On the eleventh I had the first decent group out of my 700P. Here is a 5 shot group at 300 yards (bullets 83-87). A few shooter issues (as always) still to polish, but I am happy with the rifle so far.
Nicely done. That would have easily earned you your long-range ticket at American Shooting - too bad you forgot to turn it in. LOL
Not a problem, you cranked out a similar group when I was there on Saturday, and then we moved on to our friend the 600 yardline.
Breezy as heck out there today (5-8 with gusts to 15 mph switching from 7 to 9 O'Clock). Miss one of those gusts and you could barely find paper from the 400 yardline (where I was doing my Load velocity testing). Ah the joys of shooting in Houston.
Jeffvn, I noticed the trees bending in the wind today and thought you must be having BIG fun on the range (I guess a bad day on the range is still better than having to work.....). Sorry I missed the shooting, but not the return of summer temps. Hope you were under the cover today. Oh, how did your load development go, find the magic combo?
Randy - no accuracy work yesterday, only velocity verification for purposes of doing powder modification in the QuickLoad program; You need to shoot a minimum 20 shot string through your chrony to verify the speeds that you get, then you modify the default burn rate in QuickLoad to meet your actual results. From there you can get a much more accuracte prediction of that particular powder's characteristics in your rifle. For me it was RL-15 through the Hammonds (26" Hart barrel 10 twist).
If people tell you there is very little to no temperature-based variation for RL-15 they don't know spit. My velocities averaged 2607 to 2634 from 9:30 to 10:30 am. (5 rounds w/ 168 Fed. GMM, 13 with load and CCI BR2 primers) Then jumped to 2645-2670 from 11:00 to 1:45 am (5 Fed. GMMM 168s + 18 rounds of exact same load with Fed. GMM primers). I obviously need to redo the Federal GMM primer rounds early in the morning - way too much temp-driven swing.
Another couple groups from the 700P today, pretty gusty so they are not the greatest at 300 yards, BUT, they are M118 LR! The lower left group was shot earlier after I messed with my scope adjustment (one inch group), then the next five was later in the day after re-zero.
Jeff gave me his old USO anti-cant device and I feel like I "cant" shoot level any more (reference above messing with my scope....). Just kidding, I really like it.
Mele, hope your Bravo likes the LR as well as it appears the 700P does, I also shot some Black Hills Match for comparison with no noticeable difference except more shiny brass and twice the cost! I definately want to get some more of that from you, I'll shoot you a PM shortly.
Jeffvn, In case you look here this evening, I ended up having to work late today and couldn't give you a call. I will not be able to make it out to the range this weekend, but will try again Tuesday morning. I'll catch up with you tomorrow.
Jeffvn and I made it back out to the 600 yard range Thursday, and I am thankful he did not have a digital camera with him. That old jarhead put more rounds in the 10 ring (15 plus Jeffvn?) in very challanging conditions than I have seen in a long while, nicely done.
But, not to let the ex-Army guys down, I was able to get my last four shots into an acceptable group, using M118LR from Mele no less (had to be the Army Sniper karma...). Group measures 2 3/8".
I did ok for once, after we got me on target. Topo's last 4 shots of the day were pretty spectacular, given our switching and gusting winds. Nothing like a breezy Houston day to humble the living crap out of you.
He is also getting damn good at reading trace, which still eludes me 99.9% of the time - maybe its my perscription - old eyes - who knows; darn frustrating when he can give me guidence through the scope and all I can do is blink and say I didn't see it.
I took some pictures with my old technology camera, and will post one or two of our shooting set-up when I get them back from the store.
Here's a nugget of information for you with the Federal Gold Medal Match 175s. When shooting at 600 yards, every mile per hour of a full value wind pushes the bullet 2.7 inches in drift. Miss a 5 mph jump in velocity and you're off the target. owning a 1/4 MOA rifle is nice, but you still can't hit the target in windy conditions if you can't read the wind.
