6br Quickload help.

[Tim Singleton]

Some help from guys with quickload would be much appreciated.
Im still saving up for it.

Info on 6br 21" barrel 66gr fowlers 33.5 gr H335
Looking for percent of burn, projected velocity?

Thanks in advance

Since you didn't list your OAL or actual H2O capacity of your cases and my QL doesn't list a 66Gr. Fowler bullet, I plugged in a 66 Berger FBHP with your load suggestion and used the default settings and came up with 98.75 propellant burnt, M.V. 3360 and 57,683psi Pmax. Default setting on OAL was 2.200. Remember QL is still a guesstimation.

I got about the same. Should be safe. But still start low and work up.Good Shooting Larry

Thanks for the info.
I'm using blue box lapua brass not sure of the h2o capacity.

Oal is 2.230".

Thanks again
this is what Ineeded to know looking for as complete a burn as possible in my 21" barrel

Try working up to about 31Gr's. of AR-Comp, you should get a complete burn and slightly lower pressures while still running in excess of 3200fps. If H-335 is all you have that should still work fine. Good Luck

Well I wanted to post back results.
This is my first Savage build McGowen 6BR 1-12 twist bull contour 21" long. I wanted to run the 60 to 80 grain weight bullets. I had tried Varget with the 65's no luck.

I gave the H335 a try today I worked up to the 33.5 grain charge.
I think it will work for me.
I havent been target shooting very long a friend of mine sent me in the direction of this site almost a year ago.

Im not familiar with AR-Comp???

 

[Chuckhunter]

Certainly looks like the right place to start. AR-Comp is a relatively new powder produced in Sweden for Alliant Powder company. It is a fine granule extruded powder that is not temp. sensitive and burns very clean. I had good luck with it in my Dasher. Hope the new rig shoots as well or better than your last build.
