My question is this. Other than the lead tip. Are there any other differences between these two bullets dimensionally, or otherwise? If not does the lead tip really make that much difference in the B.C. ? Looking at the published B.C.s and trajectory doesn't really match my experience shooting these two bullets side by side out to 300yds in the 300 win. mag. . I just don't see a measurable difference in trajectory. I have a hard time seeing the soft lead tip even suriving the trip down the barrel at 3000 plus feet per second. Also the same set of questions applied to the 200gr. .30 cal Partition component bullet and the 300 win. mag. 200gr. Partition in the federal premium high energy load. Any comments or obeservations will be welcome, and of course facts will be appreciated.
