I've been running between 2800 and 2900 with the 147g ELD's in my RPR using Superformance for quite a while. My loads are still below the max load by .4g and are SAAMI length also and show no pressure signs and consistently shoot low .5 MOA's at 800 and 1000 yards. I haven't seen any evidence of bullets disintegrating either. Did the OP ever mention what gun he is shooting?I had issues at 2800 with them.
