regardless of brand or action number i have a 300wm and can use either mag of 3.850 or 3.715 depending on which stock i use. now a list of current cartridges i have, then a possible list of choices (you can add other choices).
what i have currently
6.5prc
264wm
7saum
300wm
for possible change(s)
7rm
28nos
300prc
300wsm
not sure about any in
27cal
7prc
33cals
reason i wouldn't choose these
7prc, not enough gain over the 7saum
passing on the rum cases due to heavy per caliber bullets would be seated deep even when using 3.850 mags
what suggestions would you have that i could find reloading components in stock as that would be how i could make final decision(s)?
If 7RM is on the table, 7PRC should be as well. 7PRC=7RM without the belt. Nothing more, nothing less. But better brass available. ADG, Peterson, and Lapua announced their 7PRC brass is coming. Neither will run with a 28 Nos, but both will outlast the 28Nos barrel life expectancy. Either will outrun the 7SAUM. 7MAX? 7MEGA?
300PRC is in the same boat with the 300WM as the 7mm versions. Pretty identical, just without the belt. If you have a 300WM, unless you go with a faster twist, it will be a duplicate for all intents and purposes. 300WSM will be a little less, but they are a great option. Still plenty for elk-sized game.
A fast 25 would be interesting, I really like mine. .257Wby, some of the "short" action mags like 25SS, 25MAX, 25PRC (or PRC/SI), etc. Lighter recoiling, high BC bullets, fast and flat, and amazing deer/pronghorn/black bear size game crushers, but not too overkill for coyotes and other varmints/predators.
A .277" would be between the 6.5 and 7mm rounds. I think you have to be a .277 fan to bring those into play. There are some great bullets for .277s, however. 270Wby, 270WSM, 27 Nosler should all be considered if you go .277.
