I have a 16X16X8x57jr drilling and would like to add an adapter of some small caliber for "potting" small game. Has anyone used MCA Sports adapter (made in Alaska)? The company markets adapters for rifles and shotguns. Which adapter (rifle or shotgun) is usually more accurate and easiest to "regulate?" Also, what cartidges would be the most useful in a drilling, whether it requires handloading or not? The calibers I am considering for the shotgun barrel are: .22LR, .22WRM, .38Spl, .45acp, or 45Colt. For the rifle barrel, a Lothar Walther insert in a .22LR would be my adapter of choice, which is available through "Akah". Thanks, Mags | ||

I have a couple of MCA adapters and they work OK, but I don't think that they are accurate enough to reliably harvest small game. There used to be an outfit in Bozeman, MT, that produced an auxillary cartridge for use in a rifle. You used a 22 LR cartridge to propel a hollow based soft lead bullet that was quiet and produced reasonable accuracy out to 50' or so. There is also a guy in Canada who will build you an auxillary rifle chamber that uses 22 blanks, the type used in construction, to propel a lead bullet made from buckshot, IIRC. Jeff | |||

I have about seven or eight different adapter cartridges, most of them are old marble or similar types. While I have tried innumerable times to make them work for small game, they are poor substitutes at best. Just got one for in my 222 to use 22 mag, but sold the gun before it got here. I would think they would be good enough in a rifle of similar bore diameter, but the ones I have shot through shotgun barrels have left a little to be desired, more of patterns than groups.

I wonder if a 32 H&R mag would work in your 8mm barrel? Is the J the .318"? | |||

I think you should get a barrel insert (einstecklauf) in .22 Win mag or hornet fitted to one of your shot gun barrels. The insert is fitted by a gunsmith and some models can be fitted ones and then set and remowed without tools or a shift in poi. A great device that usually delives moa precision at 50 yards or so.

260 - Thanks for the report on MCA. You and Black Fly answered my accuracy question. Lar45 - The 32 H&R isn't listed as an option for the 8X57jr (.318 bore); however, the .32 S&W Long is listed. I believe that cartridge is darn near obsolete. Husqvarna - The barrel insert for the shotgun to be fitted would work, Krieghoff makes one; however, I would prefer something short enough to carry in a small pack or shooting vest. Are you familiar with the Lothar Walther .22 adapter? Regards to all and many thanks for the info. Mags | |||

The 32 S&W long is .93" long, the 32 H&R mag is 1.08". That is the only difference. COTW says they both take a .312" bullet. You might see if they would just cut the S&W chamber a little deeper. Or just reload your own. Midway has 32 S&W long brass in stock. http://www.midwayusa.com/ebrowse.exe/browse?TabID=1&Cat...*652***670***9014*** | |||

Do you mean one of these? I have no personal experience with them however i still see the inherent inaccuracy of it. I do belive that you are facing one tough Q here, either get the precision desired with a longer rifled insert or to settle with less accuracy but a quicker system.

I bought MCA adaptors for my 223 - I tried both the 22LR, and 22WMRF versions. Fiddly things to use, and god help you if you drop the firing pin insert in grass!! The 22LR adaptor is currently rusting in the bottom a dam, which is where I threw it a couple of years ago. The 22WMRF is good for putting down injured or bogged stock, if you can get close enough to put the muzzle against the animal's head. Other than that, a total waste of time and money. ******************************** A gun is a tool. A moron is a moron.

Or you could reload cast bullets with a light powder charge and just keep them in a seperate pocket while hunting. I've used 10 grains WC820 with a 165gn Lazer Cast in my 30-06. It makes nice little groups at 25 yards and is very inexpensive. I sight with the bottom post of the recticle of my scope Where it changes from a thick line to a smaller line. I adjusted the velocity up until it shot to that point. I've taken several grouse and a bunny with those loads. My 8yo Son can sit down at the bench and shoot them without any problems(very light recoil and not loud). | |||

i saw the einstecklauf answer in a prewar sempert & krieghoff drilling under the trap buttplate was a very large storage area which had individual compartments for the insert bbl and 2 or 3 rifle shells and 2 or 3 22 hornet shells for the insert bbl. now why can't they offer something like that in these "modern times " ?? seems like the old ways were better and that the germans have really lost their ability to engineer and create . they just copy what the italians do.

