UPDATE:
Well been to Gander Mtn several times, never had RL10X in stock. I did try some Benchmark with amazing results.

When to Woodbury last sunday, NOV 2nd, unbelievably calm conditions for the day & that range. Both flags hanging down, maybe a slight little puff every so often.

After checking zero at 50 yards,, 3 rounds looked like only one shot on the target), I proceeded to the 200 yard range.

I was using 24.8 grains of Benchmark, all components but primers weight matched. I measured the raw group anywhere from .417 to .419 outside. .419 - .204 = .215.

.215 divided by 2=.1075 MOA, nope I hardly believe it myself, but everything clicked, it was dead calm,in the upper 60's, no humidity, no mirage. My first thought was OMG, awesome,.. my second thought was WOW, I must do a crummy job of reading the conditions the rest of the time!

One thing I know for sure, this rifle shoots a lot better than I can drive it.

When I was ladder testing the previous trip, the node appeared from 24.5 to 25.1 with Benchmark, and with H322 23.4 was the best load, but still about .1 to .2 less than the Benchmark.

Thanks again, Lester !!!

One additional note on the above results, these loads were shot from Lapua/Dakota brass weight matched and VIRGIN. It seems that neck tension using new brass is shooting a tad better than neck sized brass out of my Wilson die. I am thinking I need to tune the neck tension with a different bushing, or stop chamfering the necks. Time and testing will tell.

Any tips or questions are welcome, lets learn together.
