I never shot the Speer Glod Dot bullets, but would guess that their 240 gn. bullets would be a better choice for deer. I have a box of their 240 gn. bullets and like the looks of them, but haveing shot about everything else on the market over the years, I`ve been useding a .44 mag since abt. 1980, I`ve settled on the 240 gn. Serrias. I seem to get the best combonation of accuracy and terminal preformance with that bullet in abt. every gun it`s been used in and since I load for afew friends that`s a fair number. I have recovered 1 of them over the years and it was from a nice 8 point buck that was shot at 135 yrds. in the right hind quater and the bullet was just under the skin of the forunt right shoulder. It had expanded nicely at that range. Gun was a 7 1/2 in. barreled SBH. If you hunt bear I would save the 270`s for bear and get some 240 gn. bullets for deer.
