Clean burning powder for subs (pics)

[DEVIL DOC]

H4198 left and Rem factory subs right, both shot suppressed.





What powder is (rec 7)? Is it reloader 7? I heard good things about it.

Reloader 7 may be too compressed depending on the bullet length and seating depth.

I had a pretty compressed load with some 178gr bullets trying to get them to cycle. Cleaner burning but left a good bit of completely unburnt powder in the action.

What is H4198 load?

Hodgdon H4198

Check out their website, you can print the data off.

You can find published load date on the Hodgdon site.

For a 220 you can start at 12-13gr and work down to 1000fps.

In a 9 inch AAC barrel 11.5gr is constistant at about 996fps so 11.6 may be optimal in SHORT barrels.

DD I wonder if the ES will be less?

I have been nothing but frustrated with A1680 in the BLK. It being so dirty is a sign of poor burn and variations in efficiency causing the, IMHO, huge vel swings.

I have a LB of H4198 and will try it with the 208 A-Max and see if it works.

Using federal primers my spread was very small.

With the A-Max 208 11.5 of H4198 was crunchy compressed and in my AR 16" @1049 FPS... dropped to 11.2 and that was 959? and a 1042 Will load a few more. But that's only slightly compressed.


Edit to add powder

Clarify the powder good sir. How do you like the A-max? I have 500 to load and evaluate, I heard accuracy is top notch.
