[QUOTE="Sand Man, post: 2014944, member: 65904"] Backstory: A little over a year ago I wanted a magnum caliber for an elk hunt I was going on in Colorado. After some research and Berger making the 195gr in .284 I landed on the 28 Nosler. I didn't have enough time to build a custom gun, so I ran across a Christensen Mesa Long Range in 28 Nosler. During load development the fastest we could push the 195s without pressure issues was 2850 if my memory is correct. I just wasn't happy with this. By all my research, I should have been able to push the 195s at or over 3000fps. I felt like I was handicapping myself with the Christensen, so this past off season I sold the gun and started purchasing parts for a custom build. I decided to go with a Zermatt formally Bighorn action, Bartlein #3 1-8 twist wave fluted and finished at 26", Iota Kremlin stock since McMillian and Manners had long lead times, H-S precision bottom metal, Timney Calvin Elite trigger, and Harrell muzzle brake. I had Tony from ZG Customs here in Texas chamber the barrel, bed the stock, and cerakote in olive drab to match my stock. I went with a March-F 3-24X42 FFP scope with mil reticle.

Since there was no published data on the powder I could find avaliable and the 195gr Bergers we started conservative on the initial charge and worked our way up. Here are the 1st 5 shots out of the gun to foul it, break in, and zero scope: [IMG]https://texashuntingforum.com/forum/pics/userpics/2020/11/full-692-262853-20200823_130728.jpg[/IMG] Better than any group I ever got with the Christensen, so I was happy with the rifle from the 1st trigger pull.

I never saw pressure signs at 79.0 grains, so I decided to start there with another ladder test. Here are the results of the 2nd ladder test: [IMG]https://texashuntingforum.com/forum/pics/userpics/2020/11/full-692-262860-20200905_121626.jpg[/IMG] [IMG]https://texashuntingforum.com/forum/pics/userpics/2020/11/full-692-262861-20200905_121800.jpg[/IMG] At 85.0gr of powder and 3129fps, I was just starting to see signs of pressure.
