i had the same problem w/ the rocky mountain revolutions. i got about 4 inches of penetration on a 60 lb doe back in 2000. the shot was only 10 yards. i purchased the heads b/c they were out of rm assaisans, which i have had good luck using. in 2002 i bought some rocket steelhead 100' s. unbelievalbe results. passthroughs on 4 deer and a good bllodtrail! my faith in expandables is restored. however, i have read that the snypers were good heads.
