For those who like 7mms

In 1988 the Boss bought me a Remington 700 BDL Custom Deluxe in 7 mm Rem Mag. I've used it for hunting and plinking. Love shooting it with my handloads.

I'm a fan of the .275 Rigby, had a few Mausers chambered for it over the years.

Currently have a Bubba'd 1916 Spanish I'm working on.

I have a question for all of you 7mm shooters.
What is the heaviest bullet that is worth trying in my 7mm rem mag?
I believe that the twist is 1-9.5.
I have only used 139 grain to 154 grain.

Typically, 7mmRM shooters are using 160-175 class bullets as it has the case capacity to handle them well. It's been said that "Nosler created the 160 partition and God created the Elk for it."

I think of it this way:
7mm08: 120-150gr
280/280ai: 150-168gr
7mmRM: 160-175gr

All the above are dependent on twist rate in some bullet profiles (lengths)

The way you are using your 7mmRM with the 139's and 154's would diminish the 7mmRM's abilities over the 7mm08 and 280/280ai. It's the 7mmRM's additional case capacity that maintains performance as bullets with higher BC's and SD's gets pushed further and further into the case due to length.

This is very similar to the relationship between 308 Win, 30-06 and 300 Win Mag.

@WisBorn see my edit at the bottom of my post above, you liked the post right before I added the last comment.

I agree with your comments.
With the 308 win I used 165 grain, 30-06 150 & 165. 300 wm and 300 wsm 180 Partition and Accubond.

When I bought my 7rm I started with the 139 with its velocity gain then switched to 154 primarily for deer. I would like to find a heavier option for the bc gain of some of the newer bullets to shoot at longer range targets. If elk is on the menu Partition and Accubonds would be my first choices.

I shoot mostly heavy tipped target bullets, so the 162 eld-ms are my go to now that I've burned up my supply of 162A-max.
Ive not killed anything besides goats with the ELD-Ms, but I've shot a pile of game up to 1k+lb feral bulls with those 162s in both my 7mag, and 7STWs.
I started out with 139s also, then went to 120s, then to 154, and 162/168s.....burned out the barrel on my A-bolt with the A-maxs.

IMO for light game, the 120s are emphatic killers. You just need to get them INTO the boiler room. The 139s give you a little more penetration but act similarly.
The 154+ start to become do all bullets. They have enough mass that you can shoot soft bullets and expect exit wounds on most lighter game and presentations, while penetrating plenty far enough for behind the shoulder shots on even very large game.
If hunting for hard to penetrate or dangerous critters id switch to a Partition or Mono, but for nearly anything else im comfortable shooting 160 class cup n cores. If im unsure of the animal Id upgrade to bondeds or a partition as well.


All that being said, I also agree if your going to primarily shoot bullets lighter than 160gr might as well step down in capacity.
equally if your dead set on going above that, might want to step up on capacity. I used 175s for a while in my STW because I was afraid it would blow up the 162s at 3200.....It didn't, and everything I hit with them dropped on the spot. The 175s were clocking right at 3000 and didn't open up as quick, but also didn't provide any advantage, even on feral cows.

Agreeing with the above posts, I get excellent accuracy in my 7 mag with 160ish range bullets.

I have shot a lot of 139 gr bullets in my 7RM, also a lot of 160 gr. Both have worked very well for hunting. I have loaded and shot 175 gr. and was able to get good accuracy at the range. Never shot an animal with the 175s.

7x57 Mauser for me.
Great cartridge.

I think I'm going nuts.
Surfing the web looking for ammo.
Did a quick look at rifles. Found a left handed Savage 110 storm in 7 mm rem mag.

Do you need two 7 mags?
I have ammo to feed it!
Having a hard time finding the guns on the wish list now at normal prices and available!
