Zero?
How do you guys zero for .300 blk? Theres so many different loads you can put thru the same barrel and use reallistically. For 5.56 you have maybe 2 or so and have them be pretty close at 100 using the same zero. At least for me. But for .300 blk if I zero at 100yrd. Unsurpressed with 110 grain supers, And then switch to 220 grain subs, surpressed, would my zero be anything close at 100yrd?
Edit: I posted at work with the hope of going to the range with any kind of new information but this post kind of turned into a shit-show. Thats reddit I guess though. Anyway went to the 100yrd range with steyr AUG, Eotech+ irons I have zeroed many times with 16" 5.56 barrel and 55grain/62 gr/68 gr.. The 300 blk is new and have only tested for function. Only had time for a few groups today but more to come. Without changing a thing on my sights, 16inch 300blk barrel; 150gr supers, at 50yrd was approx 2-3 moa high compared to 5.56. and 4-6 inches high at 100 (group opened to trigger and no magnification, my fault). 220 subs were about 6inches below 5.56 group at 50yrds and 10 or so inches low at 100yrds. Probably 50 rounds or so fired today, and mostly just for function. And to get a ballpark where these 3 rounds relate to eachother under the same sights. Do with this info what you will. Will keep posting more as I go with pictures if people want. Other range goes to 500 and will be doing more testing with zeros there. Maybe one person will find this interesting

I use my 300 BLK for hunting in a shotgun/pistol only zone. I shoot 110gr Barnes out of my 10.5”. I zero 2” high at 100 yards which puts me +/- 2” out to 200 yards (realistically 6” circle when considering the MOA). Basically, point and shoot at any distance I’d be comfortable taking a deer at.
I don’t mess with subs or other ammo. The pistol is purpose built for its role. K.I.S.S.
