OK, Lets try to sweeten the deal, I will go two for one,example I will give you 200ea ACP's for 100 GAP's. Any takers???? Hi, Looking to trade once fired mostly Federal 45 ACP cases for once fired 45 GAP cases. Let me know if your interested & will do a count on them. Has to be at least 4-5 hundred in the basement. Thanks, Rick I double checked & it seems that most of the cases are Winchester not Federal, Sorry.
