I have a BUNCH of reloading books. Many of them older....
So there I was trying to see how fast I could get a 150 grain boat-tail to come out of my 300 Win Mag.
I pulled some 150 grain full metal jacketed bullets (boat-tails) from some old 30-06 ammo.
Then I looked thru every book I had and fopund two very hot loads for 4350. They did not say IMR or Hogdens in the old books....
One load was 78.4 grains and the otehr was 79 in and old Speer book.
Both those were about 4 grains more than any modern book. And for good reason.
I used Winchester virgin brass, Winchester Magnum primers and loaded them to 3.340 COL with a medium roll crimp.
I fired them from my Remington M-700 XCR tactical rifle with a 26 inch barrel.
The velocities were much faster than those listed in the old books.
I fired 10 shots. The top velocity was 3,612 and the bottom velocity was 3,580 fps. ... These babies were smoking right along......They shot a 1.1 inch group at 100 yards from sandbags. OK for pulled military FMJs.
The brass showed considerable pressure signs. Primer flow (cratering), very flat primers, some ejector marks on the case and lots of stretching...
So those guys who wrote those old books either loaded everything as hot as possible or maybe there were a couple mis-prints...
I will back it off a couple grains and try some premium boat-tails to see what happens.....
