MSP Ret
Andy, I had a Versa Pak about a year ago and experimented moving barrels around.
http://www.graybeardoutdoors.com/phpbb2/viewtopic.php?p=288588&highlight=#288588What I found was that the .22 VP barrel would fit on a 30/30 Topper frame, and a 30/30 SB2 frame, but there was a rather noticeable gap. The .410 barrel fit also, with a gap. But that could just be the way those particular frames were with non-fitted barrels. (Note that the barrel off the Topper 30/30 and the one of the SB2 30/30 didn't fit each other's frames either!)
I believe both VP barrels (22 and 410)
should work if they are installed on a properly fit centerfire frame because of the offset of the rimfire barrel. The 410 of course is already centerfire.
And FYI the .22 VP barrel, though it did fit on my .22 Sportster very well, because of the offset, the rimfire firing pin on the Sportster hit in the center of the .22 case with the VP barrel on it. It did not fire a round while on the Sportster.
Therefore the answer to your question:
OK guys, I'm trying to follow this. Does this mean if we have a Pardner or Topper .410 barrel that fits correctly on our Sportster frame that the Sportster firing pin will be centered on the .410 shell primer and we could shoot that .410 barrel off the Sportster reciever?
is a definite maybe! The Sportster firing pin is centered on the .22 offset barrel, not the .410 barrel ... so the answer depends on the diameter of the 410 primer.
If the .410 primer is the same or larger than the diameter of a .22 rim, the firing pin on the Sportster will hit it somewhere.. however if it just hits near the edge of the 410, will it be enough to set it off??? :!:
Got some primed .410 hulls to experiment with?
Wait a minute... :idea: ... if that works, does it mean you could shoot .45s in the .410 barrel on the Sportster??? Yikes.. this is getting weird! :shock: :shock:
Maybe you should tie it to a tree with a long string, like you suggested to the guy asking about the 444 in the 44 mag. :wink:
Cheers
