Eley has already segmented the solutions and identified application-appropriate “models”. Frankly, getting down to lot number is the key and testing at that level is where the rubber meets the road.

Suggestions:

1. Go with the “model” that matches your application.
2. Buy 2 boxes (not bricks) of all lots that have enough stock to reasonably expect that, once you have identified the lot that works best, there will be enough boxes in stock to get a brick or more.
3. Be VERY, VERY prompt in sample lot ordering and testing. Place you real order ASAP after testing – on your cell while still at the range! Seriously!

FYI, Killough is getting stock all the time, and selling it all the time, so checking their site daily is worth your while. They ship quite promptly, so they are doing their part.

Good testing and shooting!
