I would like to admit I am not a good shooter off the bench. IMO a better shooter could shave a 1/4 inch off my groups. Just had a measuring tape with me so groups were not precisely measured.

First up was a new lefty CZ 527 in .204 Ruger. Mounted a Sightron 4x16 scope on it with the rings that came with the rifle. Ammo was Hornady 40 grain Vmax. After sighting in at 50 moved back to 100 and finished with two, three shot groups that measured 3/8 and 5/8. A keeper for sure. Bought the ammo online for under $18 a box so not sure if I will even reload for it. Rifle does not like to lay on the rest without being snugged up.

Next up was a new lefty Stag Arms 6L .223 Super Varminter. I have a Bushnell Elite 3200 4x12 scope mounted on it and was shooting some left over reloads from my Savage 110. 52 grain Berger bullets over a medium charge of Varget (which I don't have any more!). After sight in went back to 100 and pretty much every three shot group I shot with it was running on average 1/2 inch. It makes sense to me now that most shooters are getting away from bolt actions for varmint rifles and going to the AR platform. I would bet with ammo tailored for the rifle it would shoot consistent 1/4 inch groups at 100 yards. Much easier to get follow up shots on running critters with a semi.

Finally brought out my lefty Stag Arms 4L flat top that has a Zeiss Terra 3X 2x7 mounted on it. Used the same ammo as I did in the Super Varminter and it was shooting a consistent 1 inch or better but the wind was starting to kick up. Still, pretty impressive as it doesn't sit on the rest very well.

Good report, Snowwolfe. Always nice to have a good range day with some toys. I recently considered buying a LH 527 in either 223 or 204 but went a different route. Good to know they are the shooters their reputation makes them out to be. Seems like a great little walking varmint rifle.

I don't currently have any AR's but one of the "L" series Stags has been beckoning me for a while now. Do you have a preference between your two?

If your looking for a rifle that is super accurate and you will not be carrying it that much go for the Super Varminter. Great trigger right out of the box. But it is heavy! Mine weighs 11 pounds 6 ounces scoped and empty.

The 4L is shorter and lighter and easier to carry around.

Just depends on your intended use. I bought the 6L to replace two different bolt action varmint rifles and am very glad I did. You can find them online at just under $900.

Congrats on some solid performance from your new rifles. I wish I could say we got similar results with our new Stag Model 6 Super Varminters. While mine showed decent potential (factory Prvi 75 gr Match HP), my son's was mediocre, struggling to get close to MOA, with most 5 shot groups between 1 1/2 and 2 inches at 100 yards off sandbags on a concrete bench. He was pretty disappointed, as his old PSA carbine shot that well and we were hoping to do some long range work with these 24 " heavy barreled AR'S.
Any suggestions for loads that might approach Star's 1/2 MOA Guarantee?

The only load I tried was:
Remington brass, Rem 7 1/2 primer, 52 grain Berger bullets, 26 grains Varget. OAL was 2.260 inches.

I know what I am going to say is out of style but IMO a lot of these rifles with the faster twists (the 6L has 1-8) actually shoot the shorter bullets really well and it is more easier to find a accurate load with them than the longer heavier bullets. I base this on limited experience with only three .223 rifles and talking to others shooters at our local range who share similar results. Bet if you can find some Berger 52 or 55 grain bullets you will find them to be very accurate.
