Range Report of my byf 1942 shooter
 

Dear friends :
In my last post I promised to publish results of diferent Vectan BA9 charges for my 08.

here they are now:

First general conclusions:
Testing a lot of charges starting at 4,5 grains powder and going through 6.00, (using S&B sleeves, RWS small pistol primer, an AOL of 1,150 in. and light conique crimp on 115 grs fochi FMJ round nose bullet) the results showed that the increment of 0,1 grains of powder had very few influence in the velocity rate;
that BA9 is quite sensitive to atmosferic conditions ( sunny day 25 º C shots are harder and velocities higher in oposition to dark coller days , 15 to 18 º C).
After all this I notice that this was an hard task to define a nice load to my 08.

Anyway it goes next the charge and average velocity obtained:

5.0 grs = 303.15 m/s (994.59 f/s)
5,1 grs = 327,60 m/s ( 1074, 08 f/s)
5,2 grs = 328,03 m/s ( 1076,21 f/s)
5,4 grs = 329,37 m/s (1080,61 f/s)
5,5 grs = 332,84 m/s ( 1091,99 f/s)

Passing to accuracy performance , lets have just a few results, from the total shooting made handhelded at 25 meters.

5.0 grains BA9
Attachment 65605

5.5 grains BA9
Attachment 65606

4,6 grains BA9
Attachment 65607

As I noticed that higher charge would spread the shots, decided come down and teste lower charges and got the last target image.
For the moment i´m gona stay at this mild charge and watch how is it gonna do in futur shooting.

Men: this is really a long way to go, yet.

You might just want to consider using a bench rest, or sandbags when shooting for load accuracy. That will remove a good portion of the "human factor". Just a thought. Always glad to see different loads and how they perform.
