Author Topic: .410 Choke Help (Read 1731 times)

I am not a gunsmith and need some advice from the experienced minds. I am getting a .410 that has a cylinder bore - I would like to change this to a full choke. What is the most cost-effective way to change the choke on a small barrel like a .410?

Can the barrel be reamed out and a choke tube soldered in place?

Thanks for any advice.

That process is called sleeving and yes it can be done. One could also create a 'jug' choke' in the barrel by reaming the bore to a larger diameter inside the barrel with the last couple of inches of the bore remaining the original diameter. The effect is the same as any normal choke. There is also the choke tube option although that may be the most difficult to find a smith to execute. Lastly there is a process, pretty much out of favor called 'swaging' where the end of the barrel is literally swaged or forged to a small diameter. There is tooling available for this process also. It cannot usually be done on a ribbed barrel. Good luck.

Jim unless you have an expensive .410 bore or it is a keepsake, it may not be economical to do anything to change the choke. But there are some places that will install a choke tube www.trulockchokes.com is one place that advertises they will work on .410 bore. Briley is another. Swaging the barrel is probably out of the question since the bore will have to be constricted .032". If you have a lathe or know a machinist who likes to piddle with things like this, a choke tube could be made to fit the outside of the barrel and then either threaded on or soft soldiered in place. much like the old poly choke. look at the Trulock home page for some information on about choke tubes and installation.

Longgun, .032 would be the difference in a 12 Ga. but not a .410. The difference in a .410 is only .015, .395 is full choke in a .410 and because it's .410 bore cylinder is .410

Jim B. I had a Brng. reproduction mod. 42 Win choke tubed by Mike Orlen from Mass. Very reasonable. His current pricelist states $55 per bbl. plus the price of the tubes and shipping. His turnaround is 1 to 2 days on bbl work. I sent mine and had it back in 6 days total time. The deciding factor is the outside dia. of the bbl.

why not do the old poly choke?

putting a thread on the outside of the barrel and putting a choke on that way would seem to be easiest.

oops, sorry, did not see the reference to the poly choke already made. seems we have some very intelligent people here already

Thanks everyone for the helpful advice.

Since I am interested in preserving the external appearance of the barrel and am not interested in swapping out choke tubes the processes of "sleeving" and "jugging" sound like the most practical options.

Of these two options, which would be the most effective (I assume sleeving)? If jugging is significantly less expensive and the results a significant improvement over cylinder bore (though not quite full choke) that option may be preferable.

Does anyone know smiths who do these procedures? Any opinions on which of these are best would be appreciated!

Back in the 60's or 70's the Russian trap shooters came to the olympics with a secret weapon, they had a 'new' choke methodology. They were using the jug choke which had been invented as a way of giving muzzleloaders chokes without making loading from the muzzle, impossible. It's a fairly simple process and is easier than sleeving. I can also vouch for Mike Orlen. I've dealt with him in the past and found him an impeccable smith and a gentleman to boot.

Drop the www. and treat what remains as an email address. Send an email to this address requesting a price list and he send a PDF price list to your email..
