Edit, I copied them from two sources and neither is very good.
Plus when buying a blank then theirs always threading it for the action as well.. if im not mistaken as i have never bought just a blank..
Correct as well as shouldering and crowning. The throw in the job of indexing the barrel so it's pointing up as opposed to left right or down and getting the case to headspace in this position and it seems like a lot. LOL
Dave is there a pilot shaft in the end of the reamer to keep it inline with the bore ?
Yes either solid like Randy said or live as in a pilot bushing attached to the reamer but allows the reamer tip to rotate inside it.
I've got a small collection of them but lost the lathe I was storing before I got up the nerve to run one in.
Randy is pretty adept at using them without the benefit of a large so it's not mandatory.
I could do the same for you to at the Rendezvous Jerry
It’s great to see a youngster follow in their mom or dads footsteps. Better yet to see the younger generations get involved in the shooting sports. Wouldn’t it be fun to see Trystan Williams in a match with Emma Wolf!!!
Mia is the wife / mother and shoots as well.
She top 20"f in at least 1 category at the 600 yard Nationals last year
Emma Wolf is a rookie, female , junior this was her first match ever.
Her dad Jason Wolf is the 2019 Two Gun overall, LG and HG 600 yard National Champion
He's also the 2020 Two Gun & LG 600 yard National Champion
Jason didn't shoot and spent both matches helping Emma
Glen Sterling Jr won HG at the 2020 600 yard Nationals.
Glen was shooting a new LG he built with a barrel block like you see on a true HG
Mike McBrid is a very tough competitor, he seems to run a tune that shoots extremely small or blows up.
Mike wrote the scoring program that most of not all clubs use for IBS 600 yard competitions
I had all these cases with the doughnuts loaded when i made this post.. i shot 25 of them awhile ago.. the doughnut doesn't seem to be affecting accuracy at all.. i went 10 for 10 on a 2 inch plate at 430 yards.. however i still want them gone.. so on the cases i just fired i ran my reamer in them.. what kind of suprised me was the reamer cut a little off each case just inside the mouth.. then wouldn't cut anything till it got to where the doughnut was. And then it was very little.. just suprised me it cut some off at the mouth..
BS on the earlier post IME that you won't get donuts using the LCD
A lot of what I'm saying may not apply to what a lot of you guys are doing because in my particular instance I'm running .0102" - .0105" necks on my Lapua Imp. I'm convinced it's a donut making machine, they're not horribly bad and they're not hurting anything but I'm sure some day after traveling several hundred miles and paying to enter a match they are going to become a problem if I dlllllon't cut them off occasionally.
So when you are running necks that thin you tend to be pretty careful about taking any extra off anywhere by inside reaming. Even if we size with an LCD then use the expander mandrel prior to turning we are getting spingback, out with the LCD and in with the mandrel so I seriously doubt we're getting all those imperfections "pushed to the outside" so we can turn them off.
When I turn the donuts off I set my cutter so it starts making a cut about halfway between the mouth and the neck shoulder junction and it obviously removes a lot of the donut but a tight pin gage verifies there's still a little left inside. A reamer would catch some more but like I said I don't want the cross hatch reamer marks or the cuttings in my necks and brass.
Perfect is not going to happen but I'm happy with manageable.
I've shot almost exclusively 40° shoulder cartridges the last 4 years. 6 BRA, 7-08 Imp, 6.5x47L Imp and a Dasher. With the exception of the Dasher being a no turn neck the others have all made donuts. For me the improved accuracy and the almost non existent brass growth is definitly worth the trade off maintaining donuts. I think the 40° shoulder inhibits brass growth because it's "balling" it up in that sharper neck shoulder angle.
Every 5 firings I size, trim, turn & anneal my brass and consider it fresh and good to go for another 5
When I shot that .865" group in competition at Elbow Lake MN and backed it up with a 1.2" then backed that up with a 1.778" four target agg to win LG Group, Score and Overall that brass was on it's 7th firing and had the above processing after it's 5th firing. A month later in the 2019 600 yard Nationals it had at least four 1" groups out of an 8 target match and the brass was on it's 8th or 9th firing or annealed + 3 or 4 firings.
After 4 or 5 firings it gets hard to get a consistent shoulder bump because IMHO I'm fighting the excess brass in the neck shoulder junction not because the brass is getting hard from lack of annealing so I process them at 5x
So as Forest Gump would say "That's all I have to say about that" LOL, my experience possibly worth exactly what you paid for it but the process is definitely working for me.
