Re: 7mm Rem. Mag. vs. 7mm Weatherby

I've considered the freebore issue. I also thought that I saw the 7mm Remington was loaded to lower pressures. I'm having Kirby build me a 7mm but I hadn't fully decided on which one yet. This one is going to be a light weight pack rifle so I really didn't want to step up to the 7 RUM. I just priced 7mm Dakota Brass and don't really want to go that route either. I'd already pretty much settled on the 7 RM but thought if the 7mm Weatherby offered a lot more, I would consider it.

Re: 7mm Rem. Mag. vs. 7mm Weatherby

I have shot many 7mm wby's for 35 years. They are faster than the 7mm rem mag but not 200 fps. Closer to 100. Freebore rifles are very accurate. I have several wby's that will shoot 1-2" groups at 400 yards. If you are building one I would do the 7mm stw. Wby brass now is just way to expensive. I think the 7mm wsm, 280 AI, 7mm jrs or 7mm gibbs are better choices near the 7mm rem mag velocity range if that is the class you are looking for. If you want a magnum the stw is the one.

This is what I was inclined to say, but I didn't have the experience reloading with the 7mm Weatherby Mag. The 100 fps advantage of the Wthby over the Rem Mag sounds closer to reality. I've got two 7mm Rem Mags and two 280 RCBS Improved - 30 degree shoulders. My Rem Mag gets ~125fps additional velocity with the same 168 Berger VLD bullets. I'd get the Rem Mag before I'd get the Weatherby. If I demanded more MV than the Rem Mag provided, I'd get the STW too - simply based on LTLR's recommendation. He's shot'em all.

Re: 7mm Rem. Mag. vs. 7mm Weatherby

I've had both, I believe the Weatherby stats are based on a 26 in BBL and the Rem is on a 24 in BBl. Other than cost there was no real difference in the field.

Re: 7mm Rem. Mag. vs. 7mm Weatherby

I've had experience with both too. In my tests, the Weatherby/Norma case has a capacity of between 2 and 4.5 grains more powder than the Remington. This is measuring the volume of fired cases filled to the top of the case mouth. The capacity of the 7mm Rem Mag varies from brand of case. Certainly different rifles or chambers will cause a slight variation in the measured capacity of a fired case.

I agree with those who are skeptical of the 200 fps advantage. In barrels of the same length with maximum loads they are really very similar. The STW is a step above either.

Very good post.

Weatherby brass is just way too expensive to justify.

The 7mmSTW case is also far superior as it about equals the 300 Weatherby in case capacity.

Re: 7mm Rem. Mag. vs. 7mm Weatherby

Well it looks like the 7RM will fill the bill. If I need to reach further, I have my Edge. This will be my 600-800 yd. rifle and it will be light. Thanks for all the input.
