I have been in contact with http://www.mcace.com/ who offer a wide range of pistol and rifle caliber inserts. Their 10" rifled inserts ($95) begin as ES Shaw barrel blanks and are worked down to suitable gauge and length. I have ordered a 20 ga 30-30 10" adapter with a 1:10" twist which I think will work well with 150 gr loads. It's a little short and may take some handloading with a faster burning powder to get it right.

Provided it works out, I may also order a 12 ga 45 Colt adapter. A 10" 1 in 14 twist should give 75 yard accuracy in my mind and make for a great combo potential during deer/grouse overlap. An IC barrel with a 7/8 oz load for grouse and 250 gr 45 Colt in the Mod barrel.

Delivery is some 8 - 10 weeks. I will advise when possible.

Just ordered a second 20ga to .410 adapter to use in my SXS. Turning the ole twice barrel 20ga into a double .410/.45lc seems like a good idea in my mind.

I just got an IM from the member that bought a couple of extra .410 to .22 LR adapters that I had purchased from Short Lane. Here is what he wrote: "If anybody asks the adapters are perfect in a TC 45/410."
They should also work fine for those that have Handi barrels in .45LC/.410....<><....

Be careful about that. If the adapter is a true .410 shotshell adapter, it'll have a .410" bore. Not a good idea to shoot .452" bullets down a .410" bore. Maybe, though, it is bored for both.

Thanks for the heads up.

Not to worry, the adapter is labled as .410/.45lc so it should be ok. My only cocern would be if the old SXS would handle the .45lc pressure, but I think it should be ok with the cowboy loads.

Finally got the chance today to try out the 20 gauge to 22LR adapter from Gunadapters.com

I was lucky to hit the target at 10 to 12 yrds with the Topper Jr. I really wasn't expecting much considering there is no rifling,but it did go bang every time.

Oh well, live and learn.

On a side note, I've been shooting my 541T and was starting to get cocky. This adapter brought me back to reality. LOL

I was being sarcastic with my saying at least it went bang every time. I would like try the adapters that have rifling and see how they do.

MSP Ret · « **Reply #99 on:** April 01, 2012, 02:58:33 AM »

I still appreciate and will keep mine. They are not for long range, or even short range target work, but they work and would be highly appreciated in the correct instances with solid bullets.
With solid bullets they are good, with shot cartridges they are great....<><....

RPRNY · « **Reply #100 on:** April 06, 2012, 03:18:14 PM »

So, I received my 20 ga 30-30 insert today. Looks good, solid rifling, 5 external grooves for O-ring fitment. Here are some pics. May be a while before I can test it but I will report back as and when I have done so.

tranders · « **Reply #101 on:** April 07, 2012, 02:28:16 AM »

Looking forward to hearing how it shoots.

MSP Ret · « **Reply #102 on:** April 07, 2012, 02:39:10 AM »

RPRNY, that longer adaptor looks very nice. I would think any of the 30-30 loads in the TC Contender book which have been concocted to work with the shorter TC barrels should be just the ticket for it...Happy Easter....<><....

Drilling Man · « **Reply #103 on:** April 07, 2012, 04:27:55 AM »

The longer rifled adapters have been around just about forever. I bought this one back in the late 70's or so ?,

It does go bang, but i guess it all depends on what you are use to, i pretty much gave up on expecting to much from them many years ago.

Hello, where did you buy this one and how long did it take to get it. If you do not mine could you tell me the cost. Thanks Tom

RPRNY · « **Reply #105 on:** April 13, 2012, 03:15:08 PM »

Tom,

My 10" 30-30 rifled steel insert is from MCA sports and cost $ 101 including shipping. Turn around was about 3 weeks. I think the 10" in 9mm should gibe you real accuracy if you can work out POI vs POA.

Thanks I was lookng at 45-70 for a poor man's double rifle

Tom

RPRNY · « **Reply #107 on:** April 14, 2012, 01:44:29 PM »

I think the issue with the poor man's double rifle will be regulation. Shotgun regulation is not the the same as double rifle regulation and anybody that has struggled with the poor man's production double rifles from Baikal and Sabatti will attest to the problems with double rifle regulation. With one barrel, you can figure out POI and work from there. 45-70 inserts in a shotgun sxs could have widely different POI...

But, it's such a great idea and I sooooo wish it could work.

I tried it several times since the 70's, never got one to work out for regulation yet.

