Thoughts

[Butte Sink]

Hello All,

I wanted to show a load that I put together over the weekend and wanted to see if I could get your thoughts on what you see and which may look somewhat promising to you

I was leaning toward trying 66.0 and 67.0

Anyway let me hear what you think

Thanks

Here is some of this loads background

7mm Rem Mag
27.250 Hart 1-9 twist
N560 Powder
GM 215 Primer
Nosler 160 AB
ADG Brass-- Trim / 2.4485
CBTO-- 2.2245 /.020
COAL-- 3.253

Starting-
64.7 - 67.4
10 / .30 increments

I'd probably go with the 65.6 gr load. Looks like it is the most stable and just 100 fps off the 67 gr load.

your chart shows nosler brass you say ADG what did you use? I like the 65.5 load

No target data?

Chrono data, alone, can be very intriguing. And so can accuracy data by itself. But it's when both those things start whispering the same story that you know you're onto something.

A quick-and-dirty with QuickLoad suggests you probably have some pressure to play with. Some critical information is missing (such as the case capacity of the brass you're using, and confirmation on that 1.410 bullet length) which is why you need to take it with a very large grain of salt... but it might be interesting to see what you get as you transition into a compressed load, which often exhibits more uniform ignition.

Yes, from what you've loaded it looks like you've got a couple spots to explore. But I'd say getting some holes in paper is the biggest priority...

Thanks everyone for getting back
Jager I did adjusted the bullet length on my QL to the average of 1.3825 and will be doing a H20 for CWM and get that data inputted to see the changes, Did have to play with the burn rate to adjust the velo.
As far as target data, I really didn't focus on "good" shots and was kind of going off of Satterlee 's load development but looking over all 3 shot groups
65.6-- .75 MOA with horizontal separation
65.9-- .375 MOA with vertical separation
66.2-- 2.0 MOA with vertical separation "Straight line up"!!
67.4-- .50 MOA with vertical separation

Again I didn't focus on good shooting but I'll play with a few of these and see what turns up

Thanks all!!
