.12 caliber to .17 should do the trick
Depends on the ammunition. Rifled 12 gauge slugs are accurate to about 150 yards
If the cylinder is in fact chambered for .22LR, and is fitted and timed correctly, then .22LR ammunition would be correct to use. Using .22LR ammunition in a .22 Magnum chamber will cause the case to split. If in doubt, have it checked by a gunsmith. sales@countrygunsmith.net
Completely depends on the ammunition you use. The long barrel tends to be just a little slower with most .22 ammunition but they are a highly accurate rifle with most ammo....
Answer, yes it can but DO NOT DO IT! lcj
7.62x39 ammunition. Be sure to check the barrel for caliber. Some weapons called "AK" Are chambered for different calibers. .223/ 5.56.....5.45X39 ETC.
The Marlin model 1894, chambered in .44mag, will accept all factory .44 magnum ammunition. I recommend jacketed or semi-jacketed ammo to prevent lead from fouling the barrel. Other than that, you're good with any "off the shelf" .44 magnum ammunition you choose.
You want a 1 in 12" or 1 in 11" twist. The twist is not only important for accuracy and stabilization of the bullet, a faster twist decreases velocity and increases pressures (which is bad). You also want a barrel that is chambered SAAMI "Spec II" or in other words has chambered with a .100" freebore or throat. The freebore is required to have a reliable, accurate rifle that functions at safe chamber pressures and allows safe use of most commercially available ammunition. There are a lot of manufacturers still selling "Spec I" 1/9 or 1/10 twist barrels, be careful.
The 19th century muzzle loader was quite inaccurate. This is because there is no rifling in the barrel. Rifling is the grooves in the barrel that cause the ammunition to corkscrew and the bullet fires straight and true(er).
I'm assuming you have a Marlin model 1889, not 1887, as they never made a model 1887. The 1889 does have a patent date of 1887 on the barrel, so this is a common mistake. Any Marlin marked ".32W" on the barrel will normally be chambered for the .32-20 Win. cartridge.
Reduces barrel fouling
Yes as long as you get one made for the Winchester model 1300 and chambered for the same length of shotgun shell that the receiver is chambered for.
Well, no.... not if the receiver is chambered for 30-06.
