[QUOTE="royinidaho, post: 1153829, member: 2011"] No field experience though shifting weight/center of gravity forward is bound to have an effect of flight. Aluminum, depending on design, may shift center of gravity rearwards. Brass, the way I'm doing it, add 3 grains to a 350 SMK and 0.150" in length which I suppose would shift center of gravity somewhat forward but not significantly. Steel is ~2.9 times more dense than brass thus, for the same dimensions, would be around 35 grains vs 12 or so for the brass design. The steel tips in the above pic look humongous compared to what I do and may replace a larger amount of brass, depending on the shank. Lead is about 1.45 times more dense than steel and may not change the balance of the bullet significantly. Terminal performance is the reason for the brass tip though I'll take the significant increase in bc. The concern is getting SMKs to open at long range. I've learned that terminal performance can be significantly altered by the shape of the base and shank of the tip. The proof is in the pudd'n. We'll continue to watch for harvest reports. [/QUOTE]
