Any rumors of a 7 PRC?

"Throat scorcher" Can we PLUZE get rid of this BS ? Maybe we need a sticky on NITRIDING ???

My smith has customers with P-dog town rapid fire 22-250s with 5000 down the pipe and no erosion !!!

The 28 SM is becoming quite popular and will run in the 3.750 mags. Very accurate and 195's will run up to 3200'.

I am confused. Which one is the 28 SM? So many competing 7mm long range cartridges!

It's the Sherman Magnum. It's a 300PRC necked to .284 essentially

What advantages would there be over the 28 nosler?

 

[WahooYahoo]

Less throat wear. That's huge in the Nosler. Maybe rich Sherman can add to that. I don't own one. I shoot the 7 Max

Wouldn't a 7 based on a 300prc case be a 7 LRM?

A 7 on a 6.5prc case would have the same performance as a 284, but be able to fit in a short action much better.

McWhorter has this.....it's called 7sprc, I said this when the 6.5prc came out and everyone was like, why, it won't work very good, there's better out there....ect. I thought it would be a good combination of speed and barrel life. So, someone made one and supposedly it's a hammer and a very accurate chambering.

I have a 7-300prc that's about complete at the smith now. Has a lot of freebore 0.240" will be shooting 170 Cayuga, 184hyb and 195 eol. Case capacity is about 95gr, will likely run Retumbo and 8133. And if speed is absolutely essential, I'll run N570 or RL33. Barrel is only 22" to run with my ultra7 supressor.

Awesome
Keep us updated on your load development
I'm really interested to hear about the 195's

I'll test them, but I've saw a lot of mixed results with that bullet. 184 hybrids and 171 Cayugas will be my main focus primarily.

Speed is a young buck's game.
7 LRM, though that horse has been flogged many times. It performs, though only a marginal improvement over 7RM.
Worth the cost? Absolutely.
Gunwerks may have a contract with Hornady that blocks them from a competing chambering in 7mm.

How much does it cost to nitride a barrel? Is it the vacuum furnace nitriding or cyanide salt bath?

 

[can1010]

control thermal in phoenix Arizona. the last couple I had done were in the 100 dollar range with shipping. it is the salt bath nitride. while it definitely helps with throat erosion it is not a cure for rapid fire or being crazy and way overheating the barrels

 

[P7M13]

There's a shop here that does the plasma nitriding. When I have time, I'll reach out and inquire about cost.

 

[twister]

are you doing full break in then nitride or on the chambered barrel or just the blank?
