28 Nosler Sanity Check Please

[Mr6.5]

Tomorrow I am going to try the 175gr Maker T-Rexx copper bullet in my 28 Nosler. There is no load data for this anywhere. I used Hammer and Barnes data along with QL data and came up with N570 at a starting load of 74gr. I loaded a string from 74 to 82 in one grain increments. Anyone see this as an issue? My OACL is 3.4550.

Mono bullets are recommended to be seated off the lands at .050".
How was your results on your tests?

Hey Mark, Today went very well. I worked from 74 to 82 grains letting the rifle cool in the truck AC between strings. I found mild signs of pressure at 82grs of N570 (tight bolt lift), backed off and shot a group with the 81gr loads, 1/2 MOA! As this is a deer rifle that is perfect and will be the load I hunt with this coming season.

Wow, 3300 plus fps with a 175 mono. That is some insane speed. Half an inch @ 100 is a good load.
How far off the lands are you seating those monos? Any pressure signs on the head of the brass if I may ask?

I am .030 off the lands, ZERO pressure signs on the head or anywhere else at 81grs, the primers even look great. I was impressed with these bullets and how easy they were to work. If I had time I am positive I could squeeze the group down in the 2s or 3s but as it is a hunting rifle no need to burn powder. barrel, and bullets.

You know the only complaint I have about the 28 Nosler is the recoil, I have a 26 and 30 Nosler and neither recoil like this 28. All have brakes and all in are Bell and Carlson stocks, no idea why the 28 has more recoil, but it does not bad just noticeable. I shot it without the brake once, NO THANK YOU.
