Shilen 243 1 8 twist barrel issues

Описание: So we are starting this video as a reference to you the consumer as what can be expected when you have a barrel that will not group.I started this journey with a midway usa bought Shilen 1-8 twist 243 26" varmint profile barrel. Broke it in properly the way that numerous barrel manufacturers explain on how they want you to do it.

Build sheet
Choate ultimate varmint stock glass bedded to the action
shilen 1-8 twist 26" heavy varmint contour chambered in 243 win
egw 20 moa down tilt scope base
burris XTR II 5-25 SCR-MIL scope in nightforce 34mm rings
Berger 105 VLD Match Hunters, and 95gr sierra matchkings
Remington brass switched to norma brass after break in

So after barrel break in i started working up loads to find a sweet spot to load in i found that H4350 with 105gr seated to .40 jump to the lands gave me the best accuracy to SD which was still around an inch group. I tryed the powders as follows H1000,IMR7828,H4350,IMR4350,H4831 and varget and we didnt just test one load of each we tested every charge for each powder from middle of the road charge up to max 5 shot groups each.

Nothing gave us an except-able group at all best we could get with 105Gr was .790 little over 3/4 of an inch.
with 95gr smk it was a bit better with a 5/8 group but still nothing to write on to mom about.

i totally tore the thing apart and reassembled it paying attention to every detail tourqe barrel 45 ftlbs action screws 35inch lbs front 30 rear tightening the front one firs. this still resulted in no change.

called shilen and hey wanted the barrel to inspect so that where we are barrel sent into shilen and waiting on a reply will update when i get it back.
