Noveske Ar10 barrel owners reloading questions?

[StockDog]

I am trying to tune a load for my 18" ar10(Armalite).

What load is working best for you? I am loading 155 amax and 175 Amis with varget and RE15.

I am having very good results with 43 re15 behind a 175 smk in my 5r 700.

What is your typical length to the lands?
OAL length and length at the ogive?

Any help will be appreciated?

I have an 18" Noveske barrel on my Armalite-pattern AR10 as well.

I use Sierra 155 Palmas and also 175 MKs with Varget powder. I believe 46.0 gr with the 155 Palmas - don't recall the charge on the 175s - probably a couple of grains less.

I load to < 2.800" COAL (not to ogive) to ensure function in the magazine.

I consistently get sub MOA groups with this combination.

I've tried 168 SMKs as well - all match loads that I have tried have shot sub MOA from this barrel and all have had COAL < 2.800".

For that matter, factory Winchester 150gr power point loaded ammo groups right at 1 MOA.

It's pretty good barrel.

I have some some tuning on the upper and gave it a good cleaning. I will get some loads together tomorrow and shoot it. It has shot some nice groups in the past but not wuite to my e pectations.

Thankyou for your input.
