Painless load development (mine)

[Gstew1930]

14 shots out of a brand new rifle. Painless. 4 to zero & check pressure. 10 to verify. Load is done

So @Carl Ross was correct. The Harrell’s powder dispenser is legit.

Dumped 50 charges in just over 3 minutes. That would normally take 45’ish minutes with the electronic dispenser.

5 throws in a row with H4350- not trying to be consistent at all; just lift, drop.



Here’s the group-



That’ll do.

Did you check the charges to see how consistent it threw h4350?

I bought the harrells measure also because of this thread.

It meters varget very well, I checked the 1st 10 charges and it was within .1 (measured on a lymen pocket scale). Threw 50 and haven't looked back.

H4350 seemed to occasionally throw .5 under or .5 over. Most of them averaged about .2 to .3 off. I didn't rethrow or trickle any of them, mostly just curious to see where it would end up. Loaded 100 rounds in short order. Slow twist .243

How big of a spread do you think would be acceptable for a 450ish yard gun on powder charge? Within a gr?

Sigh. The picture didn’t attach. It is in the post now. .2 grain variance with H4350 across five dumps.

Depends on the gun. The load above had at a minimum .2 grains variance- and yet shot a .67 MOA- 9 shot group, and the ES/SD was just fine. That load is a near 800 yard load for animals.

Awesome.

My initial 20 shots for the painless method had a .5 grains variance and 1.1" for the first 10 at 100 and 5" vertical spread and 7" horizontal spread at 574 for the next 10 (little breezy).

Thanks for all the information.
It was mostly because of this thread that I finally started reloading.

Yeah, that load is done.

You are welcome.

That insinuates that you’re shooting the aero match at critters?

I would. But no. TMK’s.

What dinosaur dispenser are you using that takes nearly a minute per charge??

My setup is a harrels that dumps into my cup on a FX120i, usually set up to throw ~.1 under my target and I trickle the rest. Maybe 10% will dump my target weight with H4350, and maybe 5% are over my acceptable variance. +/- .2 with H4350 is mostly what I see, you will get the occasional +.35 or -.35, so I still like to weigh them all because it gives me the warm fuzzies. This method averages around 40 minutes to charge 100 and velocity SDs are generally 5-9fps.

Maybe on my next box of 100 I'll just dump with the Harrels and see what the SD is.
