Odd reloading experience(titegroup powder)

[rocky]

Was out shooting my .40 S&W reloads. I loaded with 4.6 grn of titegroup with 155 grn bullets. The last round in 2 magazines failed to cycle the slide. Upon inspection of the casing and barrel, much unburnt powder was evident.
My guess is titegroup powder is indeed position sensitive to a clean /full burn(it was advertised as not so). atleast with CCI primers. .
Anyone else find similar results ?

That is weird. Maybe not enough crimp? Do you have evidence of gas escaping on the outside of the brass?
I use 4 gr of Titegrup for raniers 124 gr 9mm and winchester small pistol primers and had no problems. I have to go as low as 3.2 gr to have cycle problems in my PT-92.

i would guess issues with the primers in question titegroup works excellent even in tiny 38 sp loads i have had very little problems with this powder

the few i have had do as you said there was full powder but primer had popped and the powder did burn easily

Maybe a bad lot of primers. I know the 2 were form the same box . No gas leak evident on the casings. Either around the primer pocket or the case mouth. Hope most of em work right, cause I test shot the load, then loaded about 700 rnds. before this happened.

I use titegroup in 44spl and it
always burns clean with little
residue.In the past i've used it
in 45 colt with the same results
it didn't seem to be position
sensitive.

Being both the problem rounds were the last in the mag, I feel certain it is a case of powder or primer. Ether way, I am not getting a full burn occasionally on the last round fired.

I have had similar issues lately, but only with CCI small pistol primers? I was using Unique for a 9 mm. Is there a CCI primer issue out there?

[rocky]

Maybe. BTW, unique is smokey as heck compared to titegroup and a some other powders. (atleast in my .40 loads) Might want to try some different powders when you get a chance.
