Well, now I'm completely and utterly confused. First, I have found all Remington, even the inexpensive Remington "Yellow Box" 55 gr FMJ to shoot no worse then any other factory 55 gr FMJ, and better then some.
I guess that this just reinforces the fact that all ammo is NOT equal in even the same weapon. We also have to remember that all Handis are NOT equal, and some are going to shoot better then others. And that all shooters are NOT equal, and some are going to shoot better then others. One of my Handis in 223, which was properly broke in, and has been tryed with at least 24 different factory and handloads, from 40 to 62 grainers, is an inch rifle. I've accepted that, and can enjoy it for what it is. If I need any "tacks" driven, obviously I need to reach for a different rifle.
Have you tried having another shooter sit behind your buttstock for a few rounds? Maybe a friend or even your old and feeble Dad? If he is willing to do your running to buy ammo, he might be willing to pull the trigger a few times for you.
You bougth it to be a "tack driver"? If you are willing to invest $1000 to $1400 in a rifle and scope, then you might expect "out of box" tack driving. With the Handis, sometimes you have to work for it. Sometimes it just isn't going to be a "tack driver".
Chill. Take a deep breath. Search this forum for suggestions. I think the fix for your issue is listed somewhere on this forum. (And that might be to accept it as it is or replace it.) And I'm sure more advice will be coming.
