1968 H&R topper 158 to rifled slug ned help

[kingdombuilder]

I know honing big bore did this before but not on older guns. I also know i can use the old barrel as a stub then attach a new barrel to it. My question is who will do this type work i live on long island shotgun only county. HBB charges 500 plus for a barrel for tc guns. They had gun smith on website but now i cant find info. My cuttent barrel is full choke. Can it be rifled?  I also want a muzzle loader but i have a store selling Tc impact for $ 229.00 some wisdom and knowledge would be appreciate  ps  dint circle my spelling errors with a red pen thanks.

Sorry forgot to say its a .410 diameter or 67 gague :-)

Welcome!

If I understand correctly I'm sure the barrel could be rifled... BUT would not do you much good it's too large while it might impart some rotation to a foster slug it would likely be useless on a sabot.

Smooth bore shotguns can really shoot well. A lot of the INaccueacy is from the poor sights on most smooth bores...

Gun smithing these guns is cost prohibitive. They sinoly ain't "worth" investing such dollars in. You really need to be able to either do this yourself or barter with someone who can.

This would be a hunting gun for me worth for me is accuracy. If i can get moa out of this its a done deal. I heard of barrel stubbing bu i have no refrences or review on outcomes.

Just buy a used rifled slug barrel for it and fit it yourself, modern H&R/NEF barrels will can be fitted to the M158 frame. You just missed one in the H&R Classifieds, barrel fitting info in the FAQs sticky.

If you must stay with 410, A fully rifled tru .410 bore WOULD be a custom. BUT there isn't many sabot 410's out there to take full advantage. So you actually are likely to find a smooth bore more accurate. BECAUSE all there is, is foster style slugs.

You could try a 45/410, BUT that's a .452 rifled bore, .410s foster slugs are smaller dia .406-.411 IIRC.

Most .410 barrel's are a full choke...that's NOT the best choke for accuracy from a slug OR Buck shot. Doing something like a few of us have done here. Get another 410 barrel and have rifle sites installed after chopping off a couple inches of barrel to eliminate the choke.

kingdom,

Last time I checked with HBB they where only making the rifled 410 barrel for T/C Encores.  HBB did make a couple of H&R rifled 410s, I had a chance to buy one and didn't , but I haven't see one listed for sale in 4 or 5 years.  IF, you have a rifling cut in a smoothbore 410 you are going to have a groove diameter of .416 to .420 inch which is way oversize for any 410 factory slug that I know about.  The fosters will "bump up" when shot but I don't know what can of accuracy you would have plus the barrel leading issue.  IMO, you will have to handload your own 410 slugs if you want to take advantage of a rifled 410 barrel.  If you use plastic hulls and need a bullet of say .42" diameter, then you may need to neck ream the hull to chamber the round.  If you use all brass 410 hulls from RMC then you can spec your hull ID and eliminate the neck turning issue.  Magtech sells cheaper 410 brass hulls but I don't know the dimensions of their hulls.


Good luck with your project.

This place makes them for T/C's but they're pricey:

They also make heavy 410 slugs.

Sounds like a pricey thing to do to a "budget" gun. I'd do as someone else suggested above and get a 20ga with a rifled barrel and rifle sights.  Readily available and with a better ammo selection.

Or at least pick up a rifled 20ga barrel so you will have both options available.


Or, if you're dead set on keeping you current gun, you might want to contact Mike Orlen [size=78%]http://users.dls.net/~rdouglas/MikeOrlen.pdf[/size] and see if he can set you up with a removable rifled choke tube.  He's reasonably priced and has a good reputation.


But, as someone else also mentioned above, decent sights instead of a bead will likely make a bigger difference than a rifled bore with a bead sight.   A smooth bore with decent slugs and sights can do a pretty decent job, but IMO, MOA accuracy is asking a bit much for a slug gun in most cases.


As far as converting to a muzzle loader, check these out:  [/size][size=78%]http://www.gunadapters.com/410-to-209-muzzle-loading-adapter-1/[/size]  They make them for 12, 20, and .410.  Not a bad price either.


Just some ideas....

I have a hard enough time getting MOA out of my rifle barrels.  As stated I would simply put rifle sights on it, remove enough barrel to clear the choke and hunt with it.  I'm always on the lookout for a Tracker 1 barrel to have the sights and the smooth bore for shot.
