Last post by sean30ber -
Ok, pretty happy with this out of the Savage. Now I have two long range hunters. Berger VLDH and Sierra Game changer. Both under .4 with this gun.

Im calling it good for hunting. Will run a 10 shot group next Saturday just to verify.

Reloading / Re: Mandrel flaring end of neck?
Last post by bikemutt -
I couldn't get satisfactory results with a bushing die, seemed like there was always something going goofy with the necks. Since I don't turn necks I took the lazy way out and went back to using a Lee collet die. For the kind of shooting I do the Lee die is good enough.

I have noticed this on my brass as well. I use a bushing die as well. I’ve noticed it with an expander ball and mandrel. I borrowed a buddies Lee collet style neck sizer and the flare went away.

It’s not a chamfering issue. My thought is it has to do with elasticity of the brass and spring back. As the expander ball or mandrel is pulled out of the neck the brass pulls back to a smaller size. Since there is no brass past the lip of the neck it doesn’t have the same amount of tension to bring it back to the same size as the brass below it.

As the expander is pulled through the brass its smaller on both sides of the ball. The top side because it was sized down, the bottom because of spring back making it slightly smaller the the expander. As the expander/mandrel leaves the neck the area at the opening doesn’t have the same amount of brass to help pull it down in size. Not as much spring back. At least this is how I see it.

I live with it since it is a constant. I use the collet die if I need to check neck thickness as it makes sure I don’t have the flare at the end.

Have you checked case lengths?

I had a batch of in another 6.5 brass grow so long after more than ten reloads that the mouth was trying to push into the chamber throat.  Needless to say I got some interesting pressure signs.

The flaring might then have resulted from your cases having become a skosh longer than expected.

Thanks for the thoughts all around guys,  will check all of this again tonight and see what the story is.

If it was extending beyond the bushing, then it should be flared before I put the mandrel down it, but its not, so I suspect that isn't the issue.  The fact there might be a ridge on the inside of the neck like Fuj mentions is certainly possible though.

Fuj - right now I neck, mandrel, inside/outside chamfor.  (This is assuming they don't need a trim, which is almost always).  Do you chamfor before running a mandrel in?  I wouldn't expect them to have a ridge on the inside of the neck but i'll pull a dental pick over a couple tonight and see if i can feel something.

I full length size in my custom chamber die. Neck was honed so that
there is no excessive movement of metal for the mandrel..... Cases
are then trimmed to length, chamfered and deburred. My chamfer
tool does both inside and outside. I usually take scotch bright to the
cases to remove any shavings, air blast, then to the mandrel die.....
The problem I had was from a dull cutter. The chamfer looked good to
the eye but, instead of a clean cut, the cutter left a rolled over edge
to the inside. I re-ground the cutter and also gave it a steeper angle.
It cured my problem.

Congratulations sir on a fine outting.
As a long time ibs member and participant of the natuonals and the world open o can tell ya.
Everybody brings theyre A game.
I kinda figured the little 6mm would do well but i was surprised to not see a 30 cal in thr top spot.in either heavy or lite gun. I still love a big bore ,when tuned ,they will out perform anyrhing.
I didnt go this yr. Too far for me. But if the winds kick up they are still one of the top performers.
But if it was calm like the last day of last yrs nationals then you see the 6mm come ALIVE.

Reloading / Re: Primer Seating Depth
Last post by Fuj -
As Jerry mentioned in his previous post, attempting to assess the effect of primer seating on group size, particularly at 100 yds where most load development is done, is not going to be very fruitful. Any change is going to be so small that it will be masked by other variables. However, the effect on ES is readily obtainable with any decent chronograph. So if you're developing loads with the goal of having consistent POI at long range (1000+ yards), assessing any variable that might reduce ES would seem reasonable and not all that OCD.

Yes Sir !!
