I measured the barrel I've been burning all year with the LNL OAL Gauge and found I needed a mag length of 2.943 with that barrel just to reach the lands. Fortunately I just had an order from Apache Gun Works show up so I spun a fresh tube on the Mausingfield.

8 twist, 26" heavy Varmint contour, I'm running an APA lil ******* on it. I'll break it in at the match this Sunday. Quick zero, run the chrono, and play the game. Further load dev on labor day weekend.
