still have not figured out, how to quote, but i used a suppressor because it does tighten up the groups. i have never heard of extra wear on the receiver but do understand why that could be said. and in the case of the F- class upper, to keep it locked up as long as possible the gas system was all but closed with the tubbs extra power spring and extra weight of the operating system there was, i would think less stress on the receiver than a carbine gas system with the Same ammo. it was also a true side charger with charging handle or a place for one. but really just saying how i set-up mine. also just a note if you do show up at 1k match with a 20" 223/5.56 using store bought ammo be really for the looks of horror from the other shooters and them saying more or less it can not be done safely, till you prove yourself. i will try to get W to post a picutre or 2. The QUOTE button is on the upper right corner of the post to the right of tthe heading. The stress of extra weight on some cans with long heavy barrels can be detrimental to upper receivers. The right factory ammo will do 1000 but anything less than the 69's will not and the 69 is really getting stretched at 1000. That pic of your rifle is very nice. I don't have a lot of termites eating my hand guards but that doesn't mean I won't. I'm putting all the weight we can get in the barrel and will load up the butt stock to the total package of 18 pounds and when I shoot F-Open we will make it the full load 22. I want to concentrate on the shot and nothing else and those heavy guns make it a bit easier. Of course that $700 front rest I'm eying would help a tad too!! Greg

Greg found it thanks, and yes that counter weight really does help, it makes a 1/4 M.O.A. difference to the good.

I have been remiss in posting on my competition effort so here it goes. I started working with my 6X45 BHW AR a few months ago. I spent a few days at the range and worked up what I thought would be an acceptable load for 500 yards. I am shooting mid-range F-Class in the Open division as this is neither a 223 or a 308. Pet load was a 87 grain Hornady BTHP over a MAX of RL15. I'm getting about 2940 with this load and it is a solid sub-MOA performer at 100 yards. They have a practice session at a local club every Friday AM and I started with a couple of those. I found the Vortex scope I mounted up was quite good for what I wanted and that the Giselle trigger made life a whole lot easier. Over the past two months my practice scores have gone up steadily. Not earth shattering but nipping at the Masters level. Shooting scoring rings at 500 is a whole different world that whacking 8" plates at the same distance where a hit is a hit vs an X or an 8!! X-ring is 2 1/2", 10 ring is 5" and the 9 is about 8". I figured after three practices I'd try a real match so headed on down and signed up. I've been going early and setting up the range with new targets etc. so I did know a few guys. The first match yielded up a 514/600 not good but not bad. The wind was a bear and I was just learning how to put it all together. I went to another practice or two and headed back for Round #2. This time I was getting the basics down and learning the wind reading a bit. Popped up with a 538/600 with 9 X's for my second effort. Better. I skipped practice this week because it was my Anniversary and after cleaning the rifle headed down yesterday. It is finally warming up and I was more comfortable at 105 vs 90. I do better with sweat in my eyes. The winds were very variable with lots of switching. Mirage looked like the outlet of the Mississippi River in New Orleans. I worked hard on the wind flags yesterday and strived to "pick" my conditions. It didn't always work but I did string s a few 10's and X's together. No threat to David Tubb yet but I did improve to a 544/600. I finally broke the 90% level and that was my goal for the day. I have been learning the system and am pleased. The rifle with 2 pounds of shot in the butt weighs 14 pounds including a bipod. Since I an in Open class I have a 22 pound weight limit with the bipod NOT attached. You can use bags and even a front pedestal if you like. I'm going to get a Sinclair bipod for a standard target class. I will shoot a 223 in but the front pedestal for Open is a puzzle at this point. I'll dig up about $500 somewhere along the line and give it a shot. If I am going to compete I'm going for the Gold. When the range moves out to 1000 yards I want all my ducks in a row. I have found that I am getting some vertical stringing and after talking to Ritch have figured out, finally, that it is time to weigh brass. I avoided doing that like the plague but I must do something to tighten up my shot strings. I'm testing some 223 stuff today with weighed brass so it will give me an indication on the effects of that little endeavor. I'll be going through my 6X45 brass once I resize and re-trim everything this week and pick out some similar + or - 0.5 grain brass and see what transpires down the road. I'm sue it can only improve things. Just a quick note and I'll post more as I play the game. Greg

Shot an F-Class mid-range match yesterday. 500 yards. 100-110 degrees. Calm to start and switching gusts toward the end.
I used the 6X68 with 75 grain VMAX at 3330. Not the best bullet but in the calm its shots VERY well. I manged my best finish so far at tad over 91%. The wind cost me quite a few points as I was missing the five inch ten ring by about 1/2" on many shots and it blew out a few 8's on the last 20. A better bullet, like a BERGER 95, would shoot through conditions and let me get some nice "free" points. Maybe when the Social Security check gets here on the 15'th I'll go buy a box and try them out.
I know that the 243 LBC that is in the works will let me shoot abit longer bullet and the case deign will let me smoke 'em a bit. That ought to be the perfect trade off.
One thing that did happen was that in practice on Friday I lost the parallax on my Leupold 24X target scope. Luckily I was heading out on Saturday to go shoot so I took one of my Vortex scopes off and remounted it so I would have some good glass on Sunday. The Leupold went Priority Mail to Beaverton and I juts got notice it was deliverd this AM. I'll have it back in my hands by a week from tomorrow and have it up and 'running for the match the next weekend.

Greg I shoot a custom 308 as heavy as possible. When practicing I use a muzzle brake but use a weight comp on the end of the barrel when shooting comp because as said no muzzle brakes.That comp on the end helps keep point of impact the same as the brake.I have seen AR15 being used in competition and they do very well with 69-77 grain pills.I am the odd ball out there because i use a bipod & rear bag instead of the front mount adjustable stands that most use.I was thinking of building a 6.5x6.8 ar to compete in the open class. Less recoil means less fatigue which usually means a better score. Good Luck on your adventure!

The 6.5X6.8 should do well in the Open class on a good day. I know I intend to try mine along side my 260 Remington/Svage and the obligatory 223. They shoot just Norh of me so if my personbal life setles down I wil be giving them a run for it. Greg