Well, I had a wholly unsuccessful mini-test of my 20 ga 30-30 insert over the weekend from Mace. I had five Hornady "Custom Light" 150 grain RN cartridges left in a box and fired them through my 20 ga Zabala Hemanos SxS at about 20 yards. The first round I held on paper dead center with the bead and hit roughly 3" right (out of the left barrel). I didn't notice the shape of the bullet hole. The next 4 shots "grouped" about 3 " - 4" slightly low and right of the x ring with the bead held at 9 o'clock on the x ring. When I walked up to the target, all four of the second group were key holed.

I couldn't tell if the first was key holed because one of the second group had kicked up some splinters that had marred the first hole. I removed the adapter and realized that the problem may have been caused by the insert losing its centering. It came with one O ring in the front most groove and centered well in the barrel. Unfortunately, the O ring covered a small gas port. So, presumably, the first shot burned through the O ring causing the remaining 4 shots to potentially glance off the shotgun barrel on the way out - one possible cause of the key holing. I will have to fix the O rings and try again.

gcrank1 · « **Reply #110 on:** May 01, 2012, 02:29:17 PM »

A small gas port in the barrel on a SxS?......say what?
I doubt that the bullet would hit the inside of a 20ga., even with the O-ring not entirely holing it centered , but you be the judge. You might try wrapping the front of the adapter with black plastic electricians tape for a snug fit.

RPRNY · « **Reply #111 on:** May 02, 2012, 03:31:33 AM »

My Mace adapter is a 10" long rifled barrel insert. Just short of the insert barrel crown is a small perfectly round hole which I have called a gas port for lack of a better term. It coincides with the last groove in the outer diameter of the barrel insert which are there for the O rings.

I am perfectly prepared to accept that there is no deflection off the SG barrel but since the rifling on the insert is deep, I am trying to account for the key-holing of the bullets. I would have thought the lighter 150 gr bullets would stabilize better in the 10" barrel than heavier ones. Perhaps I got that backwards?

gcrank1 · « **Reply #112 on:** May 02, 2012, 04:10:08 AM »

How well does a bullet fit the bore of the insert? Stick on into the muzzle and get an idea by where it stops on the ojive, or, better yet, run a soft lead sinker thru to check it out.
At 10" you might consider it more of a Contender for making reloads. As a confirmed cast bullet shooter, Id like to see if it would shoot cast lead, 100 thru the heavier; ie, 32-20 equiv. on up.

I still dont get that port.......maybe somebody can clarify that for me. If this showed promise, your best bet might be to have Mace get you one with the muzzle swell back a tad farther to clear it.

RPRNY · « **Reply #113 on:** May 02, 2012, 04:52:07 AM »

That's a Hornady 150 gr Spire Tip bullet. Seats nicely at the ogive in muzzle and at the lands. You can also clearly see the hole or port in the barrel at the final O ring groove - rendering that groove useless of course...

gcrank1 · « **Reply #114 on:** May 02, 2012, 06:06:08 AM »

Oh!, I misunderstood that the port is on the insert barrel.......

.
You certainly cant put an o-ring on that groove, will it fit on the next one back? I really dont like the idea of a port exiting hot gas into the barrel...........have you contacted him to see if it isnt supposed to be there?

MSP Ret · « **Reply #115 on:** May 02, 2012, 07:48:51 AM »

That hole in the barrel insert sure does not look as if it is supposed to be there. I have never seen or heard of anything similar before....<><....

RPRNY · « **Reply #116 on:** May 03, 2012, 04:51:35 AM »

So, indeed the port is not a port, it is a hole and not supposed to be there. I contacted Ace Dube at MCA and sent him a picture. He quickly responded to say that he would replace it. He said it was a new Remington M700 30-06 takeoff barrel that they had used and that the hole was the front sight screw. It should not have gone down to the barrel. Looks like another victim of post Cerberus quality control. I have to say I'm pleased with the immediate unequivocating response.

There is no way you turn (lathe machine) a barrel and not know there is a hole through it. You'd see the hole, and you'd look through it. Duh.

Question - in your first post you wrote "I have been in contact with http://www.mcace.com/ who offer a wide range of pistol and rifle caliber inserts. Their 10" rifled inserts ($95) begin as ES Shaw barrel blanks and are worked down to suitable gauge and length." So, Ace misled you? This turned out to be a Remington take-off barrel, and a defective one at that, not a Shaw blank.

Now I know Ace is capable of good work. I've owned a couple of examples.
But in this case I think all the blame is not due to Cerberus.

Well, be that as it may, he immediately said a replacement was being cut and sent. That may be just the right thing to do and it all may have well been his fault to start with. But in this day and age, someone doing the right thing without a kick in the backside to remind them is worthy of note.
