Federal chart is very nice. Plain to see the obvious choice is a 270 WSM or 300 WSM. The 300 Win Mag is ok but not quite a 300 WSM. If you had the choice why not a WSM? The plain 270 is not even in the running.
270 not in the running? Hmm I know a lot of people that use a 270 win on deer and Elk ..i guess they need to go to their freezers and tell the elk and deer that they are not really dead.
You can get 3100+ out of a 300 win mag with a 26" barrel in real life, you'll have a heavier rifle and a little more push..your hard pressed to get 2960 with a 300WSM and maybe on a great day with the right load you can get 3000 but I haven't yet , so yes it is more then a WSM and less if you buy factory ammo...I have had/have a model 70,Abolt,Weatherby Vanguard,Vanguard SUBMOA and a Sako 75 in 300 wsm. I have had a Weatherby VAnguard in 270 WSM and a Model 70 in 7WSM. All handloaded for .. the most impressive was the 7wsm followed by the 300 wsm...in real life the 270 WInin the right rifle(24" barrel) will almost match the 270wsm with a lot less hassle and 1/2 the price on ammo. If you want a real step up go to a 270 Weatherby. The federal guide is that only a guide since they tend to load down ammo in a lot of cases. The Remington guide is a waste of time.
I like the weight of the Short Trac and my old BAR 300 Win Mag would jam if was was real cold. Besides it was heavy. I would imagine the accuracy is similar.
Thats because the BAR was made of Steel and has a real walnut stock on it. If one jams it is user error plain and simple. I have never experienced a jam on 1/2 dozen of the things in all kinds of nasty weather.
