Just as it sounds. I really only shoot paper and steel from 50-200 yards. Steel means I need to keep velocity below 3000fps at 50yards. Otherwise id go straight 20vartarg or 20practical.
Im also trying to minimize powder consumption. Barrel heat/wear/recoil etc... honestly... a 17hmr would work, but i want to reload it.
I started thinking a .17 but noticed bullet selection is limited. Lots of options 20 cal pills.
I have been kicking around a 6ppc build, and noticed .204 is %83 of 6mm... And the .378 case diameter is %86 of the .440... So lets make a %85 ppc!
And you get a 20VT but ~.159" shorter... Sooo could I take a 20vt barrel and shorten it? Or run a reamer shallow? Or am i stuck ordering a reamer?
I could start with a normal 20VT build with heavy pills and lighter loads, but ive read/heard that under filling cases tends to be inconsistent/other issues. Could i run a full fill of a slower powder? To get velocity down to 3000-3200 fps? But this would be less efficient in terms of powder use...
Ill admit i ran across another form member showing some short 20VT brass (.100 and .150") when google searching... but I never saw a build, or load data etc... as to if it actually worked....
If this goes anywhere it would likely be on a howa mini action or a rem700 clone like a solus.
Thanks!
