load info

[cmillard]

i am ready to purchase powder again and have been looking at imr 4007 ssc. have a .236 bore 5R 6BR and am shooting the heavies. anyone tried this? what velocities?

 

[Heavies]

The cartridge guide shows 31.5 under a 105VLD with 100% load density. Does not give velocity though.

I have seen folks report very good es/sd numbers, but dirty burn and low velocity.

I am interested to see your results if you try this powder out in a straight 6BR.

thanks for the info. i thought that the .236 bore instead of .237 might improve the burn. wishful thinking?
