Hornady Light Mag
« on: January 08, 2005, 06:37:13 PM »
Has anyone tried the 7mm-08 Light Mag?

Shoot pretty well? Velocity might be a little hard to reach hand loading. 3000 FPS 139 grn bullet.

Thanks,

About the best I can get them to shoot in my R700 LSS Mtn. Rifle is 1/2" at 100 yards.  :eek: But then they never go over an inch at same distance.  :lol:

Really they are super accurate in most rifles and you'll not match their velocity at SAAMI pressures. My rifle prefers the original with the 139 grain SP to the newer SST but both are sub MOA in my rifle. It's the ONLY ammo I use for hunting in mine.

Thanks Greybeard!

I handload, but I don't think I can reach their velocity.

I think I might be able to with the 120 Grain Nosler. (3100 FPS)

Thanks again for your comments.

Now why is it the some of the fastest factory ammo velocities can't be achieved or exceeded by handloading?  I find it strange, but is it because of the propellants they use? Maybe a certain mixture of different ones?  What is it that makes factory loads the some of the hottest out there and still be safe in many rifles? :?

I think I'm gonna try Hornady's 139 gr. SST Light Mag ammo in my 280 Rem. Remington just came out with a 140 gr. "Premier AccuTip" in 280 rem. The problem with Remington is they never seem to keep "new" ammo around that long. They had a 140 gr. ballistic tip for the 280 Rem. them they stopped making it after a year or so. I had the same problem with my 223 Rem. I was using a "new" style of ammo it shot great, then a year after they came out with it they did away with it. Hornady seem to know what they want make and what they don't, they don't keep "coming and going"!

I don't "handload" myself so I'm not an authority on it by any means. I do however work in manufacturing (auto industry) and I know that "large companies" have the time and money for "research and development" and they all want to "out do" each other. Sometimes things get perfected to the point that there isn't anything more that can be done.

NY Hunter the 280 light magnums from Hornady shoot great out of my Rem 700 Mtn rifle and hornady does mix powders to get those velocities.

Ammo makers do not use the same cannister powders we reloaders do. They have access to powders we can't get and both Federal and Hornady use a special loading process in those extra velocity rounds they load that isn't available to us also. You won't match those velocities as SAAMI pressures.

Graybeard is right about the powders. Hornady uses extra-slow burning rate powders and with vibration and other patented processes manages to squeeze more of it into the case than you could ever do at home. This without crushing any grains either. The differance between a full case packed willy-nilly and a full case where the powder grains are stacked neatly like sardines in a can is why they can do it and we handloaders can't. :cry:  But, handloading can still tailor the load to the gun. :lol:
