The 185 comes in a box of 250,the bait shop I get mine,he breaks them down in groups of 50 and sells them for $7.?? per 50. I was thinking they were .451 but just miked a couple and they were .452. Was told that these were made to expand better at muzzleloader vel better,by the fellows that were using them first but haven' t seen anything in writing.
If you are interested in them I can get the info off the box and post it for you.the next time I go to the bait shop
