Polychoke and tss

[hunter85]

Does anyone know if it is safe or can be/ have been shooting tss through a polychoke. I have a Sears semi 20 that has had the barrel cut to 18 inches and a polychoke installed that I'm looking to gift to my granddaughter.

I'd never be handing it to my daughters and saying here go see if this is safe. Don't chance it. Buy her a new gun

Oh I would definitely be shooting it first before I ever gave it to an 8 year old! Figured I would ask before looking into having it removed and threaded.

[Bowguy]

Don't take my word as absolute but that's an old gun and set up. I'd just not chance it when guns are so cheap many times. I mean at 8 years old she needs a youth gun anyhow. Gun should fit her.

The gun is a Sears M300 branded Winchester 1400 semi-auto that had been cut to youth lengths 13.5 lop back before they marketed youth size guns I also have a Springfield 840 30-30 that I plan on gifting her as they were the first guns bigger than a .22 is the reasoning behind asking this question. And I have no issues having the barrel threaded just also see no need in spending that money if it's not needed.

The gun isn't that old and will handle any turkey load except maybe nitrous just fine.  As far as the poly choke, have a gunsmith look at it and see what he says. If not set too tight I'm sure it would be fine as well, there's just the possibility of accidentally tightening it too much and blowing it out with tss as is can "slug" due to being so dense and hard.

So shoot lead ammo in it instead of tss? Lead ammo will kill a turkey just fine at normal turkey hunting ranges.

Having a barrel threaded though costs money. That same money for a thread job and choke might need to be considered against the low cost of another new gun already set up.
