BMiracle, I have an NEF .223 with the standard contour barrel and wooden stock. It shoots pretty good. Without any specially prepped handloads, I was getting 1 1/2" groups at 100 yds. Now that's not "gee wizz" accuracy but it's not bad for a break action $225 rifle with ordinary reloads. Once I get enough cases that have been fireformed in this rifle, I'm going to do some serious accuracy reloading. I'm going to seat the bullets out closer to the rifling in neck sized cases. Since these guns have a 1:12" twist, best accuracy will be with bullets of 55gr. or lighter. I'm concentrating my efforts on the 52 and 53 gr. Sierra Match Kings.
Sub-MOA groups are not only possible, but likley.
If you haven't already, you need to send your rifle to NEF and have a shotgun barrel fit to it!
These NEF Handy Rifles are some of the best kept secrets out there! And once you get a switch barrel, you won't be able to stop until you have them all!
