Statistics are great!

So, if 1,000 monkeys type long enough, one will accidentally type out hamlet.

Also, if you do enough load development, you'll eventually find a sub MOA group coming out of a 2 MOA rifle.

I got a 0.975" 100yd 5 shot group out of my Garand last night figuring out the velocity curve for of a new powder/bullet combo. I got my hands on a pound of I4064, which I haven't had luck with in the past, but in planning for future shortages, I figured I should get some data to expedite future load development if needed.

It's a non-bedded Garand with a criterion barrel and CMP stock. The only modifications are a match trigger job, Garand Gear gas plug, and NM sights. It reliably shoots 1.5 to 2 MOA in all of my testing to date.

This load is hot for a stock Garand, so don't use it with a GI gas plug.

48gr IMR 4064, Win LR Primer, Win .30-06 Brass, Sierra 175gr Match King. 2620 FPS

The target is an MR 31 repair center (100yd reduction of the 600yd target)

This one is a fluke, but I'll take it. What it does show is that my rifle really likes the 175gr Match Kings running around 2600 FPS, which is consistent across several powders.

I have had a couple Garrands for 15 years.
I quickly gave up on them for accuracy.

Here is a target shot with a $60 old Rem 510 22 rimfire.
I drilled and tapped for scope, and one can clearly see it is a 1" gun at 50 yards.
But notice that one of the groups is 0.15".

The monkeys typed Hamlet.

Congrats on a great group. Keep in mind though that getting a single 5-shot group with a load doesn't mean you've found the golden Easter egg. One sub-MOA group, then another, and another...now you're onto something.

Load a few more of those and see if you can duplicate the feat.

That was why I posted. This group is a huge outlier. My range for checking velocities is terrible for shooting groups with iron sights. It's a long dark tunnel with a small lit target at the end. I have to guess where my aperture is for sight picture.

I shoot 600yds to evaluate accuracy with 20 round groups by shooting prone matches and following scores, and my rifle is nowhere near capable of sub MOA shooting consistently.

That bullet at that velocity works very well for me in 308 out to 1000yds.
