this is slightly related but I can't speak to accuracy yet.
My FG just arrived today and I ran various factory ammo thru it to test feeding. Win 240, Speer GD 210, Rem 210, Fed Cast Core 250, Corbon 250, and Corbon 265 fed just fine on a limited test basis. My big surprise were the Corbon 265s. I sure hope they really work as that load really ups the performance in my mind. Will have to test them with a full magazine and while firing. Even some of my home loads with 265 Cast Performance LFN fed ok as long as the gun was level. I bought the gun expecting the 265 LFN wouldn't feed at all. Now I just hope they like the micro groove rifling.
Maybe I'll learn on Friday when our range is open.
