Painless load development (mine)

That's a 93 shot group!?

Yes that is a 93 shot group at 100 yards.

Ho-ree chit, that's fantastic! What are the rifle and cartridge specs?

 

[Q_Sertorius]

Terrible shooting!










Just kidding…

Seriously though, adjust your scope half an inch to the left.

First time reloading.

Read this thread before and resolved to follow it because why make life hard?

Shot 9 shots yesterday to find where I hit pressure because it’s my first time doing this and was being cautious. Loaded up at what I thought was a good place below max and came back today to zero.

Did two sighters, followed by 93 more shots at 100 yards. Can vouch that this method works. Now I’ve got 104 bullets down the barrel and won’t clean it for its entire life.

Thanks Form for putting the knowledge out there.

Why didn’t you zero the gun before you wasted all that ammo?

Didn't want to shoot out his aim point with such an excellent group... lol #protip

Ding, ding we have a winner!

Ok I got a lot of questions over message, so hoping to answer all here:

1. The gun is a 6mmBR shooting 105s with 30.2gr Varget. Fed from grey ops magazines, I haven’t experienced failures or cycling issues that used to plague BR and its derivatives in the past. Where I live, the BR has enough velocity to kill things far past where I could get shots at game, so I didn’t ever see the need to go “faster”. It would all be theoretically and not practically beneficial.

Being a BR, this is partly why it was so easy to load for and so accurate. It’s my first time attempting reloading ever, so I did it with a forgiving gun that I knew wouldn’t be fussy. These literally were the first 104 shots I have ever reloaded. Did 100 in one sitting yesterday in preparation for today, elected to not shoot the last 5 because I was already over 100 if you considered the 9 pressure loads yesterday morning and, looking at the target, it really didn’t seem like I was going to prove anything new that wasn’t already there.

2. Shooting 104 total shots - why? Well it was the first shots down the barrel and I wanted to get some fouling/track if it sped up as rounds went through before it stabilized.

3. It was my first time reloading ever, so I wanted a very strong starting, statistically very valid, sample as to what my gun was doing from a SD/ES and velocity perspective. Since I wanted to foul with gun with 100ish shots anyway, this was the perfect convergence of two goals.

4. Will I do this again? Probably not. It was a great experiment since I wanted to foul the barrel anyway. I don’t plan on changing anything in this till the barrel just straight dies.

Hope that helps. I tried really hard at being sloppy with trigger presses just to see what I could get away with, and everything kept going through the same hole. There are some absolutely sloppy shots in there, but I won’t claim the gun will be more accurate because the paper doesn’t lie.

What action was this rifle built on?

Gotcha, better off being high and wide than on the money

You might want to weight sort your brass and primers, maybe even play with seating depth, to really tighten up those groups. Also you should clean it roughly every 100 rounds so you feel better.

All kidding aside, excellent work!

That’s what I would do

Custom 7saum rem 700 from lri with 22” kp barrel with enticer L can.

60.5gr H4831sc
168 Berger
Coal 2.32 (about .020-.030 off the lands)


The Berger book called for max of 60.3. I’ve shot that with no pressure. So I bumped it a little and am not too happy with the group or the sd and es. Again no pressure. But I did manage to avg over 2900fps. I’m wondering if I slow it down some will the group tighten? I do use this rifle to hunt but it’s also my long range gun.

Good grief dude! That is a phenomenal group!

Dropping the charge can improve dispersion, but it usually takes a fairly significant drop and a sacrifice in velocity. I'd recommend dropping 1.5gr and shooting a test group. If it isn't acceptable, swap bullet or powder.
