I have had very good field service from my Deerfield using the Speer 270 grain Gold Dot load. Flawless performance and good accuracy from the rifle, good game performance from the cartridge. Both shots were close. Both deer killed with 1 well placed shot, both complete penetration. I do not use the scope protector when hunting, and have found that the ejected brass does hit the scope ( 2 3/4 Burris) by not using the cover during sight in at the range. There is no serious damage, in fact, the marks are almost not discernible, and are on the very end of the adjustment cap. I do routinely use the cover for target sight in, however.
