[QUOTE="royinidaho, post: 346455, member: 2011"] Kevin, Thanks for the info. I got the price from Sierra's web site. What's your project here, anyway? There isn't a bullet maker on the face of this earth, that has shown him/herself, that makes a 270 Cal VLD/ULD 170 Class hunting bullet that is robust enough to consistently stand up to the rigor of an 8 twist 3 groove barrel. The bullet making industry is pretty set in its ways with little desire by the makers to tackle such a small niche market considering the high initial costs. Thus I came to a brick wall and am attempting to build a door to get through it. Conversations with the barrel maker indicate that more robust jackets are the solution. I've been turning them out, in the experimental state one-off on the lathe. I've been using pure copper rod and a reamer that Dave Tiff make to my specs. So far so good........ I figured that the Sierra jacket, would be possibly enough tougher than pure copper. When drawing down to 277 from 308 thickness could go up to as much as 0.0356" which is very close to the 0.040" base thickness that I've started with. I'm using a straigh taper. Questions lead to more questions which lead to challenge after challenge.:rolleyes: That's my project.:):rolleyes: Roy [/QUOTE]
