7-6.5 PRC F-CLASS !!!!!!!!!!

[kev77]

Will the 7-6.5 PRC over come the 284 in fclass??? What's your thoughts

 

[NZ_Fclass]

Well, if good brass is available, and it's as easy to tune as the 7mm SAUM, who knows?

 

[B23]

Do you think the ease of getting top shelf brass for the 284 vs there's good brass available for the PRC with ADG and Lapua making it but it's not so easy to acquire have any affect on it?

 

[darkangel_r2]

It should duplicate shehane performance but with a stronger case head, shorter oal, and a longer neck. Sounds like a recipe for success.

 

[Alex Wheeler]

Yep.

 

[kev77]

Alex, how's it working out so far?? What powders seem to be working best?? 180hyb I presume.

 

[Alex Wheeler]

When a new cartridge comes along theres a learning curve. Even with the BRA from the Dasher. Very similar cases but 15 years of Dasher experiance goes a long way. So this will be the same way. Im confident that its a better case but it will take a couple years for the data and experiance to catch up. The 284 has been used for a long time and is the easy button for now. The prc case uses the same powders and bullets. Its very close. Which was the point.

I agree. That being said, where can I get a reamer and a set of dies??

 

[Alex Wheeler]

I order my reamers from JGS. Dies are simple. Bullet Central 6.5 prc die opened up with a 7mm bushing in it and a wilson blank reamed with the chamber reamer. As it catches on Id bet BC will offer a 7 and 30 prc die.

With the 6.5 PRC being based on the 300 RCM case, itself a shortened 375 Ruger case, it should sit volume & velocity wise between the 284 Win & 7mm SAUM & WSM.

I had long thought of doing a 7mm RCM.

Mag bolt face, not easy change from 284. Way more 308 bolt face bolts in existence.

I don’t think guys shooting competition are going to get hung up on a bolt face difference. They’ll just buy a new bolt from their chosen action manufacturer or have a whole new action/rifle made. Just my thoughts. I think the 7-6.5 PRC will be a great cartridge.

Which will be, a "Better" 1,000 yard round,.. the 7mm PRC or, 7 SAUM ??

IMO the PRC. The 7 saum is approaching too big for a competition round. I think you will find that its a little more touchy on the tune than a 284 and barrel life drops off quite a bit. The PRC will be closer to a 284. The reason I didnt improve the PRC case is to keep it closer to the 284 in capacity. But only time will tell.

If you're using 4350 class powders I doubt a AI version would give you much more anyway since you are already a long way from compressed with that powder class. In fact it may reduce its effectiveness with 4350 due to lower case fill percent. 4831 class powders would likely see a more noticeable benefit and actually make that a pretty juiced round.

I think an AI version might lose some flexibility and be put too solidly in 4831 class powders for a 180. It might give access to the faster end of h1000 class powders with 190+ pills though.

I think it also depends where you shoot, and it's country specific. The fact you have unlimited sighters and generally shoot 20 shot strings in the US makes sense why the 284 and this variant of the PRC would be more effective than a 7 SAUM. In Australia it's a different story as we get 2 sighters and then it's down to business, with most of our strings being 2+10, or 2+15. For this reason the 7SAUM rules here, with energy limit restrictions in most states ruling out the 300WSM. The 7SAUM can run the 180gr class bullets at a comfortable 2950fps which keeps it under our energy limit restrictions. The 284 is certainly very popular, but at our state and national level matches, if you're not running a 7SAUM, then you're probably not going to win.

The 6.5-7 PRC intrigues me, and if I did one I'd be making it an AI version and this thread has sparked my interest. I just need to decide whether to go down the path of a custom reamer and dies.

What about RL-17 in the ACKLEY version???? I use RL-17 in my 284 for 100 fps more velocity

It’s not very temp stable, so for F-Class with 15-20 shot strings plus sighters it can have velocity swings when the barrel starts getting hot. Also, the tune can come in and out depending on the conditions over the course of a few days. For a hunting rifle it works good if you understand the velocity change with temperature.

 

[Alex Wheeler]

As a rule of thumb, the smallest case that will get you to an accuracy node without a "speed" powder will agg best.

So the PRC sits around about the Shehane, KMR and 7mm Walker?
