I know! Right? I try to get in a sandwhich, or a few levels of Angry Birds/ Plants vs Zombies between each shot and that automatic death machine just feeds the next round into battery without even asking. Totally ruins my zen.

I actually try to run through the mag pretty quickly most of the time. As soon as the scope settles back on target I'm putting pressure on the trigger for the next shot. Figure about 2 to 3 seconds between shots. Had one of my bipod legs cave in some small animals burrow last time I was out there. Suddenly my point of aim shifted about 40 mils low. That tends to throw off a a good rhythm between shots

I might have missed it but I did not see any recommended loads using 2520.

I use 24.1 grs. and all I can say is it has excellent accuracy when shot from 16" barrel OBR and 20" barreled Stealth. Both have wylde chamber and I use nato spec. 556 brass.

Just surprised not one mentioned this load or something close to it.

I really need a chrono after reading through this thread! I ran some function tests on 10 rounds yesterday and had some horrible groups at 100 yards. 5 rounds of 77gr SMK w/c, no crimp. 5 rounds of 77 gr Nosler CC. Both using same LC '12 brass and 23.5gr of varget. Seated close to mag length with ogive of 1.888.

Either my barrel doesn't like these pills or I screwed up somewhere. Wont know till I get a chrono.

Try running an OCW test with your loads.

24 grains and 2.245" length should be near MOA. That's about the best I've gotten with those bullets. Hornadys and Sierras both grouped better for me.

It's too fast to do really well with 77gr bullets.

Good to know. It did well with my 55gr stuff. I was going to start load development for my 1:7 16"ers and 10"ers with it but glad I asked first.

Probably try my IMR/Varget like everyone else.

Here's my 3 shot group with 77gr Nosler CC. 4th shot not included was due to the wind gust that moved the target. Guess I had to "season" the barrel.

18" BCM SS410 barrel
Nosler 77gr CC
23.5 grains of Varget
'14 LC brass
CCI 41 primers
Seat depth to 1.887 ogive

? on load, are these too hot of a load

Working on 223 load and wanting to see what my rifles like the best.

2 barrels
18" criterion 1/7 twist
20" JP 1/8 twist

Bullet: 77 gr Sierra MatchKing HPBT
Primer: CCI 400
Brass: LC
Brass Trim: 1.750
OAL: 2.256 - 2.258
Ogive: 1.875

Powder: Hodgdon Varget

Loads I am looking at are the following:

22.5, 23, 23.5, 24, 24.3, 24.5 & 25

THe Lyman reloading book is the only manual that states you can go up to 25 gr of Varget.

Is going above 24 gr of varget too hot of a load with the above information?

Thanks for the help,

Chad

I've gone up to 24.6 gr of Varget behind a 77 gr Nosler CC projectile with no pressure signs whatsoever using LC brass. I'm planning on going up to 24.8 gr next in search of that perfect load. Rifle was my SPRish build with 18" WOA SPR barrel with 223 Wylde chamber. However, YMMV. Always work up your loads in YOUR rifle and don't just blindly use someone else's load.

24.5gr of varget will be all you ever need with bullets up to 80gr in weight.
