Home Forums Hunting & Shooting AR and Tactical Rifles 24HC MOA All Day Long Challenge

Holy Fugg BSA, did I cheat? my Swede wears a Shilen, guess I missed that in the rules layout, I'm gonna have to re-shoot with an iron sighted Sharps rifle.

Because you gotta run down and mark the target after every shot! Duh!

A little shooting yesterday, cold (40* F), calm and 100 yards with a slight incline (maybe 5%).

First up, my new Ruger American in 7.62x39, with SWFA 6X MQ. Left group with factory Hornady 123 SST steel case ammo - 1-1/4". The right with Silver Bear 123 Soft points. Both five shots. Looks like Hornady wins.



Next was an experiment with 69 TMK and 75 BTHP in my 223. I wanted to do this with Benchmark, but none to be found locally.

So, I had some new Remington brass with federal primers laying around, and decided to see how Stick's load of 26.5 Lever would shape out.

The right group is the 69 SMK at 2.255 OAL, and the left group is the 75 BTHP at 2.225 OAL (same length, case base to ogive). Both ten shots.

I'm going to load the 75 BTHP out to 2.275 (max mag length) and see how that pans out.

The 7.62x39 American looks like it has good potential.

40F sounds pretty balmy to me right now. We're -11F today, wind chill -30F.

Ha ha. Thats a good one.

Im glad to see someone shooting. Thanks for posting your targets. With some load development, youll fine tune those groups. I shot my new Tikka superlite yesterday and am so close to moa now that it isnt even funny. I was hoping to pop the moa's cherry, but it didnt happen.

Here is my submission. I'm going to say doing this MOA thing with a Model 70 in a 300 RUM is no fun at all.. I haven't seen anyone else drag out there big boomers for this shoot. Anyhow
Rifle Stainless Classic in a 300 RUM bedded, scope burris ff2 3-9x40, load 98.0gr of retumbo, FED 215, Barnes cases, 10- 180 Ballistic tip and 10-180gr NAB. Weather was overcast and 22 degrees out, I shot 3 rounds then let the barrel cool etc. My first group that flyer killed me lol. Needless to say I wont be doing this with my 300 RUM again lol

You are a hell of a man. Ive been thinking about trying it with my 7 pound 338wm. . Thats actually not bad shooting with that big magnum. Are you in the hot tub now, probably on your 4th jack and coke too.

That’s awesome 79S! I don’t believe I’d run my 300 RUM for this but you just brought the bar up pretty darned high.

Thank the lord for limbsaver recoil pads lol..

Oh she bucks pretty good, it's a big push. Nothing to make you cross eyed, but enough to make you know you are not shooting a 30-06. I chose my scope wisely something with a lot of eye relief as well.

A lot of people say they dont like the eye relief on that scope, but its one of my favorites.

Are you shooting a 223 chambered AR or a 5.56 chambered AR? Also that OAL is that base to tip or base to ogive? Im seating mine at OAL to 2.255 When I measure my BTO, I zero out my calipers with the comparator on and my BTO is 1.850.

The 69s were 2.255 OAL, the 75s were 2.225 OAL.

I didn’t change the seating die between bullets.

I have some loaded (75s) to 2.275 and will try them soon.

223 AR.

Are you going to single load the 2.275" loads?

I'm working toward's popping the moa's cherry with my Tikka.......!!!!!!!!!



Whether I like it or not, I'm going to load these to .020" off the lands (@ 2.915"), my next range trip. Screw the Savage. Well, at least until I get my new scope put on it..

Nice!

I have a Montana Rifle Co in .300 RUM, it's a very fine shooter. We'll see what it can do.

If he has stainless asc mags you seat bullets out too 2.300. So no need to single shot them. I will say David has them 75 seated way too deep even for 223 service rifle loads. I'm finding 2.255-2.260 to be a good starting point. I do know if you are loading 77 Sierra otm black hills is seating them too 2.247 in their mk262 mod1 loads.

Also I'm getting best results with wsr primers. I tried all of them except Fed 205. Internet lore says cci450 are the same primer as cci no41.

That's good info. I generally just run everything at .005" under mag length, which puts my oal at around 2.255", like you guys are running them. In an AR, it always seems to produce great accuracy. However, I guess if you can seat them closer to the lands your accuracy would probably improve.
