I tested some slugs in BSA. .22 barrel and in STX Superior liner.

The results are very different.

These are results of 19 grain .218" and 23 grain .217" at 24 yards from BSA barrel in my RAW HM1000X.

On the other hand the same slugs did very bad in STX Superior liner.

STX Superior liner shot well 27 grain .217" and 23 grain .218" slugs.

Both barrels behave very differently.

But with their preferred slugs as mentioned above both shoot 3/4" at 70 yards.

Looks like it's due to difference in twist rate and style of rifling.

Just a bit of sharing.
