I have some questions about using Briley subgauge tubes in a 12 ga. Parker

[Bob Jurewicz]

I have a 12 GA Parker DH with 2 1/2" chambers that I fit with a set of Briley Universal 20 GA tubes meant for 2 3/4" chamber. A little careful grinding at the forward end of the Briley chamber area and final polishing. They work great. I don't know why you couldn't do the same with 28 or 410 GA tubes.

If I’m not mistaken Briley will sell you the shorty tubes that require no messing with chambers or forcing cones and I believe a three gauge set of those cost around $900 new . https://www.briley.com/c-467-side-ki...tube-sets.aspx

Just a word about the Briley Side-Kicks. These were my first exposure to sub-gauge tubes and since they are short and not fitted to the gun's bore diameter there is a large amount of burnt powder residue that comes back between the tubes and the barrel, even though there is an O ring on the end of each tube. You will be doing a lot of heavy cleaning between shooting the different gauges. And then when you're done you will be doing a lot of heavy cleaning to the tubes themselves. They do work okay other than that. Really, the full-length drop-in tubes are the way to go, especially if you're just doing one gauge.

I used a set of the short ones a friend had . The 20’s were a skoosh longer than the chamber , the 28’s a bit more and the 410’s about as long as what’s available now . And I never had a problem with unburied powder .

Read the rules for sub gauge tubes. Some side by side shoots allow sub gauge tubes only in composite barrel guns. I think the Southern may be one of those shoots.

Of course, I said burnt powder Craig.

I do not differentiate between the two when it comes to cleaning and or removing insert tubes . The biggest problem I ever heard of were some skeet shooters that had ported the barrels as well as the 20 and 28 gauge tubes . They would be a bitch to get out , but I never saw the need for ported 20 or 28 tubes in typically a 9 pound tubed skeet gun .
