Barnes Bullets
 

Hello all, I glad to see there is a 300 whisper forum finally!
I have a question on reloading of the Barnes Triple Shock 150 grain bullets for the whisper. I have a encore barrell 18 inches long, the primary use is deer hunting, I have done some nice loads with the data out there at reloaders nest, but I would love to try the triple shocks.
I want to know if any members have tried these rounds for hunting, and if there is anyone with load data on this bullet to get me at a starting point?
I was asking this so that I did not have to go through and set up the bullets off the lands (.50 to .100)
Well any input would greatly be appreciated.

Barnes Bullets
 

i'm going to be doing some shooting with the barns triple shock I will let you know what I think when I get to it. it might take some time I have been working on other stuff lately I have a freind that has used them I will talk to him and see what he says.

I have some rounds reloaded, they start at 15 grains of H110 yo 19.5 grains of H110, I will get to the range this coming weekend to try em out.
They are seated .060 from the lands.

Well everyone its been awhile but I finally got around to testing the new Barnes Triple shocks in a Encore single shot rifle with a 18 inch barrel.
Here are some things I noticed DO NOT load more than 17.0 grains of H110 in the cases. At 17.5 grains of powder there is a noticeable primer over-pressuring, 50% of the primers actually were forced from the case itself.

Here is the actual loading data: use at your own risk,
Barnes 150 grain Triple Shock
17 Grains H110
Bullet at .055-. 060 off lands
Group was .397 @100 yards

The grouping was very consistent from 15.7- 17.0 grains of powder, there was a noticeable elevation in groups size below or above this number.
All testing was done at sea level.
