Ramshot Powder

Funny you should post this... I just emailed Ramshot yesterday as I would like to try some Hunter in my 6.5x47 Lapua. This is what they had to say.
"Modern spherical/ball powders are reasonably stable compared to the original 1950-60’s products.
However it will always be affected by temperature.
We test at -40F and +125F and the deviations at these extreme levels are usually between 3% to 5%.
Most users/hunters will not notice any significant difference at the typical practical hunting temp’s.
It also depends on the caliber and the performance level your were loading at."
I have read where their Magnum powder was very temp stable, I believe it was a test that Barnes bullets did. I think Hunter will be a awesome powder for the 6.5x47.

The load I am using for my 6.5 Creedmoor is:
44 gr. Ramshot Hunter powder
140 Amax
-.005 off the lands
CCI large rifle primers
2798 fps
groups are around .250 - .375 @100 yards
This load shows on signs of over pressure in my rifle.
Will work with this load hope to get better.
Oh did say any thing about this power meters so fine in my Redding powder thrower.
!!!!!!!PLEASE USE CAUTION!!!!
(REMEMBER THIS IS WITH MY SETUP)

I was just at the range shooting two calibers with Hunter powder. It was 35 degrees. I am at a loss on this one. My 270 loads were pretty consistent. My 6mmAI groups more than doubled in size with the same loads. The barrel did not get over heated. You would think that the temperature would effect both calibers. I do not know why the group sizes are so drastically different. Every round was weighed out on a good powder scale.
@Sidwinder,
What it basically boils down to is Accuracy Nodes. Different setups will have different "Sized" Accuracy Nodes. Both pressure and temperature will affect the "width" of an accuracy node, other factors will weigh in such as rifle, powder, bullet, seating depth ect.
How close to the "center" of an accuracy node you are will have an effect on how your particular setup does in differing weather conditions. Also, the "width" of that accuracy node will determine how sensitive your setup is to ambient conditions. If you have not already, perhaps do a lookup on OCW. Some pretty decent info on how to choose an "Accuracy Node" for best overall performance. I know there are a few really high profile peeps here, so maybe 1 or 2 of them will chime in and add some clarity to what I am trying to say.
Good shooting,
Gary
