Shooting slugs without a slug liner?

generally "SLUGS" do best in straight wall bores having NO CHOKE.

Some slugs will have contact bands where the rifling hangs on to spin it and not be in full bore contact as a powder burner bullet is. ( It is a DRAG thing )

Solid side slugs when literally forced threw a choke absorbs a lot of the slugs speed and energy as the choke actually crushes the entire contact area to bore smaller and will exit slower than a straight wall non choked barrel would exit.



Pending caliber, style of bullet / slug etc ... have varied results in choked barrels. Loose chokes do better than tight and some folk have great luck in choked barrels. hard core bullet shooters however almost exclusively use straight bore chokeless barrels.



Twist rate also gets changed from pellets and slugs when longer distance come into play.

Wow, there is more to it than I thought! Thanks for explaining.

If it was really windy it would. 

I was shooting with a 15 mph nearly direct crosswind today and at 50 yds there was only about one-half inch of wind drift. That was with 23gr NSA slugs at 925fps.

Had I been shooting 18gr pellets at that same speed, I'd be looking at about 2" of wind drift. I did shoot those pellets today through the slug liner at 980fps....wind drift was about 1" at 50yds.
