You might add
4227
4895
2230C
N116

I havent got to try them extensively yet, but I think I can also make the following powders run subsonic and cycle,
Ramshot (cant remember if it was enforcer or exterminator, whichever is in the burnrate of the above powders.)
2016
Data 68
N133
3031
Ill be coming up with data for all the above and publishing it here.

Also, for those of you with a little shorter gas systems, 2400 does very well, and is quieter than the powders above.

4895 may not fit except with lighter bullets.

4227 may be good.

It would be nice for someone to do a public test with 50 round standard deviations of each of them loaded to 1000 fps.

Ive been able to get some 220's to cycle with 4895.
when I get out of the hospital and have nothing better to do in my wheel chair, I am going make an entire load data manual for the BLK with rediculous diversity, about 20 different powders, oodles of bullet types and weights, and a gell test for each one.

What would be nice is for your book to load each subsonic powder to 1000 fps, and report the cyclic rate of each one with a certain buffer. This is important because someone might report a load as 'it cycles' but it may be 600 rpm. Colt M4 specs are 700-970 rpm, and 600 will be less reliable when cold or dirty.

True, Ill get it as detailed as I can. I have a history of halucinating when on morphine for extended periods of time, this should be interesting.

does anyone have a spreadsheet started yet?

there is a ton of data being tested but one must look all over the place, it is formatted differently, and is time consuming to break down. Once I get my Barrel I might be able to help you out Aaron.

we need a standardized worksheet everyone can use to enter data and catalog. Once vetted it can be consolidated, indexed, and posted for starting points.

a big selling point is using existing gear, and consumables. A couple official loads don't help the frugal.

I was looking around the internet this evening and found that Cabela's is having a special on 1680 powder. Was $25, now $19/lb. I have to get on a plane tomorrow morning, or I would drive down to my local shop and see what they have.

I tried to order on line with local pickup but that was not an option. I will call them directly when I land tomorrow.
