Jekyll and Hyde - the 7mm Remington Magnum

Iam developing loads now for a new T3X 7rm using 60.0 IMR 4831 with the 175 Hornady Interlock flat base , getting consistent 1” groups. Will need to try tweeting the charge and playing with O.A.L to see if it will tighten up.
 
My long range target rifle is a 7mm 700 Long Range, main load is H4831, 162 ELD-M at 3000fps. 2nd load is with the 171 Barnes Burners at 2950fps. Both are pretty mild loads to be honest, but I'm after consistency and that seems to be where it's at in this rifle.
 
I remember loading the 162 Hornady over 79grs of H870 many years ago. Shot amazing out of a A-Bolt and broke 3000fps easily. Factory ammo is so anemic.
 
I also used to shoot the 162 gr Hornady out of my Abolt. Now, most of my 7mag loads see a 140 TTSX at 3250 with RL22. The recoil seems a bit less and it's performance on deer to moose has always been great.

Be careful, if you shoot them too fast they’ll just pencil through!;)

Or as I was told by a sage old timer in a gun store when I was looking to buy a 7mmRM: "No, we don't have any Model 70 Extreme Weathers, and you don't want that cartridge anyway, the bullet yaws all over the place and doesn't stabilize till at least 300 yards. Here, what you want is one of these....." and then hands me a Tikka T3 Lite in 30-06. That more or less ended any inclination I had to actually listen to any of the remaining words coming out of his mouth, I pretended to look over the rifle for a bit to appease him, handed it back and left.

I swear most gun counter guys get paid an extra dollar to sell '06's and 300wm's :bangHead:

7mm RM was my first rifle, so kinda attached to it. Since have a 280 and a 7-08 as well. Prefer it to the 30's by a ways
 
My Nosler Model 48 Liberty is chambered in 7mm rem mag, and I couldn't be happier with the results. Great cartridge. I use Nosler trophy grade 140gr and the stuff rocks. Haven't gotten into reloading...yet.
 
I shot a 7mm Weatherby Rem 700 Classic rifle for years while hunting and it killed everything I shot,

I always used the Weatherby factory 160gr Nosler Partition ammo, advertised velocity 3200fps....then bartell convinced me to buy a Labradar........WeatherbyFan was devastated/embarrased :redface:...........when he learned he was only getting 2950fps out of that rifle :confused: oh well the deer died just the same !

I get 2900 fps out of my 280AI with 59.0grs of R26 and 160gr AB so far the deer don't seem to live when shot with this rifle either.
 
Interesting velocity numbers. I sometimes wonder how much discussion is wasted on the "difference" between cartridges like the .308 vs .30-06, or 7mm magnum vs similar cartridges like my 7x64 ( or other peoples .280 Rem) . I have had no trouble developing safe, effective loads for three different 7x64 rifles using a variety of 160 gr. bullets at 2850 fps. So in effect I'm shooting a 7mm mag, but some folks don't think the lowly 7x64 is "enough" for open country hunting or game bigger than deer. I think the 7mm Rem magnum is a great cartridge, but factory loads are quite often not quite up to "spec" ... Not that it actually matters much to game animals.

Well, yes, but every 7 mag I've loaded for will push those same 160 gr bullets at 3000 fps, give or take. couple hundred fps won't matter to the animal, but it does lessen bullet drop and adds to your effective range. - dan
