Getting ready for the IDPA provincials and considering what ammo to bring.

Does anyone know if Winchester 9mm Luger 115 gr, FMJ Target/Range ammo will meet the ESP power floor?

Thanks

John

bullet weight = 115 gr times the muzzle velocity and divide by 1000 = Power
 
Valid question...I got a bit of a surprise at my last IPSC match. UMC 115 gr ammo just barely made 125 pf. Half the rounds we chrony'd were below the minimum. I confirmed this later with my own chrony and none made 125 pf. Winchester white box 115 gr makes 135 pf+. This is in a CZ Shadow.
 
Power Factor = IPSC : weight x velocity / 1000 = (125) Minor Power Factor

Power Floor = IDPA : weight x velocity = 125,000 Power Floor.

All of it is symantics of course.
Factory or not, I'd chrono it to make sure. Some 115 grain ammo won't make it.

:agree:

Obviously it depends on your gun. Every 124g I've tried has been good to go, but some of the 115g are pretty close to the minimum. You wouldn't want to get there and get a bad news story about your ammo.
 
Actually it does not depend on the gun... let me dig out the rule book...

Chronograph three (3) rounds at a distance of ten (10) feet using a
gun of MAXIMUM barrel length for the DIVISION of the same
gun type. If two (2) of the three (3) rounds exceed the power floor,
the competitor is in compliance.

Page 28.
So it should be a matter of record if the ammo in question makes the power floor.

Thanks for all who replied, I'm going with the 115 grain ammo.

From the IDPA rulz book

IDPA is a shooting sport that uses practical equipment including full charge service ammuniton to solve simulated "real world" self-defense scenarios

'seems pretty straight forward...

If you get chrono'd, your going to get chrono'd using your ammo in your gun. Good luck with your choice.

Not necessarily. I've been to sanctioned IDPA matches (more than one) where ammo was collected and I came to find out that it was shot over the chrono through a 'match' gun. Only if there was a problem was the remaining sample ammo fired through the competitor's gun.
 
I don't see why you would want to travel to a match with ammo that is so close to the minimum that you risk having to go through all sorts of gyrations with 'match' guns, etc. at the chrony station, and praying you don't have a cold day. One added piece of stress I don't need at a match. Get some ammo that makes 130PF and don't worry about it.
 
A few years ago I chrony'd Winchester White box - 115gr, 124gr and 147gr, none of which made 125 PF, however, I was ammo nazi at the IDPA Nationals last year and all bullet weight Win WW made PF by a good margin.

Chrono the ammo before yuo find out that you are shooting for fun.

That's interesting. I've looked at that rulling and wondered who would subject their gun to unknown ammo from a potentially unknown competitor. Unless it was a manufacturer's sponsored pistol that was used, I do not see it being reality for most matches.
I know as a MD, I've been happy to volunteer my guns and ammo for added fun on stages, but I wouldn't do it to run the chrono.
Have there been any clubs in Canada run it this way, or have all of those competitions been in the States?

Beltfed,
I don't think it is a matter of it being done in the US or Canada.....it is a matter of following the IDPA procedures for Chronying (sp) as laid out in the rule book, and dealing with a competitor whose ammo does not make PF ........and in following the guiding principle of giving the shooter the benifit of doubt

I used my guns for the chrono stage.
 
Chrony of ammo

From my understanding there are a lot of sanctioned matches that don't have a chrony component. However they have the threat of a chorny portion and that keeps most people honest.

I know for our club, that the way I will be running stuff is that as long as I don't physically note a long time for the slide to run, you are good to go, but that being said I do think that the rule should be in there and that the current rule is satisfactory.
