300 PRC update

[Milepost]

For someone that has never loaded them you are rather amusing. That was a rhetorical question but thanks for the answer lol. If someone is wanting a reamer made for then then I would hope they would buy a box of bullets to send out as a sample to their Smith rather than waste a company's time asking for a free bullet.

I have some Flatlines. I won't have time to make up a dummy round until probably Tuesday.

Thanks Dave! This would be good info before one spends $75 for some 198's just to find out they won't work for their combo.

Something I needed to do before ordering a special 300 PRC reamer with a shorter throat.

 

[PowerstrokeOBX]

I’m very interested as well. I can’t find ammo or brass right now or I’d do it.

I'm in the same situation. Hopefully, by mid next year there will be more.

Midway has 11 bags of 50ct brass in stock right now!! Going to go fast!!! I snagged two.

Edit:. Had 13 in stock when I ordered this am right when I got the notice. Sent out a few PMs to guys looking so hope they snagged some up.

 

[Forrest]

6 bags left I just bought 2 bags.

 

[MOUNTIC]

4 left. Hope some guys who really need it jumped on this.

Quick question for you Dave, what die set for .300 PRC have you had the best success with?

 

[DAVETOOLEY]

COAL with Flatline 198's

I can't touch the lands with the 198's. It would take a freebore length of .000" to have a chance of running through a mag. Not that I would with that bullet.

 

[DAVETOOLEY]

Quick question for you Dave, what die set for .300 PRC have you had the best success with?

I'm using Hornady dies I had made 5 years ago. Not sure if anyone else has started making them. I have two sets of 30's and one set of 338 left. Both bushing type FL dies.
I use a Hornady FL die and Wilson seater for my 1K BR rifle.

 

[Cowboy06]

Looking into this for my next match rifle to replace the 300win mag. We’re just about to get some brass and reamer in nz. I’ve been running AI mags with the 300wm. 208 eldm. Running at mag length the ballistic tips flattened under recoil in the mag. I have since shortened my col and improved the accuracy by making sure the bullet doesn’t touch the front of the mag when the case is pushed forward to the shoulder stop.
My question is to those who are using he PRC in a 300 wm magazine is how much play is there with the case against the shoulder stop ( as the case is a touch shorter) and how would this affect bullet col and projectile position in the case using the likes of the 208 eldm.

Interesting. That sucks.

Just curious, how much room do you have left in the magazine since you shortened the coal?

 

[RunninRebel]

So I have a 300wm in a chassis that takes 3.715in aics mags. Would it be possible/ realistic feed the 300 prc in a magazine that size? Any recommendations on more traditional stocks or chassis systems with a larger magazine?

COAL 3.730" with a 225 about .010" off.

The two factory Hornady options will not fit in that magazine you currently have. You would have to seat the 212 eldx 40 thou deeper. I'll have to look at my numbers when I get home.

The 212s will fit in the 3.775 mags. And both fit in the 3.850 mags.

Not sure what chassis's take what size mags with the bottom metals. I'm sure someone has a chart. If you were starting over, there would be no reason to not get a chassis with BM that takes the CIP mags.

 

[j741]

KRG Bravo Rem 700 long action takes the CiP length mags

 

[110len]

KRG Bravo with the Accurate Mag 3.850 is what I have been using for awhile now. Works great with plenty of room.

 

[verdugo60]

If anyone gets a line on brass please let me know. Even just 50 would be great to start for headspace, load development, etc. Thanks.

They have six left right now.

 

[verdugo60]

Damn, just saw this, out of stock. Probably from people here, lol. Thanks anyways though.

 

[jasent]

For those of you looking for better brass
I’m shooting a 338/375 ruger. I use 8x68s Norma or RWS brass and fire form it to my chamber. The head is a bit smaller so some actions may not be able to extract but with a sako/ m16 style extractor it works great! I hate the cow fire forming so I shoot cheap bullets to fire form. I neck up to 375 then down to 338 forming a false shoulder with a slight crush fit. It is much stronger than Hornady’s primer pockets. For the 300 prc you could prob just trim to 2.600 the neck down to 308. Left to right: Hornady 338/375, Norma 8x68 fireformed, 8x68 ready to fire form

I bought them

 

[Forrest]

Midsouth shooters just shipped me 4 boxes of 300 prc brass i had backordered. I tried putting 20 boxes in the cart and it let me. So there must be more available.

