Just read up on the round after your post, It looks like what the 300BO should have been. I was never enamored with the BO, but the ballistics, accuracy and terminal effects on the HAM'r look pretty impressive.Man I tried hitting post right when the Update hit last night, it all looks a little fancier now..
Anyways, I was finally able to catch one of my boolits in some gallon jugs (took 12gals to get 1). It was traveling roughly 2,200fps @ 30ft into 2 of the taller Gallon jugs laid on their side. It was stuck in the plastic on the back halfway through.
Nice mushroom down to the Aluminum gas check

This is probably the best group 2.25" 8 of 10 @50yd, 10 shots from a little wobbly tripod after too much caffeine.. Excuses But I'm very pleased at these results for the second outting with my very own design. Not one single failure to chamber or feed due to super short COL, Nose Design, or Ogive Tangent.

Avg. 2,335fps for 1,610ft lbs. would most definitely put a hurting on a Four or Two legged critter.
I'm ultimately hoping to dial it into a 3" 100yd load and use it for insanely cheap plinking or even hunting as the top bullets for 300 HAM'R are non-existent for who knows how long.. I literally have 5-10k Jacketed and All Copper .308 pills I've rounded up that are just not suited for the HAM'R.. Some pretty darn good ones that will most likely be sold off to fund some lead, hi-tek supercoat, and maybe a new firearm. Happy & Safe Reloading to Y`all!
Did you realize though, for a few reasons it's a Super-Sonic ONLY Cartridge. The barrel twist rates are 1:13" & 1:15", the latter being on it's way out (Bill Wilson said on THF that they only have a few 18" 1:15" left and then they're done with em` until the panic rush is over).Just read up on the round after your post, It looks like what the 300BO should have been.
