H&R Handi Rifle, and the NEF 410 Shotgun

[challenger_i]

Can One use the NEF 410 bore shotgun to build a Handi Gun rifle?
I sent a message to H&R, but no answer...

It depends on the size of the firing pin. If your 410 has the fat shotgun firing pin, its best to just leave it as a shotgun. If your receiver has the smaller "rifle" firing pin, the it can be safely used for building a rifle, with over 50 different low pressure cartridges that would be safe on that type of frame....

If you want to get a NEW Handi barrel you better hurry. They are closing down there barrel program as of 1/1/15

The .410 is a shotgun (iron) frame and would only be suitable for low pressure cartridges such as the .357 or .44M. Get yourself an SB2 frame and eliminate possible problems. GW

Or, get a .357 mag and be one of a lot of happy campers.

The 2 barrels and the action would easily slip into a back pack or bag, go anywhere, and take most small game and deer.

If you want to go bigger than deer then I'd look into reaming to .357 max, and learn to keep your distances on the shorter side.

Reason I ask is, I already have the NEF shotgun. Was thinking about getting a Handi Rifle, the thought "Well, duh!" So I figured I'd see if mine would work.

So, if I have the right firing pin, would 223 Remington work?

The shotguns came with the SB1 frame, which is a weaker frame then the rifle frame, or SB2 frame. It is both a firing pin and a frame strength issue. Here's the problem, at least sometimes. The shotgun frame isn't made to handle the higher pressure rifle calibers, regardless of firing pin size, but can handle the low(er) pressure calibers like .357 and .44Mag. If you have the large firing pin, it works great for shotgun shells, but sometimes allows the primers to flow into the firing pin hole if used with .357 or .44, at least for some shooters. Now if you have the small firing pin hole, it works great for .357 and .44, but some shooters have reported pierced primers when firing shotgun shells. I have both, and my .44 fits perfectly on both my small hole SB1 and my large hole SB1, and my SB2, and I have no issues when shooting it on any of the three frames. I did that just to see if I would have problems, and then put it back on my SB2 frame and leave it there.

Useful information! Thanks! :)

223 is not advisable on a SB1 frame

Funny, I bought a H&R in .410 about 15 years ago. I sent it in and had a .44 mag barrel fit last month. Just got my Williams peep sight in the mail tonight.

I went to their website to get the contact number. The site explained what barrel will work on what frame. Took about 4 weeks to get the gun back

[troyboy]

As stated. Low intensity cartridges would be fine.

Generally, it's not a good idea - AFAIK, the actions used to assemble shotguns are unhardened cast iron, and not forged steel.

Most centerfire rifle cartridges operating pressures are in the 50,000 to 70,000 for CF rifles (psi) or 30,000 to 40,000 (psi) for handgun chambers - instead of a .410 shotgun's 12,500-13,500 PSI range (larger shotgun gauges operate at even lower pressures).

The operating pressure for the .223 Rem is a little over 55,000 psi.
(a large caliber straight case cartridge will operate at a much lower pressure than a bottleneck cartridge)

Let's see.... .223 high pressure round on a .410 low pressure breechblock = hand grenade.
