CVA Double Rifle 50 cal.

[Chris Cade]

anyone out there with any tips on getting both barrels to shoot about the same? i tried some t/c maxi hunters and roundballs the other day. niether barrels would group close. i know i can try many different load/bullet combos but maxi hunters and rb are all i have at the moment. would hate to spend $100+ on several different boxes of bullets, but i may not have a choice.

For now I would strictly use the round balls to figure out a good load and get it sighted in, and only work on one barrel to start with. I don't know how well regulated (or at what range) those CVA double barrels are.I would get one barrel sighted well and then adjust hold for the other barrel.

 

Mechslasher,
CVA made 2 different double rifles. One had a band at the muzzle to help regulate the barrels and the other relied on the sight adjustment. It's a damned if you do and damned if you don't regulating process, getting both barrels to hit the same POI is going to be pretty tough. Sighting them in seperatly is the best you are going to be able to do. The ROT is most likely 1-48 which is more conducive to round ball than maxis. Mine is an older Express model and is still unfired. Anyone wanting to try one of these things out, contact me.

I don't know what your rear sight is like but you might consider the double-leaf type as used on the Kodiaks. CVA had a terrible time regulating their doubles. Seemed like every Shot Show was "this time, for sure!" They tried laser-alignment and then went to the adjustable front collar. I'm sure you can get them pretty close if you use that rear sight. Can't say I'm a fan of them but whatever works.

Just a thought, but wouldn't it be advantageous for one barrel to shoot a little higher than the other? If you miss the first one, the next is most likely going to be further away. Is the problem you're having with regulation windage, elevation, on both? You may try different loads in each barrel to compensate, if you haven't tried that already.

i'm planning on taking the rifle to my range and start with about 50gr. of ffg and work up to about 90gr. and see where the balls hit. i'm fairy certain both barrels will not "like" the same load. i also plan to use different thickness in patches with different loads to see what happens. it would be nice to get boths barrels inside a 3" circle at 50 yards using the same sight. something to look forward to doing when school is out for summer break!

I had one of those a number of years ago. Their best value is that the rifle will help develop your 4 letter word vocabulary. Mine would print a good group with one barrel, and the other barrel would print a decent group several inches low and left at 50 yards. I really liked the idea of a second shot, but not if that shot misses by a mile. I was tempted to mount front and rear sites for EACH barrel, but two stock welds didn't seem like a good idea either. I sold it to get a flinter, and haven't looked back.

Barrel "regulation" is a major problem with double rifles. It takes a lot of time and a great deal of expertise to get those two barrels to shoot to the same point-of-aim at a given distance.

This plus absolute reliability being the case, it is evident as to WHY fine English double rifles COST so darned much, n'est pas? :v

Ron is right. To regulate double rifles, one must solder and un-solder the barrels until they have the same point of impact....and that is usually at 50 yards with a VERY SPECIFIC load. Change one component of the load and you are back at having 2 separate points of impact. cheers Paul

 

[Chris Cade]

what about filing the crown of the barrel to move the point of impact of the second barrel? how would i go about doing to this to move poi?

I have a .50 cal. Kodiak double rifle that gave me the same problems. I was told that the double leaf rear sight was intended to sight the barrels for two diffferent distances. After much fiddling and failing to get the two barrels to shoot to the same POI, I decided to use one rear sight for one barrel and the other for the other barrel. Two barrels, two rear sights...It worked but with only one front sight, it was on target at only one distance. If you were shooting at a distance different from the one at which I had sighted in the barrrel, the windage would be off. Within the range of the gun, the amount that it is off is admittedly small but it is off and that is a pain for me. It works pretty well for me and it is an interesting gun but I think I will sell it and get another smoothbore flintlock
