That is what I measured... "your mileage may vary"
Now, that's about the funniest thing I've read all day, but I don't get out a lot.I dunno, I'm pretty sure that Woodinville, WA tap water is made up of liberal tears. I think you have to get further to the east side of the state to get pure water.![]()
I do feel like a fish out of water over here on this side of the Cascades.I dunno, I'm pretty sure that Woodinville, WA tap water is made up of liberal tears. I think you have to get further to the east side of the state to get pure water.![]()

I came from a state where you don't need a permit for concealed carry.
I can't even begin to explain how different it is over here.
That's pretty funny too!There are most likely some mushrooms growing in your yard that will make you OK with the whole scene......

26" but it is where it shoots good not where velocity is the highest, it can go a lot more but I never pushed it 3250- 3300 it is a sub.1 gun. Jim
Has anyone ever experimented with just blowing out the shoulder of a standard 6BR to 40 degrees? No, I'm not talking about a Dasher or BRDX where the shoulder is blown forward 70-100 thou and has a 40 degree shoulder. My winter project is an Improved 6BR that has the Ackley benefits, but much easier to make than the existing improved BR's. P.O. Ackley's theory with the 40 degree shoulder and very little body taper was: better combustion chamber, more stable brass, less bolt thrust, less case growth, more velosity with less pressure. This Ackley Improved round will headspace on a new standard 6BR (Lapua) case at the neck/shoulder junction. So, there is no case prep. hassles associated with blowing the shoulder forward. There is safety issue with blowing the entire shoulder forward: this is case stretch. If not fireformed correctly, the case can stretch at the web, leaving it thin in that area. A thin web can rupture and blow brass, powder, and hot gasses back in the face of the shooter. I have witnessed this first hand: it is not pretty. If anyone can shed some light on this experiment let me know. And if you or know of someone that has a reamer or dies for this animal let me know. Thank you, Samuel Hall
I did some chrono work yesterday with XBR8208 & Berger 80gr FB about .01" longer than my touch #. 28" Krieger, 12 TW, .236" 4 Groove, .104" FB. 59 rounds down the pipe when I started. Once fired brass, Russian Mag primer, 83deg out.
30.5gr was 3,095 FPS (both FF and 1x F brass). Went all the way to 32.9gr @ 3,341 FPS and never did get pressure. I'm just gonna load 50 up around 3,275 and shoot a 300 yard clay match this weekend. At that point, my barrel should be broken in so I can start load work in earnest. I think I'm going to like this as a short range, fun match barrel!
With 8208 XBR I think the lot to lot variation is a quite noticeable in some cases. Remember it was used in the PPC. to start with and has slowed down a bunch over the first lot. It still does shoot good with the light bullet and I have had some success with the 103's with it, but I need a little more time with it. ...... Jim
