....what you experienced is unfortunate.
....my experience with handloads @100 yds (lasered) to determine pressure was the opposite, I'm not sending my barrel back
For reference - a couple OCWs with 105 Bergers over Varget and 58 VMax over xbr8208. 18" proof Carbon. Shoot well under moa with both 105 and 108 factory loads as well. My 12.5" Faxon prints into 1.5" with 105s and 2" with 108s at 100 for 10 shot groups. My barrel started to group consistently at about 50 rounds down the tube.
...that particular group was the max Berger 95 VLD load and the 67th, 68th & 69th round of 113 rounds down a brand new BA 18" barrel. It was the 1st time out for the build. I have not been able to get any factory ammo so I went straight to handloads. I only use factory ammo to validate a build and establish baseline data. If you scroll back in this thread my results from that day are posted. The focus was testing powder charges for pressure, not accuracy, ensuring the bullet passes over the optical sensors of my old chrony, having an aiming point down range helps to keep that bullet as centered as possible over the sensors. Pic I took waiting for the rain to pass, had to bring chrony under the canopy.
I ordered it the end of December and they quoted 12-14 weeks at the time of order placement. I received it in the middle of February. They beat their quoted lead time significantly.
Thanks for the kind words. Yes, that series on the 6.5CM BA barrel was fun and turned out some nice results for a relatively cheap barrel that a lot of people frown upon, but I was happy with mine. I special ordered this 6mm ARC barrel and was quoted a 12-14 week lead time. They delivered it in about 6-7 weeks. I was able to take advantage of their sale, I believe it was 20 percent off, which brought it in around 280 bucks. I also ordered a LR-308 barrel at the same time and both were delivered together. That build is coming in the next couple months.
Thanks. Yes, it is truly customizable. I went with a 20 inch, stainless steel, 1:7 twist 5R rifling, bull contour, rifle length gas and standard length gas journal and 5/8-24 threads. The specs are also shown on the card in the second pic in my post. No other options.
Ah, ok. I did not notice, my apology.
Just curious. Where did you hear that about the Hornady ammo?Ah, ok. I did not notice, my apology.
Interesting twist for the hornaday ammo. From what I’ve heard, no less than 7.5” twist rate should be used for that ammo. However yours seems to be shooting nicely.
I’ve read it a few different times in some online LR groups, don’t remember exactly which ones.
Well, since 7 is more (or faster) twist than 7.5, it makes sense.Interesting twist for the hornaday ammo. From what I’ve heard, no less than 7.5” twist rate should be used for that ammo. However yours seems to be shooting nicely.
Are you using the 6.8 PRI mags?
Yes. I think they're 10 round 6.8 mags. I only load them to 5 for the 6mm. I also did a fair bit of mag lip tweaking and sanding/polishing.
I don’t think there are. Brenton has pushed the width to the max which is what the Grendel case needs. My PRI 6.8’s don’t work very well cause they’re to narrow inside.
We already have the mag ban bullshit here in MD.
What rifling do they use in that barrel?
Not sure. I believe it’s just standard button rifling
6 groove I’m assuming then
I just ordered some Geissele 15 and 25 rd mags from Brownell's. I believe this is the first time they have became available anywhere. They have a stainless steel body and are black oxide coated, and have their 6mm ARC tweaked followers.
Or a couple gallons of gas. lol
