Go higher power/smaller reticle...

Shoot a bigger target/aiming point.

Gun
Range
Groups.


Gun Core 30 308 ammo 168 otm . SSA factory think the load was 41.5 gr of sm 749 BR2 primes. Scope is 2.5 x8 m4 mrt. Group 1. 2.140. Group 2. 2.113. = ave of 2.126 ? Do we -.308 or not then the ace would be 1.8185"

You can and really should subtract the difference of .224 vs .308, but not subtract a full .308.

That way center to center of all shots is the same.

Same way we used a step up plug to plug .224 shots up to 308 in highpower for some time. Made sense. but then they decided the .224 was better and easier to shoot, so it was back to group size period.

But then again are we subtracting anything from .224 groups?

About to pour here, so I'm done for any chance of shooting this morning at least.

well what the heck, I might as well play, though the leaders be safe

Daniel Defense Mk12 with 18" barrel. Exchanged the SSA trigger for a DMR, and changed to a Magpul STR stock. Loopey VX-R 3-9x40 in American Defense QD mount.

Load is 77gr Tipped Matchkings over 24 gr of CFE223 and CCI 41 primers, seated to mag length. Brass was brand new Nosler brass.

The rifle:



the range



It was threatening rain all morning, and the wind was variable, But the first group was 1.44", and the 2nd was 1.62, for an average of 1.53"



I suspect the rifle will do better, especially after tuning the loads a bit more...and the shooter learning to shoot better...

Anyone shooting LC brass anymore or is it un obtainable?

We never shot anything except LC and RP nickel one time for another reason.

LC has given me all I ever needed for accuracy while remaining reasonably priced.

I found my lot of new LC uncrimped brass stash last year, loaded 1000 rounds and stuck em back. Started shooting them yesterday.

LC brass is my top choice but pretty much anything other than federal I have been pleased with. Just shot the last of my virgin LC brass today, time to get more I guess.

fredIII,
Yes, group size is measured center to center for this. Those .308's are hard to tame aren't they?

tex_n_cal,
Nice shooting. I have been tempted to try the 77 TMK's but have been holding out to see how they perform for others at magazine length. It looks like they have a secant ogive like the 75gr Hornady's so I wonder if they are picky about seating depth.

Fred should get bonus points, cause he shot his upside down.

Y'all finally got to me. Not at all what I wanted to do,IE shoot off a bench, but it quit raining long enough, and forecast through the end of May we likely will have rain chances each day. Water on the range so I didn't grab the mat, so I cheated and used my deer rifle light front rest and bag back and shot the dang thing off a bench. I really feel better in the sling prone, but it is what it is.

Of course when I had time to get to the range, the sun was gone behind a cloud, late in the day just now. I boogied in the mule and left at 725 from the house, drove 300 or so yards, stapled 2 targets(yep I found em, finally) up, went back to 110 yard bench, and cheated again, you'll have to throw em out or whatever, but the gun was never fired at 100 before... I took 3 sighter shots, to get more or less to center, then fired 10 rounds. I pretty much suck it seems. No shooting irons in 11 years. Old mixed ammo 75 amax with cracked necks, mixed primers and cheap surplus powder.

First group when I toss out what I know where sighters, and one was a 10, the one in the white you can see, the other two are a low 9 around 7, the white circle has black mark to show it was SS2, and the other a 10 around 10 oclock, it has a black mark on the circle either side of it.

Put the spotting scope down, and fired 10 rounds as fast as I could load and squeeze.

Checked that group, gave the second up and right and again proved I can't shoot much anymore and dumped 10 more down and drove down.

Back at home at 738.

Looks like about 99-5 and 99-3, I didn't dig out my scoring plug, and did a fair CT to CT measurement of both groups. 1.266 and ughh ughh 1.565

I can say this much, my old RX for the eyes isn't right anymore. I needed a bit more light, and of course as I drove down the sun popped out for a few minutes....to get the targets down... to late.

I'll play this again one day, may try to get some of the other ammo I have in cans and shoot some of it.

With cracking necks and such, none of it will be all that great but certainly I should be able to get a pair of groups down around 1 inch or under I'd hope.

Emailed my pics to the wife, she'll get em on photo bucket sometime, I'll post the pics then. I forgot to look at rules but have the gun/bench and target in one, and the targets in the otehrs.

If I can remember not to pull the trigger until the sights are just right and blink off the bad sight pictures and use a scope to check every shot, it should get better.

Please bear in mind the targets were shot normal orientation but I wasn't paying attention trying to get a photo you could see the calipers on better so the angles were weird..

So you can see I'm not scared to show how rusty I am.

That is incredible shooting.

no, thats far from incredible. There are many folks much more talented.

bit of info on the rifle before I crash for the night

Holliger built of course, upper has a 7 twist Krieger SS on it. Has a lot of surface rust on it from a wet run where we didn't get them dry well enough before a 2 day drive home... bore was oiled though, so as I often say, its not the outside but the inside..

Rear sight is hooded, Holliger, 1/4 x1/4 pinned. Hood might have a 052 in it right now I didn't check. Front is milled and 037 wide, IE skinny but has worked for me well. Wife had to have a wider one, 050 IIRC.

My front sight is same aparent width as the aiming black at all ranges.

Floated with RRA tube. Lower is an old colt sporter with block in it, but has Milazzo trigger( how many even know that name) in it thats been really great over the years. Best i've ever felt actually. We are fortunate to have 2.

Chamber is Wylde.

Stock is A2, and might be painted in green mirage paint as we were getting bored with black, black and black.. it was one thing the rules would allow. buddy has one in TX flag colors, I still have white lowers I want a few blue anodized as the wife loves blue and her plastic hardware was blue for a few yeras..

That's still great shooting.............

Well, if you find any let us know; I haven't seen any LC stuff virgin brass in quite a while...........I'm into my last 300 rounds that I've been using for my bolt gun.

MM

Thanks

The 24gr CFE223 is the very first load I have tried with them, and I think I may nudge the load up a bit, as well as try some different primers.

Varget with the same bullets should be worth a try, too.

I did notice if I sucked it up tighter it tightens the groups up a bunch but did not notice tell after I shot my two groups and in the spirt of a fun competition I turned in my first attempt. Great idea to have a little Saturday fun with. Thanks might try my 6.8 for 2 10 this week and see how it fairs ..

dyslexic at it's worst
