Correction on the powder to AA#7 my older data shows 12.0 grains @ 1305 37,500 psi, this is also close to the product data for Item #9125 170 HP @ 1320 fps
I wouldn't mind having a couple of both weights for Chronograph tests. Does he have more?
How sure are you of the advertised and powder type? I thought this said #9 earlier?
Yes I had to make a correction based on review of more data, back then the powders looked so close but #7 had a more flatten ball/flakes, Also the Item Numbers show the product velocities on the back of a box...My older data for Accurate Arms Powders showed very similar specs so I added that info to the sheets also.
Another thing to keep in mind is that this ammo is older and newer lots of powder can behave a little differently!
Still trying to get the 155 gr cartridge to document also
Hornady Old Ammo
155 HP 1410 #912?
170 HP 1320 #9125
200 FMJ 1150 #9128
This looks different than mine!
Hi gents,
I'm another newcomer to the forum and I just wanted to applaud the excellent work you all do here. Interestingly enough, I was first drawn to this site because I was looking for some information on some ammunition I have that I've never been able to find anything out about: Hornady Frontier 155gr TC JHP (The exact product number is #9122). I noticed that you're still looking for some of it and I was wondering if I might be able to help out your cause and send you a few for a pull down?
Centimeter, Welcome to the forum and thanks for your consideration in helping with the documentation process...sent you a PM in case you want to continue your offer.
Thanks and best regards... :D
PM received, thanks!
