28 nosler vs 7prc build. What are your thoughts?

[Slick8]

I have been wondering of a guy could chamber for 7rm, use a 1:8 twist barrel, use high bc bullets like the prc uses and get performance somewhere between the 7prc and 28 nos with appropriate hand loads. But I have zero reloading knowledge

You could easily out pace the PRC with a fast twist properly throated 7RM but you can't keep up with a 28 nosler without stomping hard on your brass.

I know the PRC was touted by the big H to be neck in neck with the RM but it ain't. IMO, it's more of a juiced up 7 saum.

You have to be careful with realities when reading the marketing hype of new cartridges. Back in the early 2000s the 7 and 300 short mags were marketed as ballastic twins of the 7rm and 300 Winny. The short mags are fantastic rounds but like I said above there's no replacement for displacement.

The heavy bullets and shooting past 600 are out of my wheelhouse.

No worries. I'm not looking to hunt past 600. Shooting steel will be a different story though.

Here's what it boils down to IMO, effective max range based on a minimum velocity threshold to ensure reliable expansion.

Let's use a 2000 FPS as a minimum. I know most bullets are good down to 1800 fps but I like a little margin of error. Additionally, when you reach that max range for a bullet, accurate ranging and dope becomes super critical. Lastly, these numbers are a really long ways out for factory ammo, IMO.

I set the base parameters at 5000 ASL, 45 deg and no wind. Again, just looking for a min threshold here.

The 7PRC with a MV of 2800 FPS which is a good known average drops to 2000 fps at 775 yards.
The 28 Nos with a MV of 3000 fps gets you to 950.

NOTE, I've not loaded the 28 Nos but have loaded a 30 Nos and loved it. IMO, It's about ideal for a 215-230 grain bullet. I used 3k as a safe margin in a 24 inch barrel and most powders. You'll likely need N570 to hit that 3100 FPS mark which is double hard on your barrel and only gets you and additional 75 yards effectively out to 1025.

Based on this, I'd say go 7PRC or step up to a 30 cal.
FWIW, I had this same mental maturational debate over the past few months and went 7PRC. Can't wait to get it here.

BTW, I'm like to ole 7.3 Powerstroke hands, no replacement for displacement.

I can relate with the 7.3 reference. Other than I swapped a 5.9 into my OBS a while back and it was the best thing I've ever done to that rig

Well either way, the prc and 7rm will (and has) turn any animal into meat for the freezer out to 600 yards.

Thanks everyone for all your help. Looks like I'm going 7prc!
