FWIW JB I have no way to pressure test so I worked up my AI loads slowly and carefully..H335 is the only one that ever showed excess by blowing primers. My max load of TAC or IMR4895 has never given me a bobble...at any temp.
Same here. I worked up a load with H335 for the 22-250 in the winter and was blowing primer shooting Pdogs on a hot summer day.
In the AR I've had H335 loads that were fine in the summer fall fail to function on cold winter days. My experience seems to mirror Johns that H335 is sensitive to both heat and cold.
