View Full Version : Keyholing on reloads
09-29-2005, 08:25 PM
I finally took my reloads to the range today. The Hornady 35 gr VMAX over 6.6gr of HS6 in once-fired brass with CCI small rifle primers were keyholing on the paper at 7 yards.
Let's just say I was disgusted. This caliber has got to be one of the biggest PITA that are out there for reloaders. Will some major company PLEASE come out with some virgin brass and proper reloading DATA?!?!?!?!?

almost 24 hrs and no response ???
how about I start with some questions
any chrono info? how does it compare to RNelsons 6.6 grain MV measurement?
does it settle down and NOT keyhole at 15 yards?
does it do it every time or most of the time or once in a while?
more info and pics appreciated
and one more thing (grasping at straws) - Im curious if you would - eject a chambered but not fired reload & check oal - see if theres any change in OAL from what it came off your press.
& speaking of oal, the 35 grainer is super short compared to the factory loads & possibly not enough neck holding onto it or if seated a bit deeper then you have a bigger jump to the rifling
sorry to hear your troubles.....

I have never seen the 35 gr or the 40 gr V-Max keyhole. What is your C.O.L. and do you tie your target down or do you just hang it from something. The reason I ask is that the bullet could be pushing the target before it goes through. I see this quite ofter with 9mm and 45 cal bullets, although it doesn't seem likely with such a small sharp bullet.

The chrono info was similar to the results listed in the other thread here. It only keyholed a few of the rounds. The OAL didn't change -- there was no bullet set-back. The target was hanging but it had a cardboard backer so it didn't swing or push at all. I'm confused, but at this piont, I think I'm going to stick with factory SS195 ammo for a while to see what happens with the reloading results of other people.

I am using True Blue, and also Vinta Vouri 3n37 and Berger 30gr, Vmax 35 and 40 and find no problem with any of the loads. I favor the 3n37 and the results match the results of sulafool. I have followed his results with great interest.
I don't ream the primer pockets to remove the stake. If you have trouble seating a primer turn the case and seat the primer which will almost always seat at some point while turning the case.
I find the gun to be a excellent shooter with little difference as to the point of aim after the first adjustment of the sights. It seems anything between 1800 and 2000 shoot to the same point of aim.
I load for several guns from a 50 BMG, 45acp, 50-100, 45-70 and many others and this is a fun gun to load and shoot.
