I usually just shoot at two local HP ranges which are reduced 200yrd ranges.
I was thinking of trying out Reade Range (PA) this weekend for the XTC match and have not reloaded any 77 or 80gr bullets yet. What can I expect out of the 69's (Yes, "If I can do my part")? The barrel is a DPMS 1:8 SS NM. Bullets are 69 smk/ 24.5gr Varget/ wsr primers/ oal 2.26.

I have some 80gr smk but no time before Sunday to work them up, let along test them at 600yrds.

Any recomendation on come-ups would be good also. I've noted other come-up's post here at 3moa(200-300) & 12moa(300-600) but assumed that was with 77-80gr.

Thanks in advance
mince

Anyone here shooting XTC at Reade Sunday?

I am not one of the big guns at Reade , but do shoot there. Load your 80 gn SMK's with 24.0 gns of Varget and seat 2.465" OAL Use your 69 gns at 200 yds come up 3 minutes (or 11 clicks with 1/4 min sights) for your 300 yd zero. Come up 12 minutes (37 clicks with 1/4 mins) for 600 and use the 80's. Those are my actual zeroes there with 1/4 min sights. I have a 1:7 now but my 1:8 was identical. Reade is a beautiful range and the targets are perfectly alined with the number boards. One thing is there are 25 firing points but the targets are 1-10, 1-10, 1-5. Be sure to swing the line with your spotting scope to make sure you are looking at point 5 and not 15.

There is a thread, about a month old, on nationalmatch.us about the exact same thing. There were come ups posted and everything.

I know the 69smk can be a viable bullet @ 600. Just pray for little to no wind.

Good luck,

Dan

+1 on the wind issue.

I've gone over to 73gr Bergers for 'jack-of-all trades' match load.

For my DCM AR, I use 77gr Sierra and H4895.

I'd run with airgun1's load after cross reference with load manual/book.

Reason: I once forgot my 80's and had to shoot the 600 with the 69's. Exercise in frustration with the wind. Chasing spotters. 80's do buck the wind much better in my experience. You'll be on paper and you get your 2 spotters to fine tune. + You'll be hooked on the 600 and want a good starting point /80 gr. to work from.

Some people run 77's for XTC because they just want to use one load and it seems to work for them.

Keep'm in the Xring

i haven't seen anyone shoot the 69s in some time at 600.
they can be a prob. in the wind. on a calm day they would be really good.
that is what was an issue before the big bullets made the 223 the best out there

Hey! Your talking Reade Range and I am a veteran of that range. 69's are not going to give your best score there. Reade is a NIGHTMARE most days!

I wouldn't even think about 69's at 600 yards there! Go with SMK 80 gainers or Nosler's 80's with a load worked up with RE-15. My load is 24.6 gr. RE-15 in LC brass and Federal 205M primers and that load isn't a given to beat the conditions at READE!

Master Reade Range and you will be able to be in the running for the National Championship!

Thanks for all your input guys.

Ok, seems like to make the trip that far worth while I better at least get some 80 smk produced. That's all I need...more pressure. lol

If it doesn't rain here in PA too much, with this storm coming up the coast, & I get some 80's worked, I'll be there.

Thanks all,
mince

If you're using a barrel with a CLE chamber you might have to back off on the 2.465" OAL.

Checked that last night. It seems DPMS has a short chamber.
The Stoney Point indicates 2.430 to the lands, so a max oal of 2.420-2.425 would be in order. I think the DPMS barrels were SAAMI.223 chambers if I recall?

I plan to compare my cases to the Stoney point case, as I think I may pick up .010 there. Wouldn't that give me a truer OAL length? Since the SP only meassures from the shoulder.

Or, I could chk them with the RCBS Mic to get the shoulder to head stamp dim. Or, am I over thinking this?

Wrangler,
If your using 80 smk in the DPMS barrels, what is your OAL? (Just to compare)

The DPMS 1x8 stainless barrel is a SAAMI spec chamber. They are shorter than the CLE, the Wylde and much shorter than the NATO chamber.

Lots of throat to shoot out in that DPMS but you have to remember this when loading your long range (80 gr.) ammo and if your like me, I load for three AR's and two have Wylde chambers!

Frank White recommends 2.435 with 80SMKs in his CLE chamber.

Mince

I have my 80 SMK's seated at 2.420" in LC brass with 24.6 gr. RE-15 and Federal 205 Match primers. They are about .010" off the lands in the new SAAMI chamber. I once shot them as much as .020" off the lands but really didn't see any difference in accuracy.

As my throat erodes, I'll seat them out accordingly.

The above load may be too hot for some rifles, so work your way up in 2/10 gr. increments beginning at 24.0 grs..

Thanks for the info Dave,

Set my OAL at 2.425 which should give me .008 off the lands. If my engineering is correct. I loaded with 23.0, 23.5 & 24.0gr of Varget w/ wsr primers. No ever-pressure signs. 23.0 & 23.5 are real close to my POI with my 69 smk w/24.5gr and 24.0gr was up about a moa. I was shooting at 200yrds.

I'm going to run with the 23.5gr of Varget. (1-x, 4-10's, 4-9's & 1-8 on the SR target) The 23.0gr did group pretty well though but didn't want to drop too low with going out to 600.

Am i on the right track? Oh, missed Reade on Sunday..family picinic day. 9/21???

Now what will they (and me) do at 600 yrds????

Watch your front sight! Read the wind via the flags and mirage. Since you have worked up a load that you are confident with, it's all up to you now!

Welcome to the sport and good luck at Reade. Master Reade Range through out any given year and you will be able to become the National Service Rifle Champion at Camp Perry!

The 9/21 match is a 50 shot match; 10 with 2 sighters Offhand @ 200, 10 with 2 sighters Rapid Sitting @ 200, 10 with 2 sighters Rapid Prone @ 300, and 20 with 2 sighters Prone Slow @ 600. There will be a league meeting and food, raffles etc.

This is the R.K. Nelson match. Usually the attendance is high for this match. Rightly so because RK was the founder of Reade Range back in the late 50's.

Shame shooters like RK are not officers today! A regular match once attracted three times the number of competitors that attend Reade today. However, only the old guys can relate to that!

airgun & Dave, Thanks for the 9/21 Reade info.

NMC 50 is what we usually shoot at Keystone at 200yrds & no sighters. No sighter...guess the "old guys" don't like walking the 200yrds any more than they need to. LOL (Since you brought up old guys) I'm just at the edge of the "old guys" catagory.

The people & sport are great. I've never met anyone in HP or IDPA that has not offered help if asked or not. I must do some recuiting for this sport at work. With the cost of the sport, equipment & ammo, it' a little hard untill you get them involved and they get a taste.
