H335 and temperature changes - - More Questions

Loads with 25g of 335 that I worked up in March at 75 degrees shot just fine yesterday at 109 degrees. My best loads have always been back behind max so maybe that's why I have never observed this 'temperature sensitivity' thing that I keep reading about.
 
kelbro,
I think you may be onto something there. I thought about this last night as I was typing but didn't put it. I notice that others that are having problems are exceeding the max loads suggested. The only load that I have at max load is the load for the Stevens .223 at 25.5 grains of H335 under the 55 Vmaxes that was my best accuracy but I am finding that all the other loads I have experimented with my most accurate results have been below the suggested maxes. speed is worthless to me if accuracy isn't there. Accuracy is paramount.
 
I want it all.Speed and accuracy.Maybe that's why I have eight different kinds of powder for my .223 and still keep tinkering. /ubbthreads/images/graemlins/laugh.gifI have to admit that I have yet to find a powder that will not shoot good in my .223 although I have found a bullet or two that are less than great.H335 shoots fine but there are so many others that are cleaner and less sensitive so I have used it less and less.

Same here CW. When I can cloverleaf at 100, I don't often do much further load development /ubbthreads/images/graemlins/smile.gif . And I still don't know where all the talk about H335 being 'dirty' comes from. I have thousands of H335 rounds through 3 different barrels and as far as I can tell, it's no dirtier or cleaner than any other powder.
 
Kelbro,
I went nearly 500 rounds with H335 without cleaning the gun one time. The accuracy never fell off until then so I didn't bother cleaning it. I can't imagine it is that dirty. I bought it cause I heard from here that it was a cleaner burning powder.
