What standard of accuracy for rifled chokes?
I am having shotgun barrels altered to accept removable choke inserts. There are many manufacturers of rifled inserts. Since I can have Stan Baker alter my barrels for any maker's inserts,
1. What kind of accuracy should I expect to 100 yards from these rifled chokes using factory ammunition.
2. Among the many rifled choke inserts, which are the most accurate? Whose rifling is deepest?
3. If ammunition type is important, please identify ammunition that allows a rifled choke to be accurate. If you could briefly explain why this is so, that would be helpful.
4. I have 12-, 16-, and 20-gauge shotguns that I want altered. Considering only accuracy, is there a significant difference among the three bore sizes when using factory ammunition with rifled chokes?
5. If I want to try making my own "slug" ammunition reloads, what factors in bullet/projectile selection are important? I wonder about how the rate of twist such a short rifled tube works [together] with a bullet's shape?

My experience is limited to the Rem. rifled factory choke tube, but I'[ve found that one to be very good. Mine will hold a 3-4" group at 100 yards with Winchester plain lead forster 1 oz. 2 3/4" loads.

Seems to me Shooting Times or American Rifleman ran an extensive test on this subject two or three years ago. The Rem choke equalled a lot of the full rifled tubes. I know you can find 12 ga. and I think remington and maybe browning make 20 ga. rifled chokes. I highly doubt the 16 ga. is made.
The best loads for rifled tubes/chokes are the saboted loads. Every gun likes one or two loads better than the next so is difficult to say. I have used Winchester for a number of years tho the new Remington is supposed to be good too. They will not probably shoot to the same point of aim.0 -
i have a rem 870 with rifled choke and it shoots about 3 inches at 80 yards, not bad for a $300 outfit 0
