Appears I did learn about a clean bore recently with my shotgun. You may recall I was having serious accuracy problems with my Remington 1100 shotgun. It was shooting slugs about 6 inches low and shot about 4 inches low--at 25 feet!
Bought some Shooter's Choice solvent and scrubbed the devil out of the bore of this 20 ga. Sales person at Gander Mountain recommened Shooter's Choice over a Remington solvent--both supposed to remove the plastic residue left in bore from plastic wads. In the past all I've ever used is Hoppe's No.9 solvent. Is Shooter's Choice a favorite with some of you guys?
After using Shooter's Choice both slugs and shot did much better. I wonder how much better the slugs would do if I'd replace screw-in modified choke tube with IC or cylinder tube? I know a more open bore is supposed to be better with slugs. Where's a good source for these screw-in choke tubes? Is cylinder even better than improved cylinder when shooting slugs? Which is best for buckshot?
I recently shot various slugs and shot for accuracy and find my gun's accuracy varies considerably with brand and load. Glad I didn't try to bend my barrel when all it will probably take is the right load with the right choke--and a clean barrel!
With respect to rifles, how much difference does a clean bore make for accuracy? How bad can copper fouling effect accuracy? Copper fouling is something I've never addressed until recently. I've never done enough shooting and comparison with clean and dirty bores to know.
I've had lots of guns (mainly rifles) over many years and should really already know the answers to the above. Never too late to learn.
