the load is good! Five rounds from 900 yards.

I held center mass and was just enough wind to drift group little left from center.

What magnification did you use for that group?

I doubt it, but when quartering a high contrast target of regular shape, it may not take as much as you think either.

That is a big target.. Good shootin though.

It is superb shooting, never mind the magnification.

And a lefty too. Great shootin.

16x With 200 yard zero my zero at 900 is 22.5 MOA on the NF scope.

Looks good going by me. Nice shooting.

Target is 32” x 34” depth! I want it that way for a reason! We get bad fishtail winds here quite regularly and my game is seeing first shot hits and if I’m off on a wind call I want it on that piece of AR500 to see a correction factor! When my son and grandchildren wanna play we go to the 5 and 3” plates from 1000! We shoot eggs on a stick on occasion!

Here's another from the day before.

Great shooting!

Sharp, I understand you know what you're doing very well. That wasn't why I asked what I did.
Posted By: Sharpsman Re: Me thinks..... - 05/11/22
math man

Not a problem.

Crazy tight vertical, good load is an understatement!

^^^ This! ^^^

Great shooting!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

(Exclamation points for Skane!!!!)
Posted By: xphunter Re: Me thinks..... - 05/12/22
Impressive for sure.
Good to see another lefty shooting well.

A very important little tool toward safety and accuracy….head-space guage! I’ve checked some brass in previous times whereby the case was as much as .010 too short compared to correct chamber size from the firearm it was fired in! My experience tells me that the major cause of case head separation is because loaded rounds are fired using cases that are too short! Some times the bullet will be seated overly long which helps to a degree to prevent this because even though the case is too short the case head will be pushed back against the bolt face when ignition takes place! The shoulder will be blown forward to expand the shoulder area! I don’t therefore like loading ammo with undersize (length) cases! This little tool or one like it removes the guess work of setting the resize die such that the loaded case is matching the chamber from which the case was fired in! In retrospect, when first being taught how to set up ones dies the new guy is told to insert the resize die into the press with proper shell holder, move the ram of the press upward to max height and then screw the resize die down to touch the top of the shell holder then back the die up such that a gap between the top of the shell holder and the bottom of the die approximates the thickness of a nickel! In my judgement that is guess work! I didn’t win matches by guessing; rather I won lots of garbage by paying attention to detail!

So, if you have to fire said brass in order to use the case gauge, does the safety part come in on the second firing?

False shoulders from the start and chuck the gauge. smile

I'll let you figure it out! Must be the air out there!!

Were you having a problem with case head separation?
Posted By: Sharpsman Re: Me thinks..... - 05/13/22
No!
Posted By: Higginez Re: Me thinks..... - 05/13/22
Sharpsman, I think I put you on the defensive and I didn't mean to.

I should have said I agree with you on headspace being rather important and that I do it a different way.

Please accept my apologies Sir.
Posted By: Sharpsman Re: Me thinks..... - 05/13/22
No apology needed! I have skin akin to a Rhino.
Posted By: ERK Re: Me thinks..... - 05/13/22
When I first started reloading my 22-250 and 300 mag I had case head separation. The cure was to simply back the die out a bit. Over working cases I was. Edk
Posted By: CGPAUL Re: Me thinks..... - 05/13/22
Yep, that`s what I was thinking...bad wind call.

Nice shooting.
Posted By: Higginez Re: Me thinks..... - 05/13/22
With the Whidden case gauge, you measure against Go/No Go Gauges? Or do you just go off the reamer print?
Posted By: Sharpsman Re: Me thinks..... - 05/13/22
I take a reading off the fired case! THAT is the chamber dimension for that rifle or the headspace reading!. The reading will generally be at the 0 reading of the gauge or damn close to it! I adjust my resize die such that I get that same 'reading' on all of the fired cases that I resize. Generally I can get maybe three firings or so before I will have to bump the shoulder back a bit for easy bolt closure!
Posted By: mathman Re: Me thinks..... - 05/14/22
For many of my cartridges I just invert a 40 S&W case over the case mouth. The length of the whole shebang is my reference number. I size the rifle brass and check again with the "40 gauge." The difference in the lengths is the amount of shoulder bump.

Sounds very similar, if not the same as the RCBS Precision Mic.

Big target or no, that is a small group for 900 yards!

900 yards is a really long way out there! Ice groups.

I do this with some cases but use a shellholder. Shell holders have a big enouph hole that it fits 6.5 and slightly bigger calibers. Works great! For checking headspace I'll measure a new piece of brass than use .5 thou scotch tape on the head of my bolt until I get pressure closing the bolt. My new rifle I just put together headapaced 2 thou with new lapua brass.

Nice work sharpsmen! I hope I can get mine to shoot that well!

I'm leaning more toward God let your kingdom come than save the USA! I'm not sure if this mess can be saved?

OUTSTANDING Shooting at 900. Target size means nothing when your stacking them in there like that. Group size says it all. Your explanation for target shape and size makes perfect sense. Much easier to spot when getting dialed in while trying to read wind/mirage down range