My experience is identical to Rugeruser. Save your money. I bought some 22lr for my 9.3x74r and they were crudely made, impratical, and innaccurate... Before all else, be armed. Machiavelli | |||

I have several Kreighoff einstecklaufs for 12ga. They are a bit touchy to regulate at first, but they go right back to zero when taken out-put back. They are in 22 mag. I'm getting one soon for 16ga. They are expensive but work very well. They go into several of my drillings and are regulated to shoot POA with the scopes at 75 yards. | |||

pls be advised there is a difference between a chamber adapter and an insert barrel. the chamber adapter is just the size of the chamber. there is little if any rifling in it the adapters merly hold the subcaliber ammo. there is no way to adjust them. the insert barrel is typically 10" or more long. it does noquire a firing pin adapter. it can be adjusted to shoot to the sights. some can be removed and re-inserted with no change in the shooting. others have to stay in or be resighted when removed & reinstalled. check out website for mca sports/ace bullets they have both styles - adapters are about $30, insert barrels are about $65. 18" insert barrels are $101 TOMO577 DOUBLE RIFLE SHOOTERS SOCIETY | |||

MCA bought Harry Owens out many years ago and over the years i bought numerous adapters from Harry. I even had Harry make up some custom adapters on idea's i had. Really they are for "quite close range", if you want the best results. I've find the best of all by far are the Krieghoff 22lr or 22WRF inserts. They slide into a shot bbl., lock into place and are sighted to your sights. They ALWAYS come back to POA.. I find them to be just as accurate, or better than as a decent bolt action 22... I carry mine in my pack so i can slide it in as needed... OR, like was already said, make up some low powered rifle rounds for your rifle bbl... DM | |||

I tried a couple different types and never had decent accuracy with them. What I do is just (as some have suggested) load up some "cat sneeze" loads for the rifle barrel. I use 9mm makarov (@ .364) 90-100 gr FMJ bullets in my 9.3X72 and load them to @ 22 rf velocites. Very deadly on small game with no meat damage. You could make an upsetting die to make similar .318 bullets for your 8X57 JR or use a cast bullet cast hard & sized to that diameter.

Here's a pict. of one of my Krieghoff "insert bbls" in place..  They are VERY accurate and shoot as good as most 22 rifles...  DM | |||

I assume all the good ones (Krieghoff etc) are adjustable for POI?? Are the short ones (22 CM etc) as good as the long 44 CM inserts?

I think for my Valmet 412 I could use a steel model of a 9.3X 74 cartridge with a Makarov chamber inside it. Just to use the standard bore. I have the same idea in a .308 case that chambers a 32 acp. Good for rabbits and squirrels at close range! Low noise and recoil nonexistant. Packy | |||

www.einstecklauf.de www.waffenjung.de Here you can buy insert barrels, and Heym too. An insert barrel (Einstecklauf) is a very useful thing, but if you want to have highest quality a very expensive toy. Most hunters buy an insert barrel when they order their new combos direktly by Kriefhoff, Heym, Blaser etc. that guaranties you the perfect function. If you buy it later, a good gunsmith should do it first and testing the accuracy and training you in changing the barrel in a perfect way. This should be the right way. Burkhard | |||

You seem to have some experience with these Burkhard. Are the short ones (22cm etc) by krieghoff & (the other good ones), adjustable for point of impact? "You can lead a horticulture, ... but you can't make 'er think" Florida Gardener | |||

Greg, I never used a short one, and I dont know a hunter who does. Sorry. Burkhard | |||

I've had several short and long ones from Krieghoff, they both ajust for POI the same. The only difference in them is the length of the bbl... DM | |||

i am looking for a short insert barrel in 22 hornet. like the ones sempert & krieghoff used to make. has anyone seen one in 22 hornet ?? tomo ftondrus@hotmail.com TOMO577 DOUBLE RIFLE SHOOTERS SOCIETY | |||

I have borrowed a lothar 22magnum 12 gauge adaptor which is about 12" long of rifled barrel with sliding adjusters to regulate poi. Shot off 40 22wmr and still couldn't get better than 4" group at 40 yards looking down rib. I can't envisage any practical purpose for an inaccurate 22 bullet. | |||

trans-pond these inserts are made for use with sights. such as on a drilling or combo gun not looking down the rib, try shooting slugs without sights ! TOMO577 DOUBLE RIFLE SHOOTERS SOCIETY | |||
