Name these two bullets - 30% different mass, same bc

107 gr 6mm - .243 Sierra HPBT MATCH
140 GR 6.5mm HPBT MATCH
MY GUESS.... Theosmithjr
They're definetly HPBT MATCH KINGS, I'd bet my weenie the L is a 6mm & the R is a 6.5mm
6mm 110smk and 6.5mm 142smk.
I'm with you on that, I have both and it fits

I hate to break the news to your wang, but it's not a 6mm and the second is not a 6.5.

The clues in my OP are pretty revealing if someone does the #'s.
 
Guys the left bullet is the .257 ace bullet
The right bullet looks like a 7mm so I'm thinking a 180 Berger, probably the hybrid by looking at the shape.
G7 is close I think.
131/180 is 72% of the mass
About a 185gr would be right so maybe a 30cal 185 hybrid

Guess things should be pretty streamlined for me then. Been shooting the 170's out of my 270 sherman and I'm currently building a 25sst to shoot the blackjacks and maybe try hammers in.
