7mm PRC

[FEENIX]

If every dimension other than bore diameter is different, it's not the same case design.

Agreed!

Innovation is production or adoption, assimilation, and exploitation of a value-added novelty in economic and social spheres; renewal and enlargement of products, services, and markets; development of new methods of production; and the establishment of new management systems. It is both a process and an outcome (https://en.wikipedia.org/wiki/Innovation).

Hornady is leading the way in the cartridge and ammunition support industry and is an envy of their competitors. Their competitive advantage stems in part from their design engineering and marketing teams and their collaborative/partnership with other firearms and firearms related support entities. Perhaps the most successful is with Ruger and of course the CM (like it or no, support it or not, it is real) that catapulted a renewed interest in the shooting/hunting world and of course $ales/revenue$.

I for one is very thankful for anything new regardless of who comes up with it or however minute the difference is from the parent case or how similar it is from "x", as long as they also provide off the shelf support. Having choices is great, what we do with it is a personal matter/preference.

Cheers!

Well said FEENIX! Thanks for posting that.

As I see it and what I'm looking for personally is similar to what Nathan Foster lays out here: https://www.ballisticstudies.com/Knowledgebase/7mm+Practical.html I'd just add no belt and to use the modern design principles that the Creedmoor/PRC (love it or hate it, it's real as FEENIX pointed out above) and others use.

So, I here are some of the comparable (ish) options as well as the issues IMO. Some great cartridges here but if we are discussing options it's good to see what could be "improved". I'm sure I missed some and a lot of this is opinion only but...

• 7mm LRM - horrible brass at horrible prices, maybe a little long in the neck. With the 300 PRC brass out now and yet to come, this could be formed reasonably. Capacity/performance right there
• 7mm Blaser - Not as common in the US, decent brass but expensive and somewhat difficult to get, the improved version might be a little better with a few more grains capacity
• 7mm Practical - (similar to 7mm Mashburn and 7-300 Win Mag) ideal goal but done with a belt - so lose the belt, make it a little shorter fatter powder column but capacity right there
• 7mm Dakota - Non-standard head size, proprietary design, brass cost and availability lacking, slightly overbore
• 28 Nosler - Overbore, rebated rim, brass cost and availability
• 7mm STW - Overbore, belted case, too long with long bullets
• 7mm RUM - Way Overbore, rebated rim, length
• 7mm WSM - Short neck, rebated rim, not enough capacity
• 7mm SAUM - Rebated rim, not enough capacity
• 7mm Weatherby - Belt, Not a modern short powder column/shoulder/etc., needs a little capacity
• 7mm Rem Mag - Belt, Not a modern short powder column/shoulder/etc., needs a little capacity

I 100% agree with this. I said the same thing when the .300 PRC came out and when the 6.5 Creedmoor came out. Hornady is not reinventing the wheel on purpose, they are simply looking at all of the good and bad in a certain field of cartridges and making one that fits the bill, does what the others do, but with huge factory support and great SAAMI spec ammo, chambers, and reamer designs. The 7mm-300 PRC would fit right between the 7mm Rem Mag and 28 Nosler, similar to the 7mm-300 Win Mag. What it will do though is have a modern case that fits and feeds in modern long actions with modern bullets, has factory ammo and brass, factory rifles, and an awesome SAAMI spec reamer design from the get go. The problem with a lot of cartridges is they were never intended to be loaded with heavy for caliber bullets in a 3.7" Mag box. If the 7mm-300 PRC, like the .300 PRC and 6.5 Creedmoor, is designed around modern bullets and rifles, it will not need any special reamers with longer throats or the need for an extended Mag box to utilize the best available modern bullets. Life is so much simpler when you can just buy off the shelf components, dies, reamers, ammo, and even rifles without any hassle or anything special.

Well freakin said!

Boy, you're a picky one Goldilocks; it has to be just right! If a few more brass suppliers jump on board the 300 PRC bandwagon the 7/300 PRC might be perfect for what you're looking for.

 

[jpndave]

Yeah, a little picky I guess. I think the 7/300 PRC might be a little overbore and setting the shoulder back like in the drawing I posted would be ideal, IMO. With the 300 PRC brass necking down will be super easy for a wildcat. We'll see...

No judgement here! I've wasted a lot of time and money reinventing the performance of readily available chamberings. Sometimes, you can't settle for close enough.

 

[jpndave]

I have never been totally on board with the 6.5 Creedmoor. I have brought them in for others and have shot several. I see the appeal but just can't quite get there myself. The 6mm Creedmoor on the other hand is perfect for that case IMO. I have a BLR custom rifle in the works to be chambered for it as a takedown travel rifle. I'm excited about that one. I also have a chassis almost done in 6.5 PRC. The 7mm would be a nice larger hunting rifle to replace my 7 WSM. Just a little more pep to get 180s over 3000 comfortably, decent neck and no rebated rim.

How do you reload something that has the worst brass in the industry ? Or is this discussion all of factory ammo? 28 Nosler - ADG brass, 7-300 NM Lapua and Peterson brass, 7-300 win- unlimited brass, the list goes on. What are the true long range custom reloaders going to do? Wait 2 years for a comparable brass company to hopefully start making it? Velocity is not almost any different than a 7-300 win? Sweet spot on 195's is 28 Nos on the button at 3050-3080 right ?

I'm going to go out on a limb here and say you don't have much/any first hand experience with Hornady brass, specifically PRC brass. Please provide helpful information rather than turning this into yet ANOTHER Hornady bashing thread.

No I'm sorry if you take brass personally I wasn't trying to be rude. The only brass I have reloaded so far that was hornady was 338 Lapua and Grendel. It was just very inconsistent poor brass. I only get 5 or 6 reloads out of Norma brass as well that's why I'm moving away from it.

It's nothing personal about one specific brand of brass. It's getting frustrating hearing blanket statements about products from folks with limited first hand experience. Nobody can make a definitive claim about any brand of brass if they've only used samples from one lot #. I had a bad batch of Lapua 6mm BR brass but I won't claim that it's an inferior product based on that single experience.

I've never used much Hornady brass before, but how does their new stuff hold up? Specifically, how does the PRC last and perform? Thanks
