So today I went to the range and put thirty rounds through the 10.5" and TROS can. I had Trailboss/55 grain projectiles @ 4.0gr , 3.5gr, and ended with 3.0 gr . All of the rounds went through. Point of aim and Point of impact were way off from the typical load used to sight in with (No big surprise there). But the range did have slight gusts of wind every now and then.
My questions are what load can I used where the gun will cycle? Why would the same load with the same POA have a different POI? |

I've seen these loads in my book and have bought the two powders that they talk about but have not loaded any yet.
Do the loads in the book fill the 5.56mm case? If not how much do they fill it? 2%, 50%, 80%? Been wondering about that. Thanks. -Arbiter Posted Via AR15.Com Mobile |
