28n, 7rum, 7stw decisions (7rm falls far behind)

[ARlife4me]

going by 3 choices, which could possible have longer throat life to give you more rounds before replacing the consumable? i know it varies, but would all give within the same amount of rounds?

i like the 28n due to case being shorter when using cip mags (3.850) to seat bullet out further.

the 7rum (to me) has a slight disadvantage over the 7stw as capacity being the culprit (not necessarily a bad thing)

7stw having close to the same case volume as the 28n has me on the possible choice?

those who has shot 1 or more of these cartridges weigh in your experience(s).

wouldn't all 3 be a "barrel burner" of less than 1k or 800 rounds? i don't want to try and get a 4"+ mag necessarily as action work will be needed(?). just trying to decide on or if i would add another 7 to my only 2 i have so far (7-08rem & 7saum). the 7rm doesn't give much more power than the 7saum is why the inquiry.

I personally like the 28 Nosler, and have one. The saami spec chamber is pretty good, and as long as you are not hindered by a short magazine (mine allows 3.65" or slightly over) then you can take advantage of the saami spec chamber.

In my opinion, the only drawback to the 28N is the case capacity. It's almost too much for certain powders, such as Retumbo for example, when shooting heavy bullets. Heavy projectiles need a slower burning powder to get max velocity and fill the case up.

I consider all of the three you listed as barrel burners. However, mine shoots really well with 166 A-Tips and 175 VLD's.

I wouldn't do an STW unless you have brass.

Kinda what drives my decisions is finding necessary reloading components before deciding on chamberings.

(7-08rem & 7saum)

Those are both great cartridges. A friend's dad shoots a 7 SAUM, has taken game up to about 400 lbs. But the 7-08 will do it also, IMO.

I would consider the 300 WSM also.

I have 30cals in 300bo, 308win and 300wm, so I'm good on 30's. Might do a 300saum rather than the wsm as it would be in another ar. Just trying to find a larger 28cal that'll add 200fps+ over the 7saum. I'd like to do a switch barrel/lug type 1 day. Trying to decide on a Barrett mrad as switching barrels would be easy. Finding out mag lengths before going that direction has been difficult. Using the long action for short mags would be an easy button.
