Some of you guys know I shoot a 24" heavy barreled AR for distance

Well I've been struggling to group well with 69gr bullets in a 1:9 barrel.

 

Well I think I'm there. It was ungodly windy and I may have introduced some error.

 

But here's the rifle and group.

Most impressive Frank, but you pulled the old gun magazine trick - shooting groups of less than 5. At least you went 4 rounds, most magazines rely on 3 shot groups. What was the CtoC dimension of the group? Really very nice - just couldn't resist bustin' on ya. I think I recognize that as a Sightron scope - which one and what power did you use to shoot the group?

 

Adios,

U shoot into the future 9/9/13 lol nice shooting

Bobby - No trick...LOL I had so many available matched cases and needed to load four different loadings plus I'm mega cheap! I figured 4 rounds was definitive enough for me.

 

CtC I didn't measure as this was obviously my best load and wind sux.

 

That's a Sightron SII 6-18 I think. I'd have to look at it

 

Being the purist you are I'm going to make you wretch.... With a little more work and I want to shoot with the benchrest guys to brak their balls.

U shoot into the future 9/9/13 lol nice shooting

 

That's the trick It's all about Zen

If you are struggling to make 69s group, why not try some different bullets or powders? I know that 69s are the 168s of .224's but there are a lot of other good options out there.

The Sierra's are the third bullet I've used. I've used Hornady Match and Bergers as well. I like this powder. and If you're suggesting a change in bullet weight...I want a heavy bullet for this use. I've already developed very successful loads in 50 and 55gr bullets.

What I mean is try different weights, different profiles, and different powders, in the same range. Maybe try some 70gr, 72s, whatever you can find, if you really want 69, ty every profile of 69 you can find. You may like the powder but I like chocolate even if it makes me fat, so sometimes I just have an apple. Falling in love with a component happens to all of us but sometime it is counterproductive.

 

Of course given the current unpleasantness, my advice is mostly philosophical. If those are the components you can find, you do the best you can.

Nice looking setup, Frank!

 

If you're looking at only going out to 100 with your 1/9 barrel, you might want to try the 52/53gr match bullets from Sierra or Nosler.

As a general rule, my fellow across-the-course (200-300-600yd) shooters don't find an advantage using 69gr at only 100. Sort of a waste from a cost standpoint, and it makes it tougher to stabilize out of a 1/9

Match guns are generally 1/8 or 1/7 twist to allow use of up to 80gr pills, which buck the wind out to 600yd much better than 69s

 

And speaking of wind, it was a real challenge at Cumberland on Sunday, especially at the 600yd line. And a lot of fun too!!

 

Keep up the tight groups, my friend

Vlad - Yes stay off the chocolate...LOL

I shoot W748, CFE223 and Varget routinely. The reason I shoot the 69's is the heavier the bullet the faster you have to drive them to stabilize and you know the deal.

 

Thanks for your encouragement.

NJGuy- the reason I shoot the 69's is I shoot 300 routinely and the 55's just blow around too much. The 1:9 is what I have and have though of changing it. But it shoots 50-55's so nice for chucks.

I've been testing with Varget, RL15, 69gr. Barnes Match, and 69 gr. Nosler HPBT. The best I've been getting is 25gr. Varget under a 69gr. Nosler HPBT. I shot a .182 MOA with this load.This is from a stock Rem 700 SPS Tactical 1/9 twist off a rest. I've been shooting 3 shot groups to reduce stringing. I'd like to try some Sierra's. Let me know if you want to trade some Sierra 69gr MK's for some Barnes 69gr Match.

 

I've had good results with the 69 MK so I tried the 65 Gameking for s&g since it's a bit cheaper and made for more reliable expansion. Maybe they could get you off the bleeding edge of stability.

 

the meplats are kinda ugly so measuring COL varies but the ogives appear pretty uniform
