Best 7mm Rem Mag Load... I want your opinions

[jaridwulff]

Hi I am getting into reloading and am curious of some of people's successful loads out there. I am looking for other ideas to try out and am looking for a hunting round NOT a target round.

My first load I attempted consisted of:
-175 gr. Nosler Partitioner
-Federal Magnum Match Primer
-60 gr. of H-4831 powder
-OAL 3.35"

It seems to be working ok but am open to some other tries to improve the performance.

I am shooting from a Weatherby Vanguard series 1 rifle. I have read that the throat of weatherbys is longer and could cause some issues there if they are seated too low but the recommended length is 3.29" according to my Lyman book and I am a little over that. Can someone confirm this about weatherbys? Hope to hear from you guys, I don't post much on here and am hoping to get into the forums a little more now.

Thanks a lot. Keep your stick on the ice

They are refering to the weatherby cartridges, to help reduce pressure spikes. Nothing wrong with your current load but give a bit lighter bullet a go to take advantage of that cartridges velocity and trajectory. Lots to choose from, lots of guys will use a premium bullet in the 7 mag because of the higher velocity, they can be a bit hard on cheaper lighter bullets. Welcome to the forum

Probably 100 threads on this exact subject if you search the reloading forum

Don't worry about your rifle having the ridiculously long throat used with the Weatherby cartridges, Howa uses a much more reasonable throat with the 7mmremmag. I would try lighter bullets, to gain a flatter trajectory, with less recoil, and I would consider trying R-22, if you have access to some.

X2.
I bought my 7Mag for speed, not horsepower.
My load is 150 Nosler BT and 68g 7828 with a Win LRM primer for 3260 out of my Rem 798.

I use IMR4350 Win Mag Primers and Nosler 140 gr. Accubonds....Deer DONT like it.

160 gr Noslers over RL22 in every 7 RM I've owned or loaded for (and that's at least half a dozen or so). - dan

Dan what are your groups like typically? Best? Worst?

 

[FLSTFO2]

120g barnes ttsx over RL22, fast and flat. 3'' groups at 400yds

3/4"-1.1/4", depending on the rifle. Some needed a little tuning tio get their best efforts, but I've used this combo in 7 RM rifles from Ruger, Remington, Browning, Winchester, FN and Dubiel so far. I may have forgotten a couple others. - dan

168gr berger hunting vld and retumbo powder

160 gr. Nosler Accubonds, CCI 250 primers, and 65.5 gr. H4831SC at 3.290 COAL makes for 2980 fps and <1" groups in my savage 110. This load is over book max, don't go near that high without working up to it and watching for pressure signs. That said, book values seem to grossly under-load the 7RM.

160 grain Accubond, a caseful of 7828 and a 215M

just built some 7mm for a buddies Remington.
150gr CoreLokt over 64.1gr H4350 shot a .461(hole centers not outside edges) 3 shot group @ 100yds of the bench.
the factory Feds he brought with him were all over the place...
