    300 PRC update

    Great insight.. sounds like a great lesson on shortcomings of both distance measurement processes. Sounds like the electronics are more accurate, when the conditions allow the to work, manual calc seemed to be close, not perfect but less dependent on conditions? looking back what was off on the...

    300 PRC update

    That is very interesting, thx for sharing. cool to see the tightest group was in between two other shots that are fairly open groups. Looks like your foulers did really well. I think I would pick Stt#1 because the ones adjacent are also very great. I never did mess with the tuner on mine but the...

    New 6mm Advanced Rifle Cartridge

    Wow, that is awesome. I was looking at the ARC offerings earlier this year, but there was a wait time (understandably) for the different cartridge I wanted 300PRC... I tested a few rounds yesterday. I had a couple feeding issues with some of them, and the 108EH didn't seem to be as accurate...

    New 6mm Advanced Rifle Cartridge

    That seems like quite the challenge with great results. Tuning everything all together. Having not shot ARs much before this I didn't think recoil tuning mgmt was that much of a thing. Then I started landing double and triple hits at 600 and 750 with shots at 1k and yeah it definately matters. I...

    New 6mm Advanced Rifle Cartridge

    ^^ All good info on temp stability of Lvr, thx for sharing. Is CFE 223 or pp Varmit more stable than Lever? I have some sta-ball that is reserved for the 6.5?

    Mandrel Musings

    nice continuation of data. thanks! I've recently become bored and started neck turning (was previously annealing and mandrel sizing already). One other thing I've started doing is inner neck honing. It seems that annealing leave a reddish/orangeish oxide on the inside of the case. I wire brush...

    300 PRC update

    Did you run the new AMP update for the 300PRC aztec code. I just got my machine but was advised to update which I did. I ran the 300PRC today with H225 over 7828 @2900, wind was hell, but I got some good hits out to 750. I am going to run Berger 230s next. I was able to spot hits and splashes...

    New 6mm Advanced Rifle Cartridge

    3.5 thou is my bump. This makes the most sense to me, 2600-2650 for 105s out of a 20" barrel with reloadable brass that shoots to 1000yds is way better than I ever dreamed for my first DMR build - any faster for this setup may be just more trouble than it's worth. All my previous loads have...

    New 6mm Advanced Rifle Cartridge

    I was hoping the reduction in tension would help even out speeds. When I turn I leave enough to still see some low spots on the necks. I may tune the gas block a bit. It seems that it is tuned to lock back on empty mag but that's a thing to re-check. I've used other powders and got top speeds...

    New 6mm Advanced Rifle Cartridge

    Using LeverEvolution shot some test batches (with match brass prep, neck turning, inner hone etc..) and in general I couldn't really tell a difference in accuracy or velocity numbers (in terms of max speed or consistency). no target so had to shoot @ rocks on the 200 yd berm, whatever, I still...

    New 6mm Advanced Rifle Cartridge

    seems like very good detailed data. thanks for sharing. I have some 108 EHs loaded up to try. I took a sack full of rifles to the range the other day but it started raining so pistols only. I have 3 loads working on with new match prepped Starline brass (AMP annealed, neck turned, inner honed...

    300 PRC update

    I just got an AMP and have been annealing and turning some brass. As a note, I was advised(as posted on the amp site) to update the software for proper annealing code for 300PRC. did all that. ADG 1x Fired: Aztec code result was 147with #31 pilot but not neck turned. Bought the brass fired, but...

    New 6mm Advanced Rifle Cartridge

    those are great velocities IMO for that shorty! I want to do some yote hunting if I can find a place that is more local. I hear them all around at night when the train comes by but I cant shoot them out of the neighborhood. My neighbor thinks that her cats "just ran away " for some reason...

    New 6mm Advanced Rifle Cartridge

    sweet shooting...any luck on the yotes? Any hunting yotes with 6ARC? what velocities and windage difference are you getting on the 90 vs 105s?

    inner neck honing

    Well said, Its more a question of curiosity at this point. I have a bunch of 6ARC loaded without that process, It will be interesting to compare those rounds to these with all/most other components the same. I don't think I had SD and ES numbers for those rounds recorded in the past, just Avg...

    inner neck honing

    I'm trying a few batches with honed inner necks. Light champer, poly brush, then smaller brush with fine sandpaper. There's a noticeable difference in appearance. I've noticed some reddish or orangeish oxidation after annealing which is cleaned up a bit. Anyone else tried this? thoughts?
