Title: RB size for my 12 gauge ?????
Post by: Skychief on April 29, 2010, 08:57:56 PM: I have a T/C New Englander with a 12 gauge cylinder bore barrel.

Anybody know what size RB these like with a ~.015 patch?

Looking at the prices of these big RB's makes me wish I could find a few samples of balls that should be close. Any ideas?

If you have a New Englander, all the better...let me know what works in yours please!

Thanks, Skychief.

Great medicine for whatever is downrange!

Post by: Skychief on June 20, 2010, 11:39:24 AM: Update....I bought some .715's and .010 precut patches at Friendship. Shot these over 70 grains Goex 2f yesterday. They loaded great (nice and snug) and my results were very encouraging. They shot minute of deer ribcage out to 50 yards (which was the farthest I tried).

I am loking forward to tweaking my load and such. The POI was a couple inches lower than my POA at 25 yards. This of course was with the single brass bead and no rear sight. I may have to simply make the bead prouder, or, maybe a little more powder charge will bring POI to POA.

Thought I would give a quick report. Skychief.

I was impressed with its initial accuracy BigSmoke. Kinda wondering how well it might do with a little load development. I will get around to trying the load you mentioned above (thanks!).

I can't wait to see what it will do to a big bodied cornfed Indiana whitetail this year! That big ball has a lotta "oomph", no matter how fast (or slow) she's going.

Looks like I may be hunting for a .715 mould soon. It was a lot of fun with the big boomer, I have to admit.

Taylor Knock Out Value is determined by multiplying the diameter x weight x speed and dividing that by 7000.
A .54 rifle at 1,800 fps develops a TKO of 30.66
(.530x225x1800) / 7000

A .715 at 555 grains at only 900 fps = 51.02

Them big round balls really thump when they hit.
