Revisiting the 6 BR (Part 2)

[JamesnTN]

I decided to screw on my 6 BR that Tim Claunch twisted up for my MB action and do a little ladder test at 500 yards with it this morning. Below are the results. They say it ain't a race but damn this one is slow.

What powder and bullets?

 

[tclaunch]

Looks like it will take another 1/2 grain to get you in the 2820 range. If thats Varget, then 30.5 with 105`s wiped lots of butts in Memphis till that Brux gave up the ghost.

I have another target that went up to 30,7 starting at 30.4and it was all verticle and yes it’s Varget and 450m primers.

Varget and my Bullets

If its behaving badly, change powder asap. H4895, IMR8208, or the bad word in your vocabulary RL15.....

I don't think it's behaving too badly since it shot just over 1" in a .4 grain spread.



Here's the second target that went up to 30.7 grains.

Keep adding a lil at a time she`ll flatten out. Your getting close to the 2820/2830.

 

[comagutsa]

What chrono ? Muzzle or down range as that
But yeah i agree with ya on around 30grs

 

[JamesnTN]

Got back out this morning to do more odder testing and I think I found my flat spot for the 6 BR
These were shot at 500 yards and the chronograph used is the Lab Radar

I reckon that 16 fps spread looks looks pretty good (flat).
I'm not a Mid-Range or 600 BR shooter, so a bit of experienced dialogue is appreciated. Will you land in the middle, or work toward 31.1?

 

[tclaunch]

Work looks like it just got done, 31 gr. is looking great.

 

[KenOath]

Yep 31 looks good to go, a tenth either side should be able to shoot that load all year round.

Thanks James. I have been watching your recent posts and I think I finally understand a ladder test and plan on doing one myself. Nice work.
