rifled choke tubes for sabot slugs and cylinder or improved cylinder choke tube for foster type slugs. you can shoot slugs with semi-auto. experiment to find what cycles the best without jamming.
Should have choke tubes, being that you can change it to whatever choke you want, so there would be no marking on the gun. There would be markings on the end of the choke tube though, usually between 1-5 lines. Not positive on which means what, but I believe the higher the number the tighter the pattern. But take that with a grain of salt.
The semi-automatic pistol cartridge, the 10mm Auto, developed by Jeff Cooper was first designed in 1983. This cartridge was used for various purposes which include hunting, defending and tactical usage.
The semi-auto and full auto AK-47s have different designs. Not only does the full auto have different parts, but those parts cannot fit in the semi-auto only version of the AK-47. It is against US law to have a semi-auto that can be "readily converted" to full auto.
The M14 was never factory made as a semi-auto.
Yes, You can change the barrel. I would suggest sending it to Briley or another reputable choke tube manufacturer to have it changed to the briley or win choke removable choke tube. You can also purchase a rifle sight, slug barrle for under $250.00 from most retailors
Absolutely. A Semi-auto marker will still benefit from an electronic hopper, just not as much as an automatic one. However, it is possible to outshoot your hopper, so an electric may be a good buy if you have speedy fingers. They also have the added bonus of not jamming.
The SKB M-7900 is a pump shotgun not a semi-auto.
More information is needed to identify what you have to be sure; However, it sounds like you have an Auto-5 Shotgun made in 1929. Auto-5's are semi-automatics. 81140 is a serial number, not the model. By variable choke, it's probably a poly choke device which hurts the value. While there are too many unanswered questions to determine value. Most Auto 5's from the 1920s with a poly choke in average condition usually fall between $250 and $400.
There are currently no semi auto firearms on the market which chamber the .45 Long Colt.
Semi-auto requires the hammer to be cocked for the first shot.
