Friday, last week, I went to the range to do a little testing of some loads for my XP-100 7 SAUM.

Previously, this particular load had shot 3 shots into .56" or so at 100 meters.

This trip, I wanted to see if I could tighten up the group by changing the seating depth. To that end, I loaded the same load as before, with the seating depth the same as before as well as incrementally stepping the seating depth back by ~0.006" or so.

This trip, I would be shooting 200 yards.

The same load that previously shot ~1/2 MOA at 100 meters also shot ~1/2 MOA at 200 yards. Group size was 3 shots into .986" or so.

Then this happened:





BINGO! Just as I suspected, I was able to tighten up the grouping.

I loaded up another batch of ammo. Next range trip, I hope to confirm the grouping, and with some minor scope adjustments be "on target" at 200 yards.

I've been pretty happy with my Jon Beanland built XP-100.

milk,

that should work!

Doc

Great group!

Changing the seating depth can make quite the difference, as you've shown.

Good reason to be happy!

Nice shooting Rog!

Looks like Jon built you another shooter!

Thanks SChunter. I currently only have one gun built by Mr. Beanland, this XP-100. However, he does have my rifle (I'm waiting on a spec'd reamer).

I've got another XP I'm wanting to do something with. May have to see if he wants to convert my next one...
