My father picked up a good order of reloaded 9mm FMJ and 45 ACP FMJ from Wolf, and we are more then a little mystified once we started using it.

We started shooting the ammo when we got it mid-winter at our outdoor range. (-15 degrees c)



We noticed immediatly that the 9mm was shooting consistantly 9" low out of our brand new CZ SP-01 Tac at a range of 10 meters.

The 45 was also shooting low, consistantly 3" down, out of our brand new Norinco 1911 A1C, also at 10 meters.


We were unsure what was going on, so we tried all manner of solutions over several different weeks, from lazer boresighting to benchresting, but the loads were consistant for both calibers.

To see if it was the ammo or the guns, we tried 50 rounds of Remington Express out of both handguns, and both calibers fired dead on accurate every shot. We swapped right back over to the Wolf reloads, and they fired low again.

We got mrclean, a member of our range, former IPSC champion, and now the go to guy for IPSC in Ontario, to try both the guns. He confirmed that they were indeed shooting low.


Now, just to really throw a curveball at you guys, we went out a few weeks ago during that two day warm spell, where everything warmed to just above freezing.

Get this...

The Wolf reloads started shooting accurately! Out of the blue, for a whole month, they don't work, and one day they work perfectley.

After the cold snap was over, and it went back to -10 C, the ammo started dropping again. We haved stopped shooting for now and are waiting for a warm day to try them out, just to reconfirm that the issue is temperature related.


Has anybody ever heard about temperature changes so drastically affecting the accuracy of a pistol round over such a short distance, and is there anything I can do to reduce these effects?

Tell me what you think is wrong guys.

guess you should ask wolf now to use powders that are senative to cold when you order from him again, ask for a sperfectic powder from now on, and ask him what powder he was using, so i won't go out and buy it lol for my relaods
 
Yep powder types make a differences. I dont' know if has other loads with other powders to push that same bullet, if he doesnt' he's not just going to swap powders and go, I believe he has to have each load approved before he can sell it.

If you have access to a chrony check speeds for different temps and you will see the difference.
 
Have you contacted the supplier and asked him?

That is my next step. I just want one warm day to confirm that it really is temperature that is causing the issues, not some other factor.

If you have access to a chrony check speeds for different temps and you will see the difference.

I will see if I can gain access to a cronograph to see what is going on.

how many rds did you shoot per session?

100 rounds/ session.
