Try it with H2 and H1 weight.
I’ve never used that kind of buffer. Do the weights slide like a conventional buffer?
Yes, Odin has sliding internal weights.
Tested H3-->carbine spring-->spingco blue--springco red and it got better but still wouldn't fire more than 4 rounds.
Tested 10 round ploymer mag-->30 round metal mag-->30 round pmag...same issues.
Tested 2 types of steel ammo to rule that out...same issues.
Was packing up and thought "try brass ammo ya nincompoop" and it started to work perfectly, so much so that I used brass ammo on every one of the previous configurations and I didn't have a single issue. I knew steel ammo isn't as reliable but I was kinda surprised how consistently I had the same problems and nothing would work with steel but switching over to brass allowed every setup to work perfectly.
Lesson learned...time to dust off the Dillon because this thing eats ammo.
