I shot a 150 rounds today that were 1.165" OAL. Did this to reduce pressure do to the high ambient temperature. It did the trick. Pressure was reduced, accuracy returned, no problems feeding.

Shot a practice USPSA match and went through about 100 rounds without a hitch.
A very soft, pleasant load. I have to get out with a chronograph to see if it actually makes minor power factor.
raz-0 said:Ok, I have a word of caution regarding light loads.
Keep your magazines clean if you try them. They aggravate dirty magazine problems given the design of the mag body and follower.
I have to say that reuslts would indicate you should keep it to SAMMI OAL or less.
I feel better now. I was trying to figure out why you had that for a spec, but everything I have says oal basically between 1.125 and 1.135. Over in the forums at brianenos.com, there are some people reloading 40's way over max oal. Not sure that I'm that brave yet, but it is being done. I'm not in any hurry to do that anyway, as I'm currently shooting major, and without a chrono, I don't plan on switching to production and cooking up some minor pf loads.raz-0 said:1.133 inches isn't longer than SAAMI max, SAAMI max is 1.135. For some reason my brian thought it was 1.125.
Ok, this topic interests me. I've been loading strictly within specs, but am interested in the effects of changing the variables within reloading. I seated some bullets in some empty cases and found that 1.175 oal length rounds still fit in the magazine, feed and chamber. What is it that leads you to believe that the USPSA loads shouldn't be considered? Don't take me at all wrong, I'm not in any way doubting your findings. I'm just curious as to what leads you to this conclusion as a matter of education, not doubt.raz-0 said:Frankly after doing load research I'm almost of the opinion the standard USPSA loads for a 2011 or para shouldn't even be considered .40 S&W anymore.
Only a couple of rounds.raz-0 said:Those 1.175 rounds, how many you load in the magazine at start?
180g FMJ and 180 cast TCraz-0 said:What bullets?
I shoot IPSC, so when it counts , there will be movement.raz-0 said:Are you doing fast reloads that might jostle stuf inside, or are you casually shooting from the firing line?
That is exactly the info I was looking for. I'm currently shooting Limited 10 Major, but might move to production. The info you've given me will help me to better explore my options for shooting minor pf. Thanks a lot.raz-0 said:Any of that stuff can make a difference in what will fail to function.
