[QUOTE="J E Custom, post: 265190, member: 2736"] After reading buzzguns post I had to settle this issue for my self. I am and allways have been suprised by the performance of the 120gr ballistic tip so I decided to prove it once and for all. This is the way I did the test. First I cut a piece of 1 and 1/2" stainless pipe 1 inch long. Then after sand blasting a 120gr and a 140gr NBT I placed them on a piece of granite protected by release agent . Then I placed the piece of stainless pipe over the two bullets. Next I mixed up some devcon and carefully poured the devcon in the pipe and coverd the bullets. After cureing I placed the specimen in my lathe and started facing it off .005" of an inch at a time to keep it cool and not disturb the bullet or the core. After cutting almost half way through I took demensions using a 6x magnifier and a electronic vernier. I had expected to find a thicker base on the 120 but they were the same(0.152 avg). Next the wall thickness in 3 different locations. the readings for the 120 was 0.053avg and the 140 was 0.041 avg. After getting these readings I faced the test specimen down to the center line of the both bullets for my finial readings. The 120 wall deminsions were 0.043 avg and the 140 was 0.031 avg. So the 120 gr NBT definitely has a 0.010 thousandth thicker jacket than the 140gr NBT. By 20 + percent. This test explaines a lot to me and puts the debate to sleep as far as I am concerned. I know it was long winded but I wanted to make this test as accurate as possible and unbiased. J E CUSTOM [/QUOTE]
