[Raudy707]

Update: Build complete. 20" X-caliber carbon, Defiance Classic. MDT HNT-26, LHT 3-15x42. Weight with loaded mag is 8.25 lbs.

I've done some initial break in shooting with just some "off the shelf" hand loads using 168 Nosler HPBT and 4831sc. It's shooting 1/2 MOA even without proper workups. Pretty stoked to say the least. I forgot pull out the chrono so I don't have velocity data yet, but I soon will be shooting it side by side with my 2 other 280 AIs which were finished out in the 23-24" range.

That's a sweet set up!! With the 4831 it's going to be pretty slow. But it will be accurate. I tried to stick with H4831 and then finally gave in the pixie dust Rldr 23. Picked up 170 fps and didn't sacrifice any accuracy. If you have any, give it a try with the 168's. Can't wait to see your chrono numbers with that short barrel. Really interesting project
