Can you purchase jackets only from Hines ? As far as I can tell the only way you can obtain a bullet made on these jackets is to buy bullets from a manufacturer who uses them.
Gerry,
Thanks for your input. I have no good explanation as to why it happends. I use .825" sierra jackets, and they are pretty much the same lenght as J4s after core seating. They just stretch alot less during pointing. Strange stuff! Its probably something with the difference in the jacket wall between the two.
Stay-moly, Bart's or Hines are all the same thing! Are they any good? Yes they are! Good enough to win the Super Shoot!
Gerry, J4's price was double of what it is now! If not for Hines I'm certain J4 wouldn't have slashed their prices.

DITTO that - well put, Bart!
Once upon a time, a dear uncle of mine and I were looking into drawing jackets - we, "chickened out"!
I had a cousin, who worked in a lab, up at the university, so, I talked him into an analysis of of J4 and Sierra jackets. Of the two different Lots of J4, his results proved to be: 92% copper/8% zinc; 90% copper/10% zinc;
two Lots of Sierra were both 95:5%. My understanding is that the Hines/Allied Precision Tool are supposedly the 95:5% alloy.
They all make excellent bullets. In my experience, the wall uniformity of the Hines jackets has been equal to exceptional J4 Lots - that is, <0.0002" wall-thickness variation. I confess to being anal about jacket "quality" - especially wall uniformity - George Ulrich (sorry, George - not!) always tells me I'm nutz!
I won't bore you with all of the [measurable] differences comparing the three - Wilbur, as usual, struck the nail soundly - acquire some of each, make some bullets a shoot them - then you'll know. RG
This is the issue that plagued J4 at one time. Lot to lot material differences were all over the place, wall thickness variation was usually pretty good. As we can see from the analysis, they were indeed quite a bit harder than the others. I haven't had any J4's in years, so don't have a clue if they still have these jacket material consistency issues. While I've seen less than stellar wall variation on some Sierra's, one of the best batches of bullets I've ever made were on one of those lots. Last year, I got a very good lot of Hines .820's from Bart, that not only run out great, but put little holes in the paper as well...
Make some bullets and shoot them. Sell all that measuring equipment and simply make some bullets.