The lot of Hornady brass I have is not the best - having concentricity issues. Have another lot coming in to try. We'll see if any other vendors start producing.

Yeah yeah motherfuckers.

So did I read the initial (and limited) information on the 300 PRC correctly:

Not belted
Same/more at distance energy on target than 338LM but less than 300 Norma
Slightly better ballistics than 338LM but slightly less than 300 Norma
Significantly less recoil than 338LM/300 Norma/300 WinMag

And....normal mag boltface

Of course Sherman already made an Improved version which will all but negate the ballistic advantage of the 300NM I'd imagine

How is that possible? Is the PRC creating new laws of physics or marketing is taking over common sense?

 

[b6graham]

Winmag? Eh no

But less powder less recoil. Especially with a lighter bullet

 

[jasent]

More powder and more recoil not less

 

[nick338]

I would love to know in what ways it outperformed the 300 Norma

 

[TheGerman]

That's why I'm asking. I don't have some fucking calculator that will figure out mundane bullshit like some of you quikload nerds do.

From the 2 places I read about the PRC, it was mentioned it had less recoil but didn't really mention, compared to what. Seeing as how they all group the 338LM, 300 Norma and 300 PRC together, it would make sense that's what they were referring to.

This guy has actually shot it:

https://gununiversity.com/300-prc-ballistics-and-comparisons/

'Enter the 300 PRC. As you can see from the chart below, it has better energy on target and drops less than the 338 Lapua Mag past 1,000 yards and it recoils a LOT less.'

'Also note that although the 300 Norma out performs the 300 PRC, it’s not by much. I’ll take the 300 PRC any day over the 300 Norma. Not how the 300 PRC (red line) is in-between the 338 Lapua (green line) and the 300 Norma (blue line) in performance (and is slightly closer to the 300 Norma).

It does all this in a smaller and lighter recoiling package.'

 

[schmi015]

Well to compare just Hornady ammo from a 24inch barrel the 300 norma and prc both launch a 225eld for their factory ammo. So...300norma 1st.

and 300 prc.

 

[jasent]

Sure if you compare 338lm with 250gr. 300gr is where the Lapua shines
For the record I thought you were comparing it to 300wm

 

[LastShot300]

I would love to know in what ways it outperformed the 300 Norma

Me too! or an honest comparison to the .300Win with the same bullet, same barrel length,...I cannot see how this puppy is so much "better"

Holy cow Batman! one of the most biased BS I've ever read about a new cartridge.

Guys, physics remains the same which is reassuring for most of us.

Talking about nerdy things http://www.shooterscalculator.com/recoil-calculator.php

Don't make me quote Forrest Gump on what stupid is.

 

[schmi015]

The closest comparison form Hornady that you can reasonably get with their published info is a 212 eld-x in 300prc and a 200 eld-x in 300 wm. PRC:

and 300wm with 200eld-x.

 

[Blaster7Romeo]

Well another thing is... the army would not have to buy new bolts to convert there existing 300wm to 300prc just a barrel..

 

[verdugo60]

Bingo. As long as the 300 win mags they have (m24's?) Can use a CIP length mag, which the PRC requires.

 

[Ledzep]

Who was/is making 300 Norma ammo for the military?

 

[Milepost]

Well another thing is... the army would not have to buy new bolts to convert there existing 300wm to 300prc just a barrel..

Yeah, but the older 338 LM can be easily converted to 300 NM too....!

Didn't we all see this kinda media hyperbole crap when the the 30 Nosler came out a few years ago??

Rule number one.... There is no replacement for displacement!! The Norma Wins...

Rule number two.... See rule #1.

Look, I really like the the 300 PRC as it is a nice compromise and should be an efficient, fast and easy cartridge to reload. It offers a minimal improvement over the 300WM and gets rid of the belt and uses a longer neck. It is just a saami approved version of a older well thought out wildcat and nothing earth shattering.
