.177 sub 12fp slugs / barrel combinations

Have you tried the Mako slugs? Some have good success with them, but they need to be hand loaded to ensure they enter the barrel straight. Many lightweight slugs suffer from the same problem in that they have a very short length in contact with the barrel and can be slightly crooked when pushed into the barrel, especially from a magazine.
Slug size relative to your barrel diameter is also critical, you may need to slug your barrel to find out its exact diameter. The slug diameter should ideally be around .001-.002 larger than the diameter between the lands according to US forums.

I had the Hatsan AT44 on Zan's in a shootout against my
FTP900 and HFT 500 at FT distance.
The comp guns did a little fingernail group at 55yds, the Hatsan did a thumbnail and from the impact noise, hit a whole lot harder.
II was very surprised how well the BSA R10 shot them.

yes, tried the Mako's too... not bad, but not as good as lead diabolos
I apprecaite the criticality of barrel size matching, hence starting this thread.. I can machine a barrel from something to fit one of my rifles.. just need to find a likely donor

Ive tried five different barrels, choked and unchoked along with a big selection of slugs shot at various fps too but never found one that delivered anything near useable accuracy

A mate has just tried a few light jsb .177 slugs through his r10 with a chokeless Cometa barrel and says its worth investigating, so he has ordered a box of samples and will test soon

My Phoenix MK2 with BSA barrel shoots Piledriver slugs very well, but they're way too heavy to be any practical use. It was designed to shoot them, the loading probe locates in the base of the slug to load it straight.
