The new downsized balls we have are coming in at .497 - .498 and is much improvement over the previous they were doing. They will work with the .505 CT's but are a bit to big for the .495 - we still have some .505 CT's from the very first batch but have run .495 on all loads after that.
If somebody does want the newer downsized balls make sure to let me know when you order, as we still have some of the standard sized balls as well and those are allot bigger. If you're confused as to what CT sizing you have let me know and I'll see if I can pinpoint it. Certain colors were exclusive to the .505 CT run while others were not.
The balls we have are the best quality on the market as well. I've seen the other .50 cal China made balls on the market and ours are of a much better quality, shell wise and material wise. The China balls are bigger than the new downsized American balls also and will not work in any of the CT's. Ordered some direct from the manufacturer to test.
