Yes but it shoots them terrible. I have one myself and I bought the Remington rifled choke tube and it helped dramatically. All Remington chokes fit the Charles Daly shotguns for your future reference. I also found that it shot the Remington Buck Hammer slugs the best.
Can you shoot a standard slug threw a modified and or improved?
no
As long as the maker doesn't caution against it. Have it checked out by a gunsmith
Is it a screw in choke?
As long as the owner's manual doesn't prohibit it.
no slugs should on be shot thru a improved cylinder shotgun. if you shoot thru any other choke it can cause the barrel to split
yes.
flowers are not modified leaf however we can say that in some of the cases petals of flower are modified leaves . In actual way shoot part of plant are modified into flower for plant sexual reproduction
Yes, it is, but make sure you shoot foster style slugs. They are easier to force (swage) through the choke, and are designed for smoothbore shotguns. I like the Remington managed recoil slugs. A 1 oz. slug coming out at around 1250 fps is nothing to sneeze at, and they're very comfortable to shoot. If bears are your concern, however, I might go with something with a higher velocity.
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
from around 8 (starter mechanical) to 32 bps (advanced speedball marker). heavily modified guns can shoot near 50.
Yes, but you will get better results with improved or cylinder bore.
