Sunday morning I finally found a load for this bullet. I got a 5 shot group in the .3's with ES of 7fps.
That evening I loaded 6 more rounds, put my data in Ballistics AE and set up on the 375 yard steel plate.
Shot once, took 2 clicks of elevation out and then shot 2 with each touching the...
I am learning that this is not an exact science.
I measured 6 cases from a friends rifle and remeasured 5 of the cases I measured from my rifle and came up with 73+ for both.
What I am sure of us that Nosler's load data for this powder and bullet is way off and dangerous.
This pressure...
Got Ya.
Per the QL above I should get near 3050 which is only 5 off of the max Nosler lists for this powder anyway, I'm great with that if they will cluster into a tight little group.
Thanks for the help

I run a machine shop so that makes perfect sense.
But if factory ammo or resized ammo fits the chamber the only way to get this extra capacity is with a good deal of case stretch it seems.

Y'all have me intrigued.
If the chamber is cut with proper headspace to handle factory loaded cartridges and the loaded loaded cartridge size is controlled by quality resizing dies where does this extra case capacity come from?
Again, not doubting your knowledge but extremely intrigued...
Now you have me curious. I have 8 cases here fired from a friends rifle built by a different builder. I will check capacity on them tomorrow.

Hate to say but I doubted my results enough to try again the next day which was very overcast and results were consistent.
Hard bolt lift, great velocity, and 3 shot group in the .3's.....

Excellent info. As asked by PM I would appreciate some info on what combo you put together to make this bullet shoot in your AI

My chrono is a ProChrono Digital as seen here http://www.competitionelectronics.com/p ... o-digital/. It is not expensive but it has served me well for several years. Shooting was done mid-day with good sun light.
Yes there were ejector swipes on the case heads.

Does anyone have experience loading this round using Viht N-165?
I then went to Viht N-165. I am seeing some signs that I can get the accuracy I need out of this but I am extremely surprised at how far my velocities and pressures are off from Nosler load data. I hit hard bolt lift @ 62g which...
