Vannooch,

There is another option if you happen to hunt with a contender in a big bore. You used to be able to buy chamber adapters in various calibers that would insert in a Contender barrel, and make a single shot 22lr or other small caliber out of your boomer. These were fine for a single shot suitable for grouse or bunnies. But I agree, having fiddled with shot loads and capsules for a slew of guns over the years, the rifling pretty much destoys any hopes for any decent pattern at any reasonable range.

I did have one exception to this years ago. Of all guns, an AMT 45 ACP DAO backup would put cci 45 acp shot shells into a pretty tight group out to about 15 yards. I still have no clue why this gun would do this, but it was my one exception, having tried this in a bunch of guns over the years.
