Attached File Not gonna lie, I’m pretty excited for this. 338 ARC 7.5” bolt action upper which will be SBR’d soon. I’ll be adding a stock, and I want to swap the rail too—maybe one of @green0 ‘s suppressor rails for a tucked look? I’ll probably add a QD bipod as well, and I’ll definitely paint it. No ammo yet but really interested to see how long I can stretch it out, 3-400 maybe? |

I’ve already got a .300blk rifle and I only plan to shoot subs through this, so I figured the bolt action was the way to go. Plus it keeps me from burning through expensive ammo fast

It’s really disheartening to put together a new gun only to find out it doesn’t feed, has terrible accuracy, or has some other flaw that’s tough to correct. Good luck with it OP. I hope you can report success soon. |

I hope you can report success soon. I hand loaded some 285gr BTHP subs at 2.25” OAL which fed pretty well. I plan to swap rails at some point, and when I do I’ll try to polish/blend the feed ramps and see if that prevents the blunt tips from getting hung up. |
