Well, put me in the Lee Factory crimp camp, although I
don't use small base dies, I do Full Length size my
brass. If I were competition shooting,
I would have to prove to myself that the Lee Factory Crimp
adversely effected accuracy. If it made a measurable
negative difference, I would not crimp. But for my peace
of mind, .223 Rem. ammo loaded for my ARs, is crimped,
and the accuracy is very good.
I have a .223 load, using a 55 gr. Nosler BT, driven by
Varget, less than one grain under published maximums,
primed with Remington small rifle BR primers,
seated to just fit in the magazine(2.25" OAL), that groups
sub MOA in both my M4 pre-ban, and my 20" Varminter.
The Varminter shoots some .2 and low .3 MOA groups,
and if memory serves, the average is just under .4 MOA.
I don't recommend the 55 gr. Nosler BT's for coyotes,
but for varmints, and paper, this is a very good load in
my rifles. My Tikka T-3 likes them as well. I am working
with VihtaVuori N133, for the Tikka right now, and when
I get the load dialed in, I am going to try a 2.25 OAL version
of this load, to see what the ARs think of N133 loads. But
I will be hard pressed to find a better load than the current
Varget load, in these two AR rifles.
