Quickload help for 300 WSM & 125 Nosler Ballistic tip

[57chevy]

Hey everyone new member but have been following the forum for a while. Just wondering if anyone could run some quickload data for me. I'am looking for a powder for the combo below. I'am currently playing with Vihtavuori N550 powder and worked up from Noslers most accurate load of 66.0 grains which is also the starting load to 69.6 There max is 70.0 grains I plan on creeping up a little more but was curious what powders quickload would come up with.

300 WSM
Norma case
WLRM primer
125 nosler ballistic tip

Rifle was built for fun at the range and hunting.

Montana action
Shilen 26" barrel 1:10 twist
HS precision stock
Scope zeiss conquest 4.5x14

Rifle will shoot one whole groups at 100 yards using

180 nosler accubond
Norma case
Vihtavuori N550 59.5
WLRM primer
.030 off the lands

I use the rifle for deer hunting and woodchuck hunting and wanted to
find a load with the 125 bt.

WORK UP TO THESE LOADS!

You are on the right track with N550, QuickLOAD shows it to be one of the best powders for the 300 WSM and 125's. Max if you are jumping bullets appears to be about 74 grains with a COAL of 2.880" and a 102.7% case fill ratio and 99.7% propellant burnt on a 26" bbl.

Winchester 760 also looks to be a good one, it shows 75 grains to be a max load with 100.7% case fill ratio and 98.3% probellant burnt on a 26" bbl.

Hope that get's you started.

Thanks for the help Erik going to keep working up slow with the N550. I think I will give the Winchester 760 a shot also. I can’t believe I haven’t pulled the trigger on that quickload program yet.
