I know everyone has a opinion cause everyone is a expert. If you has to choose between 300 win mag, 300 wsm, or 28 Nosler in a bolt gun. Gun will primarily be a clear cut, crop field, shooting house gun. Want one that’s going to be the flattest shooting round . I know they have +- to all any personal use or preferences

I'm no expert I just sleep near a Holiday inn. Look at Hornady's .300 PRC. Then the .28 nosler.

I'd go with the 7mm.......28NOS all the way 😀

Lol true , I’ve looked at the 300 PRC and like it the best just can’t find it in a rifle that’s not $2,000

That 26 Nosler in the classifieds would be a goodun.
Those are really nice rifles.

28 Nosler. Easy choice and will shoot very high BC bullets faster than the others.

If you want something to shoot flatter than anything out to about 400 yards, a 257 Weatherby would be a great choice. It will still get it done beyond 400, but the trajectory and wind drift really become a factor because of the low BC bullets in that caliber compared to the others.

I'm looking into getting either a 257 Roy or 6.5-300. Simply because why the hell not.

To me,it would be more about platform than caliber, any of those would work thoughg I would lean 300 win mag just because of component availability and history. A lot more load info and such on the 300 Win.

From the ones you mentioned; I’d go with the 28nos. The numbers on that caliber are very impressive. I had a Cooper built in 28nos.

Other choices would be the 26nos or 257 Roy.

I just happen to have a 26nos for sale.

No one has said it.
6.5 Creedmoor.

Already have one of those lol

7mm mag or ultra mag if you want more zip. Never been crazy about the creedmoores and all that jazz but that's just me.

Win Mag all day, and 200gr. Accubonds..

Whichever gets the job done with ease using federal bluebox from walmart

Flat trajectory really doesn't matter as long as you know your caliber and have a good scope with some type of moa reticle you familiarize yourself to.

However if flat is what you want then,6.5 Remington magnum,6.5 creedmoor, 25-06,270,7mm Remington mag.,338 ultra mag

6.5 prc and save yourself a lot of shoulder punishment mauvilla.

There are plenty of good ballistic calculators out there. Play with them. You can change caliber and specific round. Pretty easy to see what's flat. Most will also give good info on energy and such. I do suggest that you also consider avail9, price, recoil, and what it actua6does when it hits a deer. Of course also consider what model gun you like and what its available in.

Ya I would tend to agree. 6MM , 6.5MM & 7MM is what's perfect for most.
Something between a 257Wby on the small end and a 7MM WBY Mag at the top end. 257WBY, 6.5-285, 26Nos 6.5-300Wby, 7MM Rem, 7MM WBY, 28Nos

Out of the three you listed I would do 28 nosler. But if I were building one myself I like the 6.5-284. Or I might go with the new hotness like 257 mentioned the 6.5 prc.
