Home Forums Hunting & Shooting Ask The Gunwriters 7 Rem mag as good as it gets

m m - have you given the R M and Wby 7 mags CASES a close look ? They are pretty similar except for neck length.

YEP !!

I know that quite well. That's why I contrasted tippy top in one with easy in the other. On top of that the longer Weatherby throating allows for a bit more juice.

And the Wby has a higher pressure ceiling than the 7RM.

During my magnum phase you can bet I was up against it too. (Or maybe a little past it. )

I have two T3s in 7mm Rem Mag, they both sport Limbsavers.

Shot one just last week in the 98 degree heat.





Four shots into .527”, not bad. 3100 FPS mv.

This is a copy of my SILs 7mmRM but his scope is a Redfield 4x12. He likes it for when they drop down into this big bowl at the bottom of a pass, that's where the bulls are on Opening Day AM. You get "one AM hunt" before they all light out for the Wilderness Area about a mile away! ...I have "peered over into that bowl"...but don't hunt it...ain't no way I want a bull that bad! And they have to pack them out in pieces...at my bolted together 65yrs, I find I'm more of a "late season cow elk hunt" kinda guy, ha. He used the HSM 168 Berger ammo in his Tikka, very accurate.

Yep, there's SAAMI pressure and then there's "Fire" pressure...

Pressure variations noted while testing the 7RM resulted in a lower SAAMI limit, evidently not the case with the 7 Wby.

But, in the hands of an ambitious hand loader, not an issue...

I have owned several 7mm Rem Mags and all shot sub MOA. Back in the 90's I used 140gr ballistic tips and more recentlyTSX with very good results. I have always found the caliber to be very tolerable in the recoil department. With that being said, I have used a 7X57 the last couple of years. In my opinion, the 7mm bore is about perfect for deer.

Over time I've mellowed in my approach. Lately I rarely even load my 308's full throttle.

This^^^^^^^^

But the 7mag isn't new and cool.......

You hold a genuine "Fire" license to load'em to the hilt...

Don't leave anything on the table, go for the gusto...

DF

Seriously I've been shooting 139s at 3300 for many years -> -> -> with LONG case life.

IMO - with many firings above 5Xs and good cases -> -> you're NOT too hot pressure wise and that with several rifles.

7RM case capacity is pretty close to the 7 Wby.

So, if you run equal pressures, performance should be very similar.

DF

True, but the "effective capacity" of the Wby is a bit greater due to the effect of the freebore slowing the initial pressure rise. So with the same powder (say IMR7828 which is good in both), you'll burn more powder in the Wby to get the same peak pressure but you'll net more gas at that same pressure and so more work (manifesting in velocity) can be done.

It's amazing what you can do with 65-70K psi...

my daughter was raised in the country, bloodline Norweigan/Swede/German and at about 110 lbs. soak and wet was a cheerleader and a very pretty blonde sweety and now a doctor and she like`s using the 7 rem. mag. she said she never felt the kick or recoil when she shot deer but sure liked how the 7 Rem.mag knocked them down ! so boys if that little lady can handle a 7 Rem.mag. at full load what`s your excuse ? I also have a sniper friend who seen plenty real live action in many countries besides his Whitehouse duties,his favorite cartridge that he hunts big game a lot with is a 7 Rem. mag. and his gun also shoots 140 grain bullet 3400 fps with his handloads ,my sniper friend the only scope he likes is a Schmidt and Bender,he`s plenty fussy.

If I want to shoot 140 grain bullets, I'll use my 6.5x47 lapua. I use a SWFA scope though so I am not fussy.

How about on the 101'st round of a Saturday afternoon's fun shooting?

I could handle 101 shoots no problem even my son could, but can you Mathman ? And no Mathman we use are magnum rifles mostly to kill stuff with ,my family butcher`s,freeze`s and eat what we shoot for big game. Paper holes not that big of a deal anymore, besides this time of year its archery and trap/clay pigeons for me and my family. But next winter your free to join our winter money rifle shoots on Sundays and see how well you can do,we have had National 1000 yard bench champion join us before,yes his score was better than mine but mine was close. So let me know if you need dates ,times and directions to these winter money shoots any cartridge rifle is legal ,we shoot 100 to 500yards.
