I have heard about the "pressure spikes" with the 7 RM and find it hard to believe. I can't see that it is innately worse than any other similar cartridge. We never hear complaint about the 257 Wby, 264 Win, 270 Wby, 7 STW etc.
I remember when the 7 RM was introduced. Most of the early adopters used military 98 mauser actions and 1917 Enfields. At that time the M700 was considered only a slight step up from the 110 Savage. Neither were well loved. The rifles were built by all sorts of back yard gunsmiths and there were many different throat configurations on the reamers. Hardly anything was standard. Remember those old rifle are still out there being used with factory ammo. Today most agree that a 160 @ 3050 is about all you can get with a 24" barrel. I knew guys who would add powder until they got 3200-3250 and then quit. Those loads were HOT.
