Updated with Hornandy XTP
I’m starting a new thread for this post because I thought it might intrest more than just reloaders.
Shown in the picture below (from left to right) are:
- Speer 124 gr TMJ bulk bullets
- Berrys 124 gr HBRN/TP bulk bullets
- Federal 115 gr FMJ pulled from factory load
- Sig 124 gr V-Crown pulled from factory load
- Hornandy 124 gr XTP pulled from factory load
My observations from this are essentially meaningless but still a little intresting to show the difference between quality construction and plinking rounds:
- The lead in the hollow points seems harder than the others as they did not gall during lapping like the others did. They also appear to have a higher density due to having about the same physical cross section as the 115 gr Federal.
- Federal factory plinking ammo has the least plating of any of the rounds shown
- speer and berrys bulk bullets plating is about twice as thick as the federal FMJ
- the v-crown bonded & XTP jackets are orders of magnitude thicker than the others and if you look at their bases they are extremely thick (comparitively). I expect the material in the wall thins as the jacket is drawn up while the base maintains it’s original thickness.
The thick jacket base should help maintain dimensional stability under pressure.
And there you have it. Factoids for everyone.
