Anneal before reloading after firing 2/15/2021
If you roll crimp these, it is a very good idea to anneal them before reloading a second time--and every time after that. They will stretch forward, so you may need to trim a bit once your roll gets brittle, but Ive gotten 5 blackpowder loads so far out of my test runs 65-70-80 grain charges. Without annealing, they will split.
150 year old 12 bore under lever double rifle still kicking 6/8/2020
Thanks to Ballistic Products and MagTech hulls my old double gun and I are still enjoying the great outdoors. I successfully harvested a large boar and a mature eight point buck with it last season. I am loading up and keeping the skills honed looking forward to next season. Thanks guys for great products and for keeping me and my old gun still kicking!
Great Hulls for BP 6/2/2020
Love these hulls! Easy to reload, consistent sizing, and clean up like any other brass case. They shuck out of a SxS very easy so a must have for Cowboy Action shooting.
Great, novel, permanent hulls 2/4/2020
I played with a box of these and converted them to smokeless powder capable. They look great and shoot great too. I use 10g plastic wads to compensate for the larger ID. Would be 5 if already prepped for 209 primers.
