300 Norma mag. VS 300 PRC

[Ranger188]

Talk me into one or the other.
I do own a 300 NMI now, that would be a plus having the reloading
components for it, but not apposed to trying something new.
Going to be for 600yds. to a mile, in a chassis or stock for shooting paper
or steel only.
Do you find one easier to find loads for?
Slightly more accurate?

PRC 80% of the performance at 60% of the cost.

 

[ISS]

but, poster already has a NMI. What's the logic behind changing cartridges...?

 

[DaveTooley]

It was his question not mine. It going to require new everything regardless.

 

[moondog]

Plus, better barrel life on the PRC.

 

[Infrequent Shooter]

maybe the weight of chosen/planned bullet would help make the decision. You smarter guys can opine on this variable.

 

[Ranger188]

Sometimes just like to change things up.
200g -230 ish

Fwiw.....I have built a few 300PRC rifles. They seem to be very easy to make shoot small. Pretty efficient on powder.

300wsm? I have a 300nm, amazing how well it worked in the first 10 rounds.

 

[Ranger188]

I have one of those too, 300wsm.
In a BR setup.

300 NMI is definitely faster than the 300 PRC, but with good brass from ADG or Lapua, the PRC will pretty much run right along side the standard 300 Norma Mag for speed.

My 338-375 Ruger, based on the same 375 Ruger parent case as the PRC, will easily match and even outpace the 338 Norma Mag. Im only running 76gr of H4350 and getting 2980 fps with a 250gr Berger in a 26” barrel.

Thats also quite a bit faster than the listed data for a 338 Lapua using a 250gr bullet and I’m using 10+gr less powder.

Point being…The 375 Ruger case design used by the newer PRC family of cartridges is very fast, effective at long range and efficient with speed/powder ratios.

I think Alex Wheeler had a 300 PRC hunting rifle with 215gr Bergers rocking at 3100+ fps

What brass do you use? Necked up 300 PRC brass?

 

[FNSafari]

I guess the original poster will have to evaluate if giving up 20% of the performance vs the NM is worth it competitively.

I wouldn’t Change, the slight bit of extra case capacity helps with the heavies as does the case design, if anything I’d go 300NM improved just to minimize case growth.

Yes, i use 300 PRC brass from ADG. The shoulder on my 338-375R chamber design sits a little farther forward tho. Could probably do the same to improve the 300 PRC a bit.

Left: 375 Ruger case (Hornady)
Middle: Fired 338-375 Ruger (ADG)
Right: Virgin 300 PRC brass (ADG)

I'm shooting one. 300 NMI
Just get bored with the same thing, sometimes.
Have you shot a caliber that just does it for you?
Shoots really small and for a long time. Have had a couple that are just that.
Looking to find a big 30 cal. that does that for me.

Honestly, a big 338 cal will probably fit that need better. I love 30 cal and have a 300 NMI as well, running 220gr Berger at 3200 fps, but there’s still no 30 cal cartridge or bullet I’ve found that can compare to the terminal energy delivered by a big 338 Berger bullet hitting an animal when hunting. The big 33s are very impressive and just seem to hit so much harder at long range.

Even a slow 300 Berger thumps steel and critters with authority at distance.

For me the 7mm in a short magnum is still the most fun, hangs with my 338, shoots like my 6BRA.
