    If you're anywhere near Avenal, CA and want to try your hand the match is Sunday, registration is 8am at Avenal Gun Club. PM me with your email address if you want to go and I'll forward the range card to you. This is a walking match, 2 miles total, 800ft elevation change total. 1 shot per target, 50rds total. All targets are at least 1MOA. There are obstacle stations, no spotting scopes (shooters all spot) or shooting mats. Bipods and rests allowed but you gotta carry them so you might want to keep weight to a minimum (seriously) and remember you'll need plenty of water. There's not really any shade either.

    I've got my MVP ready to go, trigger is adjusted down to 1lbs and I've put together some ammo for the match. I even managed to fix my 20rd mag.

    Normally I shoot really long loaded ammo so I can get max velocity from a little more powder in the case. This time I'm running 22.5gn of Benchmark instead of my normal 23.9 and I've got the 75gn Hornady BTHP's seated to mag length (just). I wanted to be able to feed from the magazine for this match instead of carrying my cooler. Yes, I usually use a small ice chest to keep my ammo in. Keeps the temps stable all day even in the sun. This time though I'll only have 2 mags to carry which is easier to deal with on the walking matches.

    Begin terrible picture. This is 100 rounds and a reparied mag. The 30rd mag stays with the gun.

    And the rifle. The big differences on it lately from the pic below are the addition of a 3/4" cheek rest and painting the scope and mag and cheek rest in a light desert sand color. I think I'll do it to the pistol grip too. Good way to burn some time tonight.

    I put my bore:scope collimator on the MVP and my Savage 10FP; both are wearing SWFA 16x42's, and noticed my click values seemed to be registering .5MOA on one of them. That might be due to barrel length but I'll need to do some verification tonight and at the range soon and possibly update my calibration data for that scope. That ought to be fun but it's not what's really pressing. I've got plenty to do before the match. One, this is a new load and it's mag length and the rifle loves to drop flyers if I don't jam the bullet into the rifling on most mag length loads so we'll see how it does with this recipe (thankfully any recipe I make really consistent it'll shoot pretty well). Two, I have to chronograph the load before I can generate my DOPE which means I have to use KAC BulletFlight instead of BallisticXLR print outs which I hate to do. Three, I have to get a zero and then run confirmation shots at various ranges. And, I have to do that all between sunup and 8am and today I get to recalibrate my Kestrel since it's been about a year since I've done that.

    Yay. Another match rushed into with too much to do.

    Thanks for the real-world pre-match report, SpamA. For those of us who haven't ever taken part in organized matches (or even dis-organized matches:D), it's a chance to get a glimpse into a small part of getting prepped for a particular competition.

    For instance, through the magic of the interwebs, if I were ever to consider participating in a shoot like that, I can find out right now that the weather for Avenal on Sunday morning from 7a-3p should go from

    Temp: 43°F --> 67°F
    Wind: 2mph NE --> 10mph NNW
    Barometric Pressure: 30.21" -> 30.25" -> 30.18"
    Humidity: 93% -> 32%
    Precip or Fog: relatively nil

    But how any of that data (and keeping track of it as it changed) would translate into a choice of load, equipment, supplies or strategy would be just a guess the first time out or two.

    Best of luck, and waiting from my arm-chair for the post-game on Monday;)

    I don't suppose any of you are carpenters? I'm looking for some tips. I'm constructing a segment of roof but at ground level. It'll be more like a lean-to with a section of over-hanging roof on one side (think just far enough to make bipod use difficult on the far side. The normal truss design needs to be cut off on one side but I'm worried about shear loads and bending loads. I'm curious if anyone with some skills has some tips. We're looking at a 4'x6' (wide x long) back side and a 2'x4' overhang and we obviously are going to have people crawling over it all the time and high wind loads will occasionally batter at it. I was thinking I could do one side in the traditional manner with a king stud running between the bottom chord and the peak and a K shaped set of struts on the front going up to the overhang and down to the bottom chord and top chord from the king stud and perhaps running another vertical from the bottom chord to the overhang in front of the strut. I guess it'd look something like /|K| (carpenters will get the idea) with a proper peak and overhang added.

    I've done a few projects but I'm not a pro. Your concept seems to be a good one. I'm not sure what kind of wind loads you are looking at though. The uprights might also require a post hole digger and some cement too due to the over hang you want. Part of the reason I ask is that you may be able to use 2"X3" for the supports and 2"X4" for the roof structure. I would run the angled part of the K structure out to the center of the over hang for the support and have the lower angle pick up somewhere on the upper angle to give it a bit more support. How far you can go out will depend on the height of the thing. I'm the type that likes to draw out a plan to scale before I build it to make sure what I want to do will actually work. So far, nothing I've built has failed.

