Re: First time for everything 1000 yard group
I use the plain jane RCBS dies with the FL die. I do not have a neck die yet, soon, very soon. I use a Lyman all American turret press that my father in law gave to me years ago. My headspace is set at .001".
The brass that I am working with right now is second fired, so after the shot it is third fired. This next thing is debatable, however it is what I do, and seems to be working. I weigh all of my brass, and separate it all to the grain, I do not always do h2o water capacity tests, but sometimes I will do a few just to get an all around average. This is all done after they are resized, and trimmed, which I do every time. I never trim to min trim length it is usually closer to max, but all must be the same. (example if min length is 2.40 and max is 2.50, I try and get them all to 2.45) It didn't sound right the way I wrote it.
I weigh and seperate all of my bullets.
I use a charge master 1500 to dispense my powder, and then I check it on my RCBS 505 scale everytime. If the 505 doesn't register exactly zero I throw the powder back into the charge master, and do not dump into the case until it is exact.
I'm sure that all of the things I am stating are common practice for most
My Chrony readings yesterday where in order: 3087, 3089, 3089, 3087, 3089, 3100. The temp was at 60 deg. F ( I don't know if the temp has anything to do with that consistency, I added that fact because I do use US869) This almost amazed me more than even hitting the target yesterday. I had this happen one other time with this powder in the past where shooting a 168gr VLD I hit 3208 4 times out of 5.
What I am wondering is if that 3100 shot is the one that is high and right of the bullseye? I wish I could see them hitting, because that would be interesting stuff.
Bullet seating is done very slowly, right when I start feeling the slightest pressure, I back off a bit, then I run it back up slowly until bullet is seated. I think it may help with the concentricity.
That is what I have been doing so far. I am probably just getting very lucky. I am going for a longer shot tomorrow. I will post results, good or bad.
