I had a few cases that I could not get right, so I think I have cases that are not the same thickness all the way around. I needed way to check this, being a cheap SOB, I made me one. Took the mandrel from a 7mm Lee case length cutter, drilled and taped the base block and now have a case neck thickness checker.

It as to to do with the barrel whip, as a bullet or boolit travels down the barrel it will bulge, harmonics are diff for each diff round. Just works your loads and remember where they hit. 

Best bet is to make what you want, ya gona have to keep the grain straight for the best staff.

Was in on a build years ago using the same fuel, we used wood bung plugs, till we put a hole in the side of the shop, it was heavy sheet metal. Boss was a bit pissed till he saw how we did it.

As a person that lives in the 3rd most free state in the Union, they can bite me!

Ran 50 unloaded cases in the RCBS die, all less than .001 run-out with out the expander ball. Reran a few with the expander ball and the .004 to .007 run-out came back, so ran them in the sizer die to fix them again. Now I have a Lyman 7mm M die expander that kept the run-out below .001, however I did find 7 cases that has run-out after the M die, ran the 7 with the Sizer die back out a bout 1 turn, case are straight again, back into the M die expander, run-out came back. These 7 cases are now culled for brass thickness not being the same around the neck. This rabbit hole is very deep, gona be a long road to HV.

In checking my cases I did find that my Lee die is making the case necks run out. Ran a few in a RCBS die and fixed them. Lee close to .003 to .005 out. RCBS less that .002, most less than .001 out. I did rotate the cases 180* and ran them twice. One step closer to 2500 FPS with powder coated lead. I am gona have to find a neck die for this rifle.   ETA: checked a few fired, unsized cases and found my chamber has .001 run-out, not perfect but usable.

Caster is right, accurate groups start right after the pin hits the primer and ends when the bullet hits the target. If the bullet is not straight going into the lands it will come out of the barrel not straight, depending on the twist rate of you barrel, the bullet rotates at mind blowing 150,000 RPM, think about you tire just a little bit out of balance.   Bullet RPM Formula Here is a simple formula for calculating bullet RPM: MV x (12/twist rate in inches) x 60 = Bullet RPM Quick Version: MV X 720/Twist Rate = RPM Example One: In a 1:12″ twist barrel the bullet will make one complete revolution for every 12″ (or 1 foot) it travels through the bore. This makes the RPM calculation very easy. With a velocity of 3000 feet per second (FPS), in a 1:12″ twist barrel, the bullet will spin 3000 revolutions per SECOND (because it is traveling exactly one foot, and thereby making one complete revolution, in 1/3000 of a second). To convert to RPM, simply multiply by 60 since there are 60 seconds in a minute. Thus, at 3000 FPS, a bullet will be spinning at 3000 x 60, or 180,000 RPM, when it leaves the barrel. http://bulletin.accurateshooter.com/2008/06/calculating-bullet-rpm-spin-rates-and-stability/

Well I did check Jacketed loads as well, I am thinking something is wrong with reload process, size die is on the list to check.

Ruger SBH, stainless, 44 mag, load lite or heavy, run to shoot. [URL=http://s896.photobucket.com/user/redintn/media/pistols/SuperBlackHawk44Mag_zpsd0e3a7c0.jpg.html][/URL]

I hate to tell you this, you will not use it again, when you do need it, it will be forgot or lost. :rofl: Golck55 if faster than me.

On another forum the talk is high speed cast boolit shooting. I want to push my 7mm RM to 2500 FPS with a powder coated cast boolit that I make There was a post about "runout" and reloading. I have not been reloading long, thought I was doing a good job. Well now I am a bit ticked off as I have not been paying close enough attention to runout as I should. i did not have a gauge, do not have the money to buy one, so I made one. Old heat sink, dial indiactor from my Cabin Tree hardness tester. It is not good looking, but does work, it did show me that 2 in 10 rounds I checked are under .005. The rest are .010 and more out. Back to learning how to reload for groups before speed. If you projectile does not engage the rifling square it will not group.

Pistol came out great, and I to had diff thoughts on the post title. I was thinking of a trip to the Doc to get the stuff off your hide.

So you used my idea and now where is my "Idea" check, do you need my payPal address, I think 6,000 dollars will cover it just fine. :cool: :yum: :wave: :rofl: Glad you got it fixed, now yall will be warm when ya want. :rock:

If the socket is to tall, grind it shorter. It is a do able job, just a PIA.

1.5 hours for me, think I will pass.

Shipping is gona be the bad part. http://www.midwayusa.com/product/2900372783/winchester-231-smokeless-powder I know you are looking local, just an idea.

If I remember the Feds were trying to get this very same some time ago.

The very reason I stopped going, and the fact David my supplier stopped going. I could make the trip in November, any one else?

How about a road trip for the next K town show?

Got to play to win, I am playing!

DUMBA$$ is about all I can say.

Congrats to your wife and you for teaching so well.

I read the rules and reload might not be allowed, any word on this from someone that has been there.

Well aint that about cool, congrats David.
