This week while traveling thru Nebraska, I stopped in Grand Island and took a tour of the Hornady Plant. Needless to say -- but they are quite busy and expanding. They have doubled the size of the plant since last year. Got a tour where they make the bullets -- although not the "sensitive areas". If you ever get a chance -- worth while! I find it interesting that they can make such accurate ammo - on machines, no charge weighing, ect. -- and here we are micro managing our reloads with mixed results. They take tremendous pride in their work and quality control. I was always sold on them -- now so more than ever.
Talked a little with some folks about the 450. The tech I talked to said they get most inquiries regarding light bullets. He said to expect poor results with .451 bullets or less. Too much gas leakage around the bullet for consistant results. He suggeted the new 200 FXT for the 460 S&W Mag, using 2400 instead of any type of ball powder. Ignition should be better, an primers not as critical.
They did reinterate that their design is 38,500 psi and did hint/suggest that the SMR primers not only produce good accuracy --more so that large pistol or rifle -- but limit the amount of powder that can be burned.
For those of us that like a little heavier bullet, call them and tell them that you want to see the 300 gr. FXT packaged instead of having to buy them in Muzzleload packs.
