Thanks for the Add.  New to the 6mm ARC.  However, i now have over 500 rounds thru my Uintah Precision Bolt Action Upper ARC.  22" barrel length.  Been loading for the Berger 105 Hybrid Target and the 110 A-Tip.

Seems there are more trimming components for 6.5 Grendel versus 6-ARC and 6-Grendel ...

So those of you who are trimming - are you trimming before necking down to 6mm or are you seeing where you end up and using magic to trim 6mm.

I figured LEE precision would have a zip trim gauge for 6mm by now but Nope......

Old Bob here... Jumped to the 6mm ARC Forum from the 6.5 Grendel forum. Hope to get a bolt 6mm ARC in the near future. Not quite ready yet but I'm looking forward to it.

I loaded up some Hornady SST's with H380 and another batch with RL15.  With the H380's I  used CCI 450's, but just for the heck of it, I used BR4's with the RL15 loadings.  No surprises with the H380: good groups at 29.1 and 2504fps and somewhat tighter groups with 29.7 grains that I got 2547.

Keeping everything else the same, but changing to RL15 and BR4 primers, I was beating Hornady's estimated MV's by a noticeable amount.  With 26.9 grains, I measured 2577fps, compared to H's 2400; es was 30, sd was 12.  Went up to 27.5 grains and got 2625 compared to H's 2450; and the es was 10 and the sd was 4.  At 28.0, MV was 2681 compared to 2500 estimate.  The es was 5 and the sd was 2.  I'm going to have to really scrub this loading.  I'll build them the same way and check them out to see if these were just an anomaly or the real thing.  Through all 30 rounds at the different load levels, there were no pressure signs at all.

So Kotaboy32 is claiming 2600 fps from Hornady Black out of a 16" barrel. What is everyone's opinion of the likely velocity from a 12" barrel. I'm specifically interested in the factory Hornady Black with the 105gr HPBT. 

The 105 HPBT @ 2500 fps zeroed at 200 yards +1 inch looks like it will almost perfectly match the PA ACSS reticle.

Whats your opinion of Arken glass specifically the SH-4?
Im seriously considering putting one of these on my AR 6mm ARC.

Specs
4-14x44 30mm tube FFP all MRAD with zero stop and precision tracking guarantee.

For high 3??s new can I go wrong with that? Im not looking for the super premo scope here im just looking for a solid will work scope.

Went to my local HARDWARE store today , they had a keg of LvrEvolution for $ 192.00 - snagged it !

Will be trying it with the Speer 90 grain bullet soon in 6-Grendel

Starting a bolt gun build.  I have 200 new norma 22PPC cases. Can I use them to make 6mmARC brass?  No one seems to shoot or need 22 PPC any more.

Looks like a success. check out the vid. https://www.youtube.com/watch?v=GBchX_b8bTM

This video is the first I've seen someone running a c products 7.62x39 mag in a 6arc. He mentions this specifically at about 2:00. Anybody else try that?
