My friend gave me a 308 savage axis as a wedding present and I already had a model 10 308. I had planned on cambering it in 25-45 sharps but didn't want to wait 8-12 weeks for a custom barrel. Then I found some McGowen 277wlv barrels in stock at mad dog weapons system. I had read about the 277 wolverine before and it has very impressive ballistics from a 223 size case. The bore size to case burn rate is very efficient giving even more fps and energy from the same weight bullets than the 300 blackout or 223. It shoots a 270/6.8mm bullet and nips at the heels of factory 6.8spc ammunition from a much smaller case.

The proprietor of this round has already made all the connections in the industry to have reloading dies made by LEE and Hornady. Resized brass and factory loaded ammunition from 3 other companies,case trimming length gauges, chamber gauges,reamers,head space gauges or anything else you could need for this round.

Resizing 223 brass is simple and cheap compared to 6.8spc ammo yet uses the same .223 bolt face and mags. It is also very efficient in shorter barrels.
