Yes I know there are better for this that and the other blah blah blah, I wanted to try this so I am
I started with working up a load for my Savage 12 LRPV .223 I have never used Ramshot TAC so it was time to do some load work.
I am using 75gr Hornady BTHP match, TAC powder, New Lapua Brass. .015 off the lands
I neck sized the brass first, looks like the die needs a nip tuck.
Here are 100 neck sized virgin brass
Primed and ready to dump some powder
Now the fun starts, Using the RCBS Charge Master
Look here for more info on that > Weighing In, Scale test.
Powder dumped and ready to go. I will seat bullets at the range to save on components
Loaded 10 of each at
More info here > Ladder testing at 1k- Detailed article and video - Page 3 - Long Range Hunting Online Magazine
It was cold and had a bit of an on and off again wind.
Load testing was done at 300 yards
I had other rounds for sighters, and a 24x24 inch steel set of for that
Shot the ladder test from min to max
Driving down to look at the target after each shot and recording it on a note pad, I could not see the hits.
Loads 4-8 looked promising so I shot each of those as a 3 shot group
All of these numbers are Elevation measurements only. The wind was off and on, So I did not worry about that.
At this point loads 7-8 were looking promising, So I drove down to paint a few more dots to aim at.
Set up and put 2 sighters from load 7 & 8 into the steel
At this point I had 4 rounds left from row 7 & 8 left so I let them fly!
Measurements done on elevation spread only
Looks like 7- 23.2 is the winner, here is the over all group size center to center
Here is the total round count fired, the rest will be dumped and re measured and loaded at 23.2gr
For those of you wondering about pressures
24.1 - 23.2 - 21.4
Here are the "extra" ones, dumped the powder back in the charge master and loaded to 23.2gr
