trying to collect sub caliber cartridges

[diesel04]

I am fairly new to the forum and have been a 17AH shooter for around 15 years and have been collecting standard cartridges for as many years, I would like to add sub-caliber cartridges from 10s, 12s, 14s, 17s, and 20s.

I currently have a 17Vr thanks to RoofMonkey and want to expand my collection.

Thanks

Mike
