I have shot them out of a Savage bvss with a 9.25 twist. I shot several 5 shot groups in the 4." area at 600 yards in a couple of IBS match's with them. I found that my gun would stabilize the 107 SMK, and I liked them much much better. Looking at load data published, they have about the same max load but the heavier bullet makes the trip much faster, and shoots flatter. This was very obvious at 1000 yards. Your gun may or may not stabilize them. I never tried it, but heard that people have had good luck with the hornady 105 a-max in a factory twist 243. You may want to look at the 108 BIB bullet, they are for slower twist barrels. I was able to keep them together in my fast twist 6x47L and shot some very impressive 5 shot groups around 2." at 600 yards. With all that, I don't know if any of them would be a good choice for deer. Good luck I hope this helps.
