What size round ball are yall using in your kibler 20 ga Fowler?

[Texcl2]

I just picked up another kibler fowler kit, this time a walnut 20 ga quick ship. I’m gonna be buying a round ball mould for it, what size are yall using? Have any of yall measured your bore diameter?

How tight is that ball/patch combo?

My smoothbore isn't a Kibler but is a .62 (20 ga). I shoot a .600" lead ball from a Lee mold with a .010" to .012" flannel patch. I also have a Tanner .590" mold.

Don’t buy a mold yet
If you shoot bare ball you may get best with .610
A patch .595-.600
Paper military style cartridge a .575
Play a bit and see

When I was shooting Larry Zornes barrels , true 20/guage , I shot .595 ball for patched loads and .600 for bare ball loads ... My barrels now , although called 20 ga. are really 19 gauge since the I.D. is .625 .... .600 is great for patched ball .... Order ya a bag of .600 and a bag of .595 and try them out , see what ya think of em before ya buy a mold ....

I might pick up a .595 mold with my next track order since the mold isn’t much more than a bag of round balls. I’m considering getting a very basic rear sight and dovetailing it in, I’ll have to figure out how much barrel thickness is there to work with. Have any of yall installed one on your kibler fowler?

What distance was that from? I'm putting together a 16 gauge Kibler and wasn't planning on shooting round balls... but now you've got me thinking.

Only 25 yds, had to bend the barrel to shoot POA. Working pretty well now.

Only 25 yds,

It's still a good group.

I have a couple of boxes of .570 hornady rbs that I have been shooting in my kibler 20g Fowler. I use two .017 patches and I am getting 6” groups at 55yds. Come this spring, I will cast some .600 rbs outside when it gets warmer.

I couldn’t get mine to group with .600 balls.
I had .575 on hand and with a .020 patch they shoot great

Good advice.

Not on a Kibler, but on my Centermark TFc and on my Lancaster style smooth rifle, when I built a track of the wolf NWG I added a rear sight to that

You did not say how far away the target was.
Pretty important information.
