Good Results With IMR4007ssc

I decided to work with IMR4007ssc in my 30-06 Marlin XL7 using my favorite bullet when hunting whitetail deer and hogs, the 165gr HPBT Sierra G/K
My load chain was:
165gr HPBT Sierra G/K
IMR4007ssc
Winchester Brass
Fed 210 Match primer
OAL 3.185"
Results:
Velocity - 2907fps average
Extreme spread - 13
Deviation - 5
Group size for three shots -
Target three shot group
[
Increased the charge by 3/10 of a grain and average was 2938fps five shot group.
Target five shot group with 3/10gr increase.

I liked how this turned out, will use IMR4007ssc with my 06 some more.

You never cease to amaze me by your limited experience of things because you get most of what you know from reading instead of doing. The top load I used is a near max load from Q/L I am not over book. I am not
over pressure for this rifle and chamber, and extraction is easy and no other pressure signs. This 06 has always exceeded the velocities of my Ruger 22 inch barrel by at least 80fps on the average. Now let me let you go back to reading, which you are good at. I used 62500psi Q/L data not 66,000psi

Alcohol, Tobacco, Firearms and Explosives.... now who's bringing the hot wings? :jester:
No, they are only 100yds I put the wrong yardage number in the program when measuring the group
Paul, I appreciate you taking the time to send me what you work up. Mike
Paul, I deleted the real dangerous load list that I sent you on PM in this public post and here is what I came up with when I did it and my barrel is really fast. Also, I will be checking out my chronograph by bring my other one and comparing. Lord I hope it is not off, but I will see.

Isn't that why you fight so you can kiss and make up?
Just be glad you're shooting Mike.
I don't feel good enough to do that, but I'm getting there.
I need to get quick load one of these days, it seems like a really cool program.

I have followed this thread and look forward to your results. I've read here and elsewhere many times that quickload was off base. Real world results are what counts in my book.

I could almost justify one of those Tennmike. There's at least one load I would love to know about. Actually, I COULD justify it, but I don't have the change now. Not this time of year. But it is interesting.
Son that's somebody with nothing to do with his time but keep me in trouble with mom.

165gr Sierra HPBT
56.0grs IMR4007ssc
59,189psi
2848fps he said my chrony is off on the average of 59fps (will check this again at the range and compare to my back up crony)
I can live with this load if it is 2848fps and my back up verifies Roberts chrony findings.
