G'day all,

Just thought I'd share my results for some loads worked up over the weekend.
Powder: AR2209
Case: Nosler
Primer: Rem 9 1/2
Projectile: 75gn V-Max
Rifle: Ruger Hawkeye


AR2209 MOA Velocity
54.4, n/a, 3288, work up
55.2, n/a, 3317, work up
56.0, n/a, 3346 , work up
56.9, 1.02, 3418 ,
57.3, 0.98, 3504 ,
57.7, 0.60, 3478, ??? (query velocity)
58.1, 0.82, 3512,
58.5, 0.95, 3525,
58.9, 0.76, 3551,

Needless to say I was pretty impressed with the accuracy of the little bullets out of this sporter. 58.5 is the 'book maximum' so my next round of testing was:

AR2209, MOA, Velocity
57.3, 0.55, 3546
57.7, 0.52, 3571
58.1, 0.92, 3636

I reckon I'll make 57.7gn AR2209 the load for this projectile. Currently it's seated at the Hornady COAL however I don't see much of a need to change that.

I was interested to note the slight velocity increase on the different days the 1st and 2nd rounds were shot.

It was the first run with my new Nikon Monarch 4-16x42 - I'm impressed and will be a Nikon customer in the future.

Currently working up a load for the 115gn BT and AR2213SC(H4831).

Regards,
Dicko.

Apologise for the dodgy formatting.
 
Dicko -
Nice to see the velocity results with this combo. What size were the group (57.7 grains) that you decided to go with? What is the length of the barrel on the Hawkeye?

0.5 to 0.6 MOA with 57.7gn AR2209(H4350).
Very early on yet and more testing to confirm accuracy however it's looking pretty good. Each group was nice and even with no flyers.

Barrel length is I think 24 inches.

Dicko.
 
One thing for sure that 75 gr V max going around 3600 fps will have a huge SPLAT factor on varmints. Can you say RED MIST. :shock:
 
Interesting info - thanks for sharing. I haven't loaded my .25-06 with that light of a bullet, but have used H4350 quite a bit with 100 gr bullets, getting 3300+ fps from them, with good accuracy.

Dicko,

Interesting results, indeed. I was just playing around with QL, and noted that they projected quite a hotter load than the book load. Also noted the maximum charge for H4350 is somewhat less. I suppose this can be accounted for by differing lots at the time of testing. However, the greater charge projected by QL seems really significant. Nevertheless, you are getting some great velocities out of your 25-06. That looks like an excellent varmint load. I wonder if you've considered work up any loads with the Nosler 85 grain Varmint Ballistic Tip?

Good to know this information is of some assistance!

I haven't used a 'varmint' style bullet before - can't wait to see how they go.

Dr Mike, if I read that correctly, is the max load (Quick Load) for AR2209 59.5gn or 60.8?

You can bet your bottom dollar I'll be trying the 85gn BT one day soon ... the blue tips of the Nosler BT's remind me of Lone Wolf McQuade!

Regards,
Dicko.
 
Dicko,

According to the information generated by QL, the maximum charge of AR2209 with HDY V-MAX 22520 would be 62.0 grains. With the same bullet and H4350, the maximum charge is projected at 60.0 grains.
 
I'm still getting familiar with QL, but I have found that if I actually measure the capacity of my cases I can see significant differences in the data generated. I am recording case capacities in my handloading logs for future reference.
 
RR,

You are absolutely correct. The figures generated if you don't feed in your own case capacity are those of an SAAMI spec'ed case.

If that's the case Dr Mike would you say that I'm getting quite good velocity at a safe working pressure with 57.7gn?

I'm not particularly confident working consistently near max loads so I'm thinking what I've got's pretty good.

Regards,
Dicko.
 
You are getting very good velocities. Since the accuracy is there as well, I see little reason to approximate maximum charges. Your load will devastate varmints; as 1shot says "RED MIST."
 
Dicko,

Nicely done. Sounds like you have a good load.

Man, there has to be some awesome Splat Factor with that kind of speed. Can't wait to get my new 25-06! Scotty
 
Most any varmint bullet out of a 25-06 has serious splat factory. I was once given 2 boxes of Rem. factory 80 gr HP ammo by an old gentleman in my church. I though I would just shoot them up for practice and to get new once fired cases. I found that this ammo was extremely accurate in my rifle and it shot perfectly windage wise and 1.5" high with my zero of 3" high @ 100 yards with my deer hunting 117 Sierra loads. I decided to try them out on some groundhogs. Talk about a bomb. The first one I shot was right at 200 yards and all that was left in tact was just the front legs and head and the rear legs and tale section. The whole middle had been scattered in a paste for about 10 yards in the field. When I ran out of those I loaded up some 80 gr Sierra SP and they do the same thing.
 
Popped off some 5 shot groups today:
3467fps with s.d. of 19.

Pulled a shot with the 1st 5 to get 1.29 MOA.
The 2nd 5 shots went into 0.78 MOA.

Velocity down 100fps over last lot of testing, more in line with the first.

Would this much variation be considered normal?

Either way it'll defintely do me.

Regards,
Dicko.
 
That amount of variation is not unheard of. There are a variety of factors that can account for the variation. However, your SD is good and group size is very nice.
 
The velocity variation readings on different days often happens. Different sky conditions above your chrno can do this. Bright sky and cloudy sky will give different readings.