    Wind loads are from mild to strong 0-35mph. The big issue is that the winds there don't have a favorite direction. We planned a gap of about a foot between the slope and the ground to let water and wind move through. We've got a post hole digger and a couple 4x4's for the king studs and some cement staged up there. That's a MF by the way, there's not much in the way of vehicular access so we have to carry things like 5-gallon jugs of water to mix with the concrete. I was planning on using screws instead of nails but it occurred to me that running everything on single shear connections with lag bolts might be a better idea.

    One foot. That's not a lot of room to work.

    The K would be at a pretty extreme angle but with 2X4s, it should still be doable. The lower angle on the K might need to be positioned about 1 foot out on the upper angle and the upper angle ran out to about mid-point on the over hang. With cross braces between the sides every 24" should give enough rigidity to provide a solid enough platform, support a person and rifle, and withstand the wind.

    Lag bolts will work but I think #8 deck screws in a triangle at each joint work be more solid in attachment points.

    spam: How did you manage to get your trigger down to alb? I have backed the screw on mine all the way until it is flush, which is far as it seems it is recommended, and I am still around 3-lbs on my MVP Predator. I was under the impression these all the MVP models had the same trigger so really interested in what you've done to yours.

    DaKahuna: I replaced it. I have a Jard and a Timney. I think I have figured out how to modify the factory trigger as well but I'll have to actually do it to be sure and I don't really have a need or desire to.


    Match Results:
    I came in 11th out of 17 in the Tactical Rifle class (.308 & .223 limited gun).
    I came in 29th out of 38 overall.

    Not my best performance ever. I and the gun are capable (demonstrably) of much better. My only consolation is it's been a long time and the whole thing I approached kinda haphazardly so I achieved actually exactly what I expected which was a score somewhere near the middle of the pack. Buggery ammo, heart rate in orbit, massively difficult wind situation (shifting from 0-30, 3-5 changes inside any particular shot, canyons galore, etc...) and straight up fatigue from having built and lugged up to station 2 the rooftop obstacle.

    Squad Setup:
    We were squadded in teams of 5 or 6. Each team was started at one of eight stages, one to a stage. So we hike up from the parking lot to stage 1 and those that get to start on later stages continue to hike out to them. Once you finish your first stage you move on to the next one. In the case of starting beyond stage one, stage 7 for instance, you have to go to stage 8 then back to 1 and up to 6 then back to 1 and into the parking lot, all on the trail, to finish without a DQ.

    Interesting stuff that happened:
    I was started on stage 7 which is almost as bad as you can start out. About a half mile into the walk to our first station I realize my earmuffs didn't make it into my pack and my squad can't start shooting till all of us are at the station. Luckily one of my squad mates had a set of seriously uncomfortable foam plugs. Disaster averted at least.

    On my 15th shot I suffered a case head separation. Half of the case was left in the chamber and the back half came out. One of the guys grabbed a 20ga bore brush and spun it onto a section of cleaning rod and handed it to me, I ripped my bolt out and jammed that brush into the chamber till I felt it get tight, pulled it out and bang, stuck case removed. The case that separated did so very cleanly in a nice ring. I didn't see any sign of ICHS during the brass processing. The case did have probably 10-15 loads on it and most of them over book. No surprise. However, next time I'm bringing a 20ga bore brush and a length of cleaning rod.

    The team in front of us seemed to peter out a bit after their 4th stage and they were constantly 10 minutes longer than we were at any stage so we got a little rest occasionally if the trip from one pit to the next wasn't too long. When it was long we arrived out of breath and were almost immediately on deck.

    I cranked out a little video for y'all's entertainment. Enjoy!

    Dang; reads like an exicting day.

    The rotation you described begs the question: who got the best starting point....?

    We did similar stuff in the military competitions; starting with a jump from a helo, then force-marching from range to range, firing different types of weapon systems.

    Good memories.

    Addendum; the memories of not being able to catch my breath surface to the forefront in my mind..

    There was only 1 perfectly good starting point, station 1. That was all done by a random drawing though and even the organizer/match director ended up starting at station 6. What really makes me happy is that after a long absence from belly crawling that I'm still able to do it at a reasonable level despite still recovering from being a heavy smoker and being out of shape. Huffing and puffing and racing heart rate is terrible for the precision but I was able to pull it together, focus and control my breathing which helped to pull the heart rate down from 140 to a more manageable 120. The uncontrollable sweating on station 1 was a little rougher. Sweat mixes with dirt to make a sort of thin stinging mud that always finds a way into your eyes.

    It was really one of the best times I've had shooting in a good long time despite being so rough on me. I'm still sore as hell.
