Rikky Lee, thank you for the kind words. I spent alot of time reading and researching because when I decided to try this I was new at both reloading and with wildcat calibers. I was very familiar with the AR platform and had built several but had never done anything with an odd caliber. This site turned out to be a wealth of info and contributed heavily to my parts selection. Thanks everybody!
I understand what you are saying about 25 yard groups. I have only shot at close range because my long range is a muddy cornfield. I'm hoping to shoot at 100 yards (with the suppressor) very soon.
I was leary of going heavier than 110gr for supersonics because I didn't want to lose velocity. Since I'm at 2100 fps now and a heavier bullet would obviously be slower I figured 110's were the way to go.
As for hunting, the only things I can legally hunt in IN with a 300 are squirrels and rabbits. Deer are shotgun or pistol caliber rifles only (minimum bullet diameter of .357 along with cartridge length restrictions) so no go there.
Since I'm a Police Officer I tend to think of critters of the 2 legged variety when it comes to terminal ballistics and if the 110 is Hornady's recommended TAP round I figured it couldn't be a bad choice provided it will expand at sub 2000 fps. I intend to check directly with Hornady about that. That said, if the Nosler and the Barnes perform well at their respective velocities there is no reason not to give them a try. I will keep them in mind.
