optimum powder for a short barrel 30-06?


Reloader

Recommended Posts

I have a Ruger M77 UL .30-06 with a 16 1/2 inch barrel.

I am looking for a powder that will give me optimum muzzle velocity from that barrel length for a 150 gr. bonded core spitzer.

If you have a suggestion on powder, pls post the powder and manual or web site the load is listed on and I will try to find the load data there. (If I can't find it I will PM you for the PUBLISHED load data. I am not looking for loads worked up on unpublished powders.)

I am currently using Alliant 2400 on the dual reasoning that:

1. It is a fast pistol powder and therefore matched to a shorter barrel.

2. I only need half the charge as compared to Alliant Reloader 15 but only lose 5-600 fps or so according to the full length barrel results listed in my manual. (that makes it cheaper at least for plinking grin.gif)

Alliant publishes the Muzzle velocity for the max load of Alliant 2400 as 2300fps in a standard test barrel...anyone have an idea what velocity I should be getting from my 16 1/2 inch barrel?

Hey James,

I had great success with IMR 4895 in a 18.5" barrel in the 30-06. If I remember correctly, the Hodgdon annual magazine has load data for the Encore handgun in 30-06. It has a 15" barrel so the data would be comparable to your 16.5" Woogah.

I would stay away from the very fast powders. I like a powder charge that fills at least 80% of the case. You can run into detonation and burn problems if you have too much empty space.

You should be getting 2600-2700 fps with a 30-06 using 150 gr bullets and normal powder in your carbine.

I could not find the 15" Encore data on line. I think its in the annual magazine though. I may be mistaken, it has happened before (just once). You should be within 150 fps of standard rifle (22" barrel) loads when you use the medium burning powders like 4895, 4320, N140, AA-2495, Varget, etc. I would stay away from ball powders though. They are the hardest to ignite.

IMR 4350 ain't bad either ...

In a standard rifle, I would agree, but in a 16" carbine, there are bette choices. It's just a little too slow for that barrel length. It will produce a rather impressive muzzle flash when it gets dark though.
