Joined a local range

Interesting. Is this an outdoor range? I’m a good shot but to maintain a 1/2 moa group, even at 100 yds, is not going to happen. Shoot one group to qualify sure but eventually I would dq myself.

Yes, it's an outdoor range.

I've seen a lot of members shoot 1/2" or smaller groups.

My #4 MK I Enfield rifle in .303 British shot 1.75" groups at 100 yards with me pulling the trigger. Over the period of a year, it suddenly dropped to 1" MOA, using the same rifle and same commercial ammo.

What happened was that after a year of shooting and then cleaning the barrel a lot, the barrel became much easier to clean and smoother to push a cleaning patch through.

The barrel must have had a substantial amount of old residue and my constant cleaning and shooting reduced this enough to affect the accuracy of the rifle, because I didn't notice any improvement in my shooting technique.

When I started shooting my Savage AXIS II, I was using 105 grain Hornady commercial 6mm ARC ammo and getting between 1/2" and 1" MOA at 100 yards. When I used my own reloads using my spent brass and Hornady's 105 grain BTHP projectile, I was able to get sub 1/2" MOA groups. I use RL-15 at 26.8 grains with an estimated 1606 FPS MV. I think I may improve on that using a harmonic tuning device on my barrel.
