.308 154gr BBT
« on: October 05, 2018, 10:45:25 AM »
I just ordered a 2 cavity .308 154gr BBT mold for NOE. Should be here next week. Once I get some cast and tested I'll post it up.

Quick delivery for the mold. I laid one of the 135gr BBT's into the mold just for comparison.

Had a casting session this morning. The new mold is dropping these at .311/.312 on the lower band and .309 on the upper surface. I purchased lead from Rotometals in the 1:40 to cast these. Weight is 150.5gr.

Fresh shiny lead in the morning is like victory!  Mighty purty.  I bet Steelhead is looking at this lead and thinking oh yeah, send me a couple dozen to try in my Texan .308...  8)

Yes, Steelhead is sniffing around. I've considered pouring my own; I already have the lead pot and equipment for making spoons and jigs for fishing. In all honesty, I'm still working on more tangible things like which size bullet my gun likes to eat, specific air pressure for best performance, etc. 

There's so much more for me to learn about performance, accuracy, and shooting technique. When I first got my gun a year and a half ago I was making too many changes at once and it was hard to keep track of what was working and what was not.

When it comes to bullets for my .308 Texan the most consistent and accurate have been 118 gr. cast flat point.

That being said, there's something to be said for the satisfaction of making your own projectiles... much like tying your own flies, building your own lures, etc.  I tip my cap to those that do because they've already acquired the basic skills of how to tune/work on their gun and how to use the data that the gun is feeding them.

If you had a .457 or .458 I could share a ton of lead to experiment with. :)  It's hard to not get obsessed with pouring your own bullets.
