Just picked up a box of the latest and greatest from Nosler. A box of 180 gr 30 cal E-Tips. I'm going to work up a load with them in my 300 WSM while I work up a load for my 168 gr TTSX's.
They are a similarly constructed bullet, monometal with polycarbonate tip. No grooves in the E-Tips and they are supposed to foul a lot less than the all copper TTSX because they are made of the same alloy as the jackets of their other bullets.
The 180 gr E-Tip is a long bullet, about 0.1" longer than the TTSX. I wouldn't want to load one much longer. The ogive of the TTSX is narrower than the E-Tip.
180 gr E-Tip, BC = .523 and the 168 gr TTSX, BC = .450 (approx). After weighing 50 of each, the E-Tips were slightly more consistant with a range of 179.5 gr to 180 gr with most being right about .1-.3 less than 180 gr. The Barnes were 168 gr + or - .4gr
It should be interesting to do this comparrison. Hoping to get 3050 fps out of the E-Tips and about 3150 out of the TTSX's. Both Barnes and Nosler claim near 100% weight retention from these bullets.
Wonder if anyone else has tried the E-Tips yet?
Will keep you posted of my results.
