Load Data for 6mm PPC

If you put vertical into your load instead of drilling holes youll be in the bottom third by the posting of the second target in a ppc match. In other words any vertical at all will not work when the top 20 are shooting teen aggs
 
And that’s why I’m a duffer. I can’t stay in tune with zero vertical. I always have one blow up.

Up the powder charge til it goes away then watch the temp. Go down in 2 steps and shoot all 3 charges on the sighter so if you get caught youll have a lighter charge in the box to fall back on. 7-8 of each backup load should tell the tale
 
In light of what has been said here I believe I have the load I am using is pretty close to perfect. There might be some tweaking to be done
and there may be another node to be found, but I like what I am seeing so far. Five shot groups at 100 yards.

2 suggestions;

#1 get some round aiming points. Order or print off some bench rest targets and print out pages of the circles. Those lines are so fat they're making your groups bigger. And aiming at lines can't really give you consistency any road.

#2 stop shooting out your crosshairs...... you NEVER want your bullets hitting your aimpoint.

Like this I hope.

So do you set your scope to shoot high, low, left or right of your aim point? And, how far from it?

99% of the time I set the crosshairs at 6:00 splitting the mothball with the vertical crosshair. For me this makes a switchy wind easier to follow...... and I'm all about "maintaining mental images" because I'm kinda' mental. The oldest sight picture in the book is the "Pumpkin On A Post" scenario which I have grown up with on everything from pistols to deer rifles.

I guess I'm just programmed to "Hold Low" so that's what I do. One less thing to think about.

I know a lot of BR guys who side-hold and it's never worked for me because sooner than later I leak one out in the wind and hit my crosshair...... altho I have at times clicked some side on to bracket the mothball in the corner, like lay a hair on one side as well as the bottom. I've done this when mirage has the ball bouncing because I can see the "snap-back" better.....

That's the old way. Just use a tuner...seriously! This is exactly how tuners are best utilized. No carrying multiple loads to the line and no reason to leave any amount of tune on the table. If conditions allow, tune it to the hilt, right at the bench.
 
If your goal is shooting with the best in conditions that are fairly calm, your looking for a tune that would be three shot groups over close to a grain all in low low ones (really should see At least one zero) and none of this sine wave stuff. Confirm later with at least 4 shot groups. That’s why many of the best don’t use tuners or at least seldom turn them.
 
Powder charge weight is just one component of a ppc load
More importantly is the seating depth. If you don’t have it no amount of powder or tuner adjusting is gonna help
The seating depth may need changed for a right to left or vs Vera’s wind push. You definitely see this at 200. Your gun just drills them in a right to left but falls apart in a left to right if your seating depth isn’t right

Tim, I haven't chased to lands in a barrel in a long time. Slow, progressive wear is hardly noticeable in terms of tuner setting. Temp changes mask any small difference in tuner setting over time.

As for how often I move the tuner, it's not often nor far. If you see me twisting more than a mark or two over the course of a day, something is wrong. But, temp changes are by far the biggest factor in condition related changes in tune. I'm not one who believes that there is some magical window where temps stop affecting the the chemical reaction that takes place during smokeless powder combustion. There are areas where the gun is tuned that are wider than others in terms of harmonics, though, where tune changes less with equal temperature change. Still, the barrel never stops moving and temp never stops changing the way the powder reacts to those changes, imho.

I’m not talking about chasing lands. Just being in the right place to start with.
 
How would this target score in a competitive match? I am new to this and have only shot this rifle four times. Really have no idea what is good or bad.

That series of groups would agg in the .190x MOA. Which is a good agg but probably not good enough to win at a national level match.
