Ok guys I have a question, and I apologize if this has been hit before. I just finished my first build. I have a standard receiver with a nylon bolt buffer, I have polished and radiused the bold and added a KIDD extractor, it has a Green Mountain 16.5" fluted bull barrel, and a Boyd's Tacticool stock. I have added a Blackhawk 9-13" bipod and an eBay scope. Now that you know the specs, my question has to do with ammo selection. I have read that many of the bull barrels are picky about ammo. This confuses me just a little. I mainly have this gun for fun plinking, and have a stock (read 4000 rounds) of federal bulk, that I used with the gun prior to the build (I have not shot it since finishing it this afternoon). How would I know it the gun is picky about its ammo?? Is this more of an accuracy thing or is it a failure to function thing when it comes to ammo?? Please help me because I don’t want to mess up this rifle with poor ammo selection. Also, if anyone has any suggestions as to other improvements that I can make to the rifle I welcome them (I plan on adding a match trigger set and extended bolt handle in the future). Could someone please let me know how to post pics????
