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.

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.

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
