I am using Ramshot Hunter powder, and was having a tough time getting groups worthy of a bolt action. Shaunpisk suggested I use a magnum primer; and luckily the grocery store had 10 packs of magnum primers left, I bought 3.
I have a can of H380 that never worked with anything, it is also spherical powder; so I have a 5 shot ladder with it, using the magnum primers.
My videos are not made for kids.
