Anyone load for precision long range shooting?

I built my rifle last year and have spent the time between working up loads that my rifle likes and learning about getting the lowest standard deviations and extreme spread I can.
that has not been as easy as I thought it would.
takes a lot of time on the range and several steps on preparing brass.
The newest thing I've started is using a bushing .003" less that the spent brass and then running a mandrel you uniform the neck. That is giving me around 25-30lbs of seating pressure. All the brass were turned to uniform the necks.
Last time to the range I had 4.1 S/D with an ES of 11.
still wanting to get that lower if possible.
This is for 6.5cm, FYI and that last group was avg 2773fps and grouped at .306" 5 shots
Just curious if anyone else is doing anything similar?

I don’t know how far down the rabbit hole I’m going to end up going but I have been testing loads for my 6.5cm. I haven’t gone nearly as deep into it as you have. I’ve got 5 shot groups down to .5” and SD around 10.
I’m shooting my rifle at 600yds this Sunday and after that I’ll be able to go shoot at 600 whenever I want. I don’t really plan on doing it other than just to go shoot every once in a while, but who knows what I might end up doing with it.

I've yet to qualify for the 600yd range at my club. That is the goal. If I shoot in a competition I will be qualified. There is a competition in a couple of weeks.
I may go over to another range that is 1-1.5hrs away that reaches out to 1500. Would love to try that.

Well, you are shooting .306 5 shot groups @ what range? 100? 400? 600? If at 100, great, but wind will be your nemesis when you go to 4-600. Elevation can be conquered quickly, windage, no so quick.
I shoot .308 with 175 SMK and stay around 1.3" @ 400. 2" groups at 500 is my present goal, but again, wind giving me trouble. It's still a learning process for me. Stock rifle Rem 700 5-R with Vortec Viper 6-20X56. Hand loading with 41.9 gr. 4064 @ 2.80 Laupa Brass BR-2 primers. Heat is also starting to factor in with powder. Good luck with your trials.

My specific load is 42.5gr of staball 6.5.
Loaded to 2.9135" (Very long, I know)
.306 is at 100yds. Wind is what I am wanting to figure out. Well, that and everything else.
Rifle is one I built. Bighorn Origin action
Criterion 26" barrel
Magpul stock
Vortex Razor 4.5-27x56
Triggertech special trigger set to 1.25lbs
I have a Ruger American Predator in .308 that my loads are really good but it's shooting barely under 1".
have that one shooting with 2 something s/d

That's better than 99.9999% of the population.
And 99.99% of gun owners.

Well, when the gun is sitting on a bipod and rear bag, it isn't that hard.
With that set up I can easily shoot that. The bigger issue is the ammo.
ammo can mean .2" to 2" at 100yds.

Do any of yall use a meplat uninformer? Worth it?
Posted on 7/16/20 at 6:53 pm to Duckhammer_77
I don't, but thats not saying it's not worth it. I'm not that far into this money pit yet. haha

Looking hard at a 28 Nosler once I get the feel for reloading. I think I’ll be more concerned with hitting double lung than standard deviation, but the principles are the same. Cleared out a couple projects in the last month or so and should get down to business here soon.

Yeah if my math is right, that means 5-.263 diameter bullets went into a .306 diameter hole, which only leaves 43 thousandths wobble room, one hole. May be common in competition shooting but from the loading and shooting I’ve done for hobby and hunting, that’s not easy to accomplish.

Group sizes are measured from the center of the bullet.

You already do more than most. I dont turn necks.
I havent started loading for my 6.5 creed yet. I still have factory prime ammo left, but will soon.
I will say when I got to shoot matches, my loads werent anywhere close to your. Maybe like 3/4 moa-1 moa. Fitness/fundamentals was way more important than chasing group sizes.
But if thats your thing. You might try measuring run out, weight sorting brass and bullets, trimming meplats, pointing bullets, etc.
ETA: Now that your groups are small, start shooting dot drills. Mix up positions(sit, kneel, stand), build a vtac barricade, etc.

Have not trimmed the meplat at this point but it is something that I’ve thought about when looking at the various COAL based on differences in the meplat.
I’m sorting brass to 1gr and also sorting bullet length to ogive
My brass is Lapua SRP.
So, measuring group size, take the widest part and subtract the diameter of the bullet.
ETA, I have also never measured concentricity. I may at some point but not yet. I’m using LE Wilson seating due with VLD stem (my bullets are Berger 140 VLD hunting)

Can I send you my brass/bullets/powder?
To be honest i had a concentricity guage when I was loading 260 with redding type s dies. I measured a couple hundred and then sold the guage. Lol.
Pointing might help, but that probably would be more noticeable at long range.
Ohhhhh, are you annealing your brass yet?

Yeah have a bench source annealer. Not ready to throw out the cash for an Amp yet.
This stuff is fascinating to me. So many variables.
Once I found my powder node I then started playing with bullet seating using Berger’s method:

Load 24 rounds at the following CBTO if you are a target competition shooter who does not worry about jamming a bullet:
.010 into (touching) the lands (jam) 6 rounds
.040 off the lands (jump) 6 rounds
.080 off the lands (jump) 6 rounds
.120 off the lands (jump) 6 rounds

CT07, help me understand, does one half the bullet hole not count in measuring? If he shot .306” does that mean that it was actually .612”? If two guys are at the range shooting, let’s say the 6.5 Creedmoor which I’m pretty sure is a .263” diameter bullet. One of them shots 1 round into a paper target at 100 yds, the other one holds a dial caliper as he watches his friend shoot. They walk to the target, lo and behold, it has 1 hole in it. The one with the dial caliper measures the hole. Based on it being a .263 bullet, would his measurement be .263-.264 or would he say it measures .1315”? Meaning he measured from the center of the hole. If multiple shots are fired, does he not measure outside to outside?
