	a question for you guys shooting 32-40 chambered by cpa: what case length is optimal? currently after 2 firings my cases are at 2.110 which comes in a little short of Lyman published trim to length. I am breech seating all loading. just curious as I experiment and develop loads, thanks

	thanks, someone gave me a quite different length than published (Lyman = 2.120) and I was double checking. I think they misunderstood my question. 2.120 it is. thank you again 40 rod

	didn't see J louis response until I responded . 2.130 is still very different than what I was told. Regardless, Lyman published specs are within the needed parameters. I will be shooting and monitoring the growth of my case sprouts this spring. I might just go ahead and chamber cast too. Again, mostly checking against a number previously given to me that was incorrect by a long shot thanks Jlouis

	Don’t worry about the length of the case, a 32/40 case will shorten after a couple of firings, it may go from 2.130 to 2.115, we have been told that cases get longer after firing, that is not true with the breechseated 32/40 case. Ledball

	Amen Ledball and length is really not all that critical if being close for what we do.
