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

Who's got a reamer print drawn up?

How do y'all think the new standardized 7PRC from Hornady is going to fit in?

Way too big for F Class in my opinion (and others I know). It’s a considerably larger case and is probably excessive to target shooters needs. But who knows, I’m sure we will see some on the line at some point…

 

[Alex Wheeler]

I agree. It's for hunting not competition.

Not sure if this helps anyone but here’s my latest series on developing a 6.5-7mm variant this past month or so.

New Cartridge 7mm-3DP (based on 6.5 PRC brass) Load Development Part 1 (NOT 7 PRC)

New Cartridge 7mm-3DP (based on 6.5 PRC brass) Load Development Part 2 (NOT 7 PRC)

New Cartridge 7mm-3DP (based on 6.5 PRC brass) Load Development Part 3 at 1000yds (NOT 7 PRC)

Which inline seater are shooters using?

Which inline seater are shooters using?

I have bought a 7-08 Forster Micrometer seater which my gunsmith will run the reamer through for bullet seating...now if only I could get my hands on a barrel...

Which inline seater are shooters using?

You can use a 7 RSAUM Wilson in-line seater with minor modifications. The base-to-shoulder dimension on the PRC case is .030" longer. There are a number of ways to skin that cat, the easiest among them is searching for a stainless washer 1" OD 9/16" ID of the proper thickness (1/32" will do the trick) and drop it onto the seating die base. Before it occurred to me to try the washer solution, I chucked the seating die base into my benchtop lathe, chucked a 9/16" end mill into the tailstock and ran it in .031". The goal in any method is to provide dimensional relief in the immediate neighborhood of .030". The washer trick works just fine, it's inexpensive, and requires no material investment in time.

I think you could get a 6.5 PRC Forster Micro seater die and open up the center as needed and replace the seating stem with a 7mm, I did it with a .204 seater when I was building a 6x204. The guy at Forster was very helpful.

@F Class John

what is real barrel life?

@F Class John

what is real barrel life?

I honestly don’t know yet. I have three barrels and haven’t shot any of them out yet and two of them are over 1000rds.

@F Class John

what is real barrel life?

I should also say at Nationals I took 6th at mid-range using a barrel that started the match just under 1000rds at the time and brass that was on its 10th and 11th firing. That same barrel which was well over 1000 by the time long range came helped me take 16th place. Zero issues with loss of accuracy so far. We will see how long they shoot but I have a good feeling.

What do you use to seat the bullets?

See posts 49, 50 and 51 . . .

I'm using a 7mm RSAUM Wilson inline seater with a modified base, Works great.

A seating die made with the same reader you had your chamber made with.

Whatever the 7-6.5PRC is we need to get a standard design set up that is fire formed from 6.5PRC Lapua Brass across the board. I'd recommend a 35 Degree shoulder but honestly think it's going to be F-Class shooters who decide. I can dream up any diagram, but only the competition shooters will define a lasting Cartridge based on Brass life through development and capacity./just threw a fake in for grins "28-F" not PRC.

 

[Sandstorm]

I think they have it dialed in my friend..
we should know more in the near future im sure.

It only matters if you can get brass and primers. If not it is all academic.

I have not been able to get 30-06 Sprg., 284 Win, 6.5-284, 6CM, 6.5CM, 300 Win Mag, 338 Win Mag, 308 Win Match Grade or low grade, 6.5 Grendel, 45-70 Govt., 260 Rem, 35 Whelen, 8x57 Mauser, 6.5x57 or any other brass I need to reload for about 1.5 to 2 years now. What I have I got before that time. I have plenty of bullets and powder and I have plenty of Magnum primers. I am not buying any more powder or bullets until I can get more primers and brass.

Today I looked at over 30 different calibers of brass on Graff & Sons and all of them were out of stock!

Not doing any new builds in new cartridges or old which sucks for gunsmiths until I can get brass and primers. Not buying any new barrels either. Not traveling to compete either. If I can not enjoy my hobby no one else will profit from me either!

I thought about wishing, praying and hoping that all the guys hording brass and primers would burn in hell forever but then I took that back since it does not seem Christ like!

The hobby is disappearing because some of you are terrible human being and hoard. Stop it! The entire industry is being hurt because so many of you you old worthless humans are hoarding primers, brass, and ammo. No one needs to buy a new rifle if they can not get ammo and components! Few will compete if they can not afford ammo because you are driving up the price through hoarding!

Idiots have driven the new car and truck market prices into insanity! The repo market is now at an all time high and climbing due to it! How much is enough?

Rant over God Bless!

I understand the frustration of not finding what components you desire to buy, but if is simply not possible to buy up large quantities of products that have limited, or no availability.

By “hoarding” you imply that stashing personal supplies is interfering with the flow of components. The inability to buy Varget, for example is not because a few scores of guys have been allowed to each buy hundreds of pounds of it. No one’s phone comes with a “limit exemption” button. Most certainly, there are shooters with hundreds of pounds of choice powders, but they accumulated it over time when it was plentiful and when everyone else chose to keep their money, or should I say, hoard their money, probably to earn interest on it.

These people, I’m one of them, who buy for their own extended future use, which is arguably hoarding, when gluts are occurring especially, yes, but also throughout each year, in and out, - we don’t hurt the hobby, we actually moderate low demand cycles, reduce aging inventory, put cash in the hands of producers that we could enjoy elsewhere, and shorten the length of the lines you’re presently standing in for components, by not competing with your back orders in all the same lists you’re on or trying to get on. In fact, if we all had only a couple of months of components on hand, lines right now would be crushing.

The breadth of the choices in this hobby is not the result of guys spending a few hundred or a thousand dollars a year on only the “go to” “proven” recipe, getting their load perfect in 20 shots, and hitting a match once and again, with an eye to wind down their shooting just when their shelves go bare. There is a golden age of choices, still existing, benefiting all, because guys love this stuff passionately and make it a big part of their lives, deliberately, with excess to pass down when they are gone, in short, hoarders.
