I have lots more SRPs than LRPs - I bought Starline small rifle primer brass for 260, 308, and 65CM. Starline may not be Lapua but works for me. I use more Alpha brass now anyway for PRS.
Shows how out of the loop I am. I didn't even know Starline was making SRP 260 brass. Guess I need to buy some as I have SRP stacked pretty deep.
