Bullet selection is key to good accuracy. Select a Good Match bullet and do a load work up with different powders. Work your way up looking for that magic powder/bullet /charge combo.

Here is a little work-up I did a few months ago with a new to me Midsouth 55gr Varmint Nightmare. Stock Colt AR-15, 100 yards, 10 rounds each target.
Notice the accuracy node from 25.5gr to 26gr.

Varget likes to be compressed. You might need to up the load. I am running 25.8 grains in mil spec cases with 55 grain hornady fmjbt seated to the canalure with no signs of excessive pressure. Max is 27.5 grains in commercial cases which are thinner according to the Lee book. Do not use my loads. Work up your own. I know accuracy improved with the heavier loads which I ran in .2 grain increments starting at 25 grains.

Stock Colt 16" HBAR Carbine.

Crimp is with the Lee Factory Crimp Die. Medium Light Crimp.

You need to mind your barrel twist also. 55 grain bullets are fine for 1:9 twist but if you have 1:7 twist, your heavier bullets will be much more accurate. Try some 77 or even 90 grainers for 1:7 which I believe is what the Colt LE has.

Absolutely. Gun rag writers cause an awful lot of totally unrealistic expectations.
Even if these gun rag writers are shooting these great groups they have the gun locked in a vise. It's not like they are holding the gun and shooting it.

As with most handloaders, load development requires and good solid bench and a good solid rest. It may not be "Locked" in the rest but cradled securely for sure. It's the only way to test the loads and firearm.

My colt is an older Sp 223 marked on barrel I'm pretty sure it's a 1 to 12 it's like a 1974ish with a slick side . I don't believe it would handle the long stuff. Now I'm working a load with good promise with my 1 to 8 S&W with 77 noslerhp/bt with 24.3 of varget. I'm getting 1.20 MoA at the moment, but hope to improve that.
