
