Load Dev spread sheet

[georgelza]

Hi all

Starting to prep to do load development.
Looking at shooting 8-10 sets, .2 jump between each, 4 shots per weight.
For N565 I can start at 67.4 -> 74.4
Does anyone have a pre build spread sheet they willing to share where I can load the data into that will show the graph to find probable nodes... areas to further investigate?

for now, going to do 2 load developments,
#1 225 Hornady ELDM,
#2 230gr Hornady A-Tip,

on top of N565 with Federal Magnum 215 Large Rifle Primer in ADG brass (300 prc)

Curious... why would i not look at N570 ? I'm being nudged towards N565

Rifle is a HOWA 1500 with a 24" barrel

Never mind, found the 6.5 guys reloading spreadsheet, it seems everyone is pointing at this.
Happy to be pointed to a 2nd option.

Here is what I have for my 300nm with 230 A-Tips
Brass Norma
Primer 215m
Powder N568 86.2
I set them 20 off the lands
AVR FPS 2945
SD=6.8 on 5 shot group

Just as reference here is the 230 Berger Hy's
Brass Norma
Primer 215m
Powder N568 86.2 (same as the A-Tip's, it also was the same zero my scope for both)
I set these 10 of the lands and the groups did tighten up vs 20 off.
AVG FPS 2937
SD 5.9 % shot group

Hope this helps
