[QUOTE="Wedgy, post: 1688812, member: 64108"] Speed will generally pick up after 20-50 shots on a new barrel. Also I have found Reloder 33 to pick up pressure very rapidly above ~84F and it is also very dirty requiring cleaning more often than other powders, developing a carbon ring in the throat can do what you are describing also. I f you let a round sit in a hot chamber it will boost the temp and pressure. Seems like N570 has been a good powder for the 28 Nos. [/QUOTE]
