First results with new 12 FV .223

[hamiltonkiler]

Here is a summary of my most recent results with N140 powder with Sierra 69 SMKs and TMKs and Sierra 77 SMKs and TMKs.



It shows I was a bit out of practice but the average results are surprisingly similar for all the bullets and weights.
The Averages, Medians and Standard Deviations are a bit larger than I would like, but it shows that I had not yet managed to maintain consistency after more than a month layoff.

Great shooting! Any pictures of the gun you would like to share?

Not much to see.

Just a 12 FV with an Oryx stock.
But there is a temperature strip on the barrel, a Sightron 36X set in Burris Signature Zee Rings.
the picture also shows my standard bench set up.
The rifle is mounted on a Sinclair Gen-3 F-Class bipod and the rear rest is a Protektor bag with a carry handle.
There is a Barrelcool fan in the breach and a Sinclair elbow pad to the far side of the rear bag.

I recently changed to a Leupold 45X scope for this rifle.
I got it at a bargain price from a range buddy who is moving and was reducing the amount of stuff he had to move.
The latest N140 loads were shot with the new Leupold 45X.
Even an increase in magnification can't overcome being out of practice.

Dang what a beauty!

From the temperatures at the time the loads were shot in the list in post #70, you can see that the 77 TMK loads were shot first during each of the morning sessions. because the temperature was the coldest.
That may account for why the 77 TMK average is the worst of the lot.
With the lack of practice time, I suspect it took me longer to get my technique together.
Normally, my concentration is the best shooting the first load of the day, but for the first two sessions that seemed to be just the opposite.
For the last session, the 77 TMK average was the best of the day and the second best of all the averages for all three days.
The 77 TMK load was also the first load shot on the third day.
Maybe the practice did do some good, after all.

This thread was a great read. Thank you for your attention to detail and documentation.
With luck I will have my new to me 12 FV (223) at the range tomorrow. Added a 15 yo Bushnell elite 3x9 .
My load will be SMK 69'S on Varget. 24.4, 24.6 and 24.8 grains when loaded just under the Ogive yielded COAL of 2.298, give or take.
Fingers crossed.

Thanks for the compliment. I didn't think anyone was still reading this old thread.

There is another set of results documenting the results when I changed the factory stock to the Oryx Chassis that may also help.

The (sometimes) great thing about the internet is once something is said, it's out there forever.
I like the fact you made mention of Quickload. Aside from my good buddy who owns it, no one else seems to have ever heard of it.

This has been a thread of interest since I found it last summer, I unfortunately lost all the information with a computer crash .

Having just found everything again I just wanted to say thank you .
