The company lists them as their .43cal balls, but they actually mic .41-ish.
The listed retail price is $30/500, but I was able to work a bulk order purchase discount of 30% with Charles and ordered several thousand for a group of guys for $20/500.
NOTE:
Although you can't see it with the naked eye, there is some minor manufacturing tolerance variations in these inexpensive marbles.
You should sort them a few thousandths smaller than you would with lead balls for this reason: occasionally one will be slightly out of round.
If you unknowingly mic it across is smaller diameter and think its OK, but then it unknowingly gets short-started into the muzzle across it's larger diameter, it could wedge in the bore. A ball puller is no good on solid glass of course, and you can't dare try to shoot it out as it would be a bore obstruction midway up the bore.
I learned this the hard way the first time I went to the range...had a devil of a time with a large mallet and solid brass rod driving it the rest of the way down...(it shot out fine).
So I sort using .568 as my max threshold and use .022" pillow ticking patches so I have leeway to accommodate that...have shot almost 600 since then and they all load like Hornady balls.
Everything .569 and above I set aside for the .62cal with .030" patches...outstanding accuracy...and I'm not even waiting for lead to get anymore expensive since these are so accurate and cheap just for plinking...shot another 50 at the range yesterday morning...total projectile cost to punch 50 holes in paper targets at 25 yards was .50 cents.
For best precision accuracy you have to drive these light 65grn marbles with a good head of steam and I get almost single hole accuracy with 80grns Goex 3F. But for general plinking just to enjoy shooting and practice shooting form, 40-50grns powder is also fine, but the groups will run a little larger at 3-4".
(the light 15grn rubber balls also do best with high velocity)
