Hi All;
Currently I am experimenting with H110 behind a 240 grain Hornady XTP Mag bullet. Most of the official data uses longer barrels than my little 5", so comparing my velocities to printed velocities is an apples/oranges situation.
I was going to compare to factory ammo, but the only commercial loader that I know of to use the 240 gr. XTP Mag is Underwood, and they are notorious for hot loads. So even if I got a hold of some, it would probably be significantly faster than my loads, anyway.
So, I was wondering if anybody has chronographed the same .460 S&W Magnum loads out of both the 5" barrel and some longer barrel for velocity comparisons. If you have, what were your findings?
If not, what do you load in .460 Mag, and what are the velocities for your loads, and what barrel length do you use?
Thanks all for your responses!
Just for information's sake, here is the load data I have access to, as well as my own experimental loads (all using H110 and a Hornady XTP Mag loaded to a COAL of 2.160"):
Lyman: 10" barrel
43.5 gr. - 2246 fps
48.0 gr. - 2331 fps
Hornady: 8.375" barrel
41.0 gr. - 1600 fps
49.5 gr. - 1900 fps
Hodgdon: 10.743" barrel
45.0 gr. - 2084 fps
48.5 gr. - 2254 fps
My Data: 5" barrel
45.0 gr. - 1681 fps
48.5 gr. - 1755 fps
