I've looked at Saeed's posted data, and it's a start. I want to get more than a start.
ANY load data for .223 Ack.Imp. ???
Mostly I'm looking for 40 gr. bullets and Hodgdon BL-C2 or H-335 powders. Another option is H-322. BUT I'm interested in ANYTHING you might have -- even opinions about loading this caliber.
If you're loading "Obscura Arcanium" powder and some custom machined 122 gr. projectile, I'd like to hear what you have to say.
Chrono data would be nice if you have it.
OK??? Thanks!
4000fps,will be broken with both my 23" and 24" barrels. A friend's 22" barrel,will go 25fps slower. All tubes are 1-12" twist,most are PacNor S/S SuperMatch,the other a Factory Remington S/S BDL barrel I had punched out.
30.5grs of H-335 and a moly 50gr V-Max will go 3750fps,in the 23's and 24" tubes. The 22" goes about 40fps slower.
Brass life is exceptional,accuracy phenomenal,speeds speak for themselves.
As per usual,start 10% below and work in accordance,with your particular rifle's characteristics........
His fire-forming load using a 40gr Nosler BT was 28.0 grains of H-335...he didn't list a primer but the other loads below used the Winchester Small Rifle primer...THIS WAS HIS FIRE-FORMING LOAD.
His loads using fire-formed .223AI brass used Winchester Small Rifle primers...
#1) 40gr Nosler BT.....30.3gr of H-335
#2 50gr Nosler BT.....28.5gr of H-335
#3) 55gr Nosler BT.....28.0gr of H-335
Now these are the loads listed in the magazine cited above...CONSIDER THEM AS A MAXIMUM LOAD IN HIS RIFLE AND REDUCE YOUR STARTING LOADS ACCORDINGLY....AT LEAST 10%.
I don't assume any responsibility for these loads, as reported by Steve Timm, just providing them to you for your consideration.
Pg.12,of the same Issue:
"The 40gr Ballistic Tip shot very well in the rifle. The best load with the forty-grain Nosler BT is 30.3grs H-335. This combination gave an average instrumental velocity of 3900fps and shot four five-shot groups that averaged .42". Chamber pressures appeared to be mild,so this load should be a fine one for shooting prairie dogs in all temperatures.
At 31.0grs of H-335,still using the 40gr BT,there was a very slight hesitation in bolt lift. Extraction was not sticky and I could discern no case head expansion. I know from experience,however,that these problems could occur if the load was used in hot weather. The average muzzle velocity generated by this combination was a speedy 3960fps and it shot a .45" aggregate. the basic value of this load is that it clearly defines the upper bounds".
In regards to 50's:
"The fastest SAFE load using 50grain bullets was 29.0grs of H-335. With an average muzzle velocity of 3672fps and an aggregate of .39",this would be a great field load combo". It goes on in excerpt:"I would judge this load to be maximum,but quite safe to shoot in the rifle".
All his data,was through a 22" long,1-12" twist PacNor S/S SuperMatch blank.
The point being,the data I offered is of known safety in my barrels,when employing moly. You need to start lower and work up,in accordance to your individual barrel/s.
It takes more propellant with a moly projectile,to make like pressure. I'm sure you know all of that,but felt compelled to clarify.
Bottom line is,that it is one hell of a great cartridge...........
