I used to be a better shooter, a designated marksman in an Army Infantry unit.. and lots of tough shots on moving game animals. I now have bad habits, don't shoot as often, and rush shots as an example. I do indeed go from one excellent group to a poor group when unfocused, but normally can focus on fundamentals and get a good group following a poor group. The difference here is this rifle upper/barrel so far has acted a little differently regarding the shooting characteristics. I grouped averaging an inch with a light weight 270. before shooting the Grendel.
I do need to shoot more frequently at longer distances (time to shoot is exceedingly rare).
Rabbid, that is interesting regarding the lead sled. I was sitting much lower than desired, and there certainly is less room for you to get behind the rifle. I will order some Precision Firearms ammo right now. It would be nice to be able to shoot medium sized game animals farther away (Over 3-400), but at this point that's a fantasy hunting trip in another state.
A5 Blaster, we estimated with how tight his group was at 25 yards that it likely would equate to 1 moa or near moa. As you said, the problem is partially mine, as my friend certainly got closer to the mechanical accuracy of the rifle. In this day of shooting, a bolt action 270. and palmetto 5.56 absolutely killed it with extremely small groups.
Whether it is a flinch, or a shotgun shooting technique.. when it happens it certainly negatively effects rifle accuracy. I certainly do it when shooting in a lazy fashion. I switched to a mission first tactical minimalist buttstock and am having trouble getting used to it. I certainly noticed the hotter 6.5g loads with it.
That is a great idea, I will ask for critical feedback. Sometimes men hold back unless someone asks for it. I will take pictures of the target during the next shooting.
Thank you very much! It helps big time.
I will give a few more ideas too try.
If the rifle was assembled without lapping the reciver face or bedding the barrel. Then I would tear down and do that.
I also like too bed the gas tube into the gas block and bed the gas block to the barrel with lock tite. Helps remove any lil bit of gas leakage.
I also use adjustable gas and lowmass bcg's, less mass moving around means less movement of the gun.
Also if useing a free float handguard that is of a non indexing design. Depending on the thickness of the barrel, I would start my torque levels low and work up at 5 pounds changes till you see the effect.
If you have a muzzle device on the barrel take it off throw the crush washer, peel washer in the trash can and get a accuwasher set from precision armament and reinstall it with the accuwasher that allows it too be timed properly with lil to no torque.
The barrel nut and muzzle device torque is called balanced torque theory you can Google it to learn more.
Doing these things should help balance it out and improve your groupings.
