Fiftry driver: I've built both 25 STW and 257 Banshee's for customers. I personally feel the Banshee has the edge, course then you have the fire forming and additional cost of brass. Nothing for the didicated LR shooter.... My guys are mostly speed freaks rather than the BC from the heavier bullets. Local customergot a Prarie Dog at 1080 yds this year so he doesn't want to here remaining velocity and BC from me. He's using a 90 grainer at 4200 from a 30" Lilja bbl. As long as he keeps it to small varmints guess I can't argue. He uses the 100 gr. BT for Deer @ 4100 fps. Told him he is trading on the high side pressure wise. Claims his Hertenberg brass Primer pockets last longer than the RWS. I've had no PP problems using the 100 gr.BT's at 3850-3900 and can keep 3 shots under an inch at 500 yds... Ever done any Banshee's ?
