Need powder suggestions for a 16" pistol port barrel.

[Mike Bell]

Ok fellas Im getting my order into Hoser for brass and need to pick up some powder this week so i can finally shoot this thing.

I got an 16" barrel with TP555 adjustable gas block in the pistol location.

I got a box of 150gr. Hornady interlocks, half a box of 165 gr. Hornady soft points and one box of Barnes 130 TTSX. As you can tell these are my hunting bullets so for right now I'll be working up a hunting load which will be super sonic. This will at least get me shooting this puppy

I know my local shop as some H110 ( i saw it last week), but not sure what all else he has. Im gonna stop by and see what all he carries or can get pretty easy for me.

So I really need a list of super sonic 130-165 gr bullet powders. Or a reloading manual that has whisper loads please......

Any primers to stay away from? I have a 5 or 6 packs of Winchesters but thought about ordering a brick when I find some bulk bullets.

Sierra Whisper Reloading Manual

[martineta]

One evening I did a google on reloading 300 whisper. I had loads of hits. I cut and pasted the relevent pages, probably 15 pages or so and used my son's 3 hole paper punch for school, put them in a three ring binder and made my own reloading manual. I use H110 for my super sonic 125 grain and 150 grain hunting loads and N110 for subsonic loads. I shoot a 26 inch SSK encore barrel. 18.5 grains H110 for the 125 nosler BT and 9.2 grains N110 for subsonics and 225 Outlaw state bullets.

Some on this forum don't like H110 but it is one of JD Jones' favorites. When I ordered my barrel I mentioned that some on this forum dont like it and he just laughed. I bought a pound and am very pleased. Works like magic in my 22 hornet also!

I kill deer with both the supersonic 125-150 Nosler BT and the Subs using outlaw state bullets. I hope someone talks to the 2400 powder. It is one that I want to try.

yea I started saving this stuff already but I was hoping for more published data. I actually printed the Sierra stuff months ago before I even built the gun. And I would really like see these side by side with the Blackout loads.
