The 7mm PRC is Here

[wind gypsy]

But is it a chamber spec issue or is it a FL die spec issue? I tend to believe it's more of an issue with how they spec'd the FL dies. It's kind of one of those chicken or the egg debates.

Regardless of who you choose to blame, the two don't seem to match one another like they should which causes the clickers.

My understanding is that even making tighter base dies doesn't always help it. With the PRC in particular the ADG brass is supposedly thick enough that you risk cracking dies if you make em much tighter.

My worst experience with clickers was with a 300 Norma mag. My dies would resize the web for plenty clearance but that Norma brass expanded very easily at the base upon firing and the bolt lift got very sticky, even with middle of the road loads. I know a lot of builders advise avoiding norma brass for 300 norma mags now because of that. I only used peterson brass briefly but it seemed to resist the issue better and I know a lot of folks advise using lapua brass. Has anyone had better luck with lapua PRC brass?

Maybe, but those 180 ELD-M's have been very hard to find for a long time and I've been looking. I was able to get a couple boxes of them from someone that had a few to spare. The BC, if actual, of those things is pretty impressive for a 180gr bullet. Probably why they're so scarce.

By my research, the last time they were available at a major retailer was October. Meanwhile, every component I need for 6s and 6.5s become available almost weekly.

I am excited for the 7mm prc . . . to neck up to 30 caliber in a tikka action. Lots of bullet room and thus more space available for powder in the case. Could possibly get as much powder in there as a 300 win mag and with possibly improved efficiency, great performance. No, it doesn't do anything the 300 win mag can't, but it does it sexier.

There is no clicker issue if you shoot factory. The majority of gun owners do not reload. They buy the rifle, scope, rings, bases, sling, and two boxes of ammo off the shelf and go shoot a paper plate group at 100 yards and call it good. Then go wound animals and not recover them.

if they are wounding stuff, they just need a bigger cartridge the 7 prc will be a practical graduation for the 6.5 prc wounders

The 7 PRC is the same SAAMI COAL as the 300 win mag: 3.34”. For a Tikka T3X you will have to replace the bottom metal to accept longer mags if you want to seat the bullet short.

No you won’t. That’s an issue with the 300 and 7 rem because the SAAMI coal wasn’t designed to load long bullets to the lands. The PRC is designed litterally for that reason, therefore it’ll be perfect in a factory tikka mag.

You can only get a cartridge in the T3X action that is shorter than 3.5 inches unless you modify the action. Even with a modification to the action, the max cartridge length is 3.6 inches. If you are shooting factory ammo then no worries. But if you are looking for an accuracy node to seat a heavier and longer bullet, you will probably need more than 3.4” which is close to factory mag length.

I’ve built 4 tikkas on long action mags. I understand the limitations better than most. The 7 PRC is the perfect parent case for all long action magnum tikka builds. The brass itself is much shorter than a 300 mag, there will be plenty of room to load a 7mm or 30 cal bullet long in a tikka mag. Not to mention if you’re going to build a 30-7PRC you’re going to have to have a gunsmith chamber it for you off of a dummy round anyways so chasing the lands certainly won’t be an issue.

Am i missing something here??
All this talk about the 7 prc being the perfect fit in a tikka, and wildcating a 30-7 prc to run with the 300 wm?
Do we have the actual case capacity yet cuz what I'm seeing is it's less than the 7 RM which is 83 grains.
The 300 wsm is 80 grains and the 300 WM is around 95 depending on brass.
If the capacity were in the mid 80s I'd be more excited but it sounds like it'll come in exactly the same as a wsm

Is this like another “____doodle” ?

The 300 WSM does not feed out of long action tikka mags without modification due to its slightly wider case.

No you are not missing anything...the 30 Nosler will fit the Tikka T3X action just fine and blow away the 300 win mag. Doing well with my Tikka in 300 Win mag though. Didn’t need to rebarrel as the Tikka SS barrel in 1:10” twist is accurate as hell with factory ammo. I have no clue why anyone would try to chase lands. For hunting I change bullets obviously. Seating depth will be different for each type of bullet I load.

I changed the bottom metal so I have enough real estate for up to 3.5” OAL. Since the Tikka shoots factory ammo so well, I don’t think the throat is very long but going to measure where jam is just to see what kind of jump I will be dealing with. I intend to work up some 200 gr plus loads this winter. But for this elk season, I will be shooting the 180 gr Accubonds in factory ammo which are shooting decent groups in my rifle. I don’t have any use for a 7 PRC, but if I did I would build off of a Defiant or an ARC Nucleus or some other custom action that I could twist on a custom barrel and not fuss with magazine length. It wouldn’t be a Tikka action.

I know I have 2 short mag tikka builds, mountain tactical magazines are a direct replacement and they're smoother than the plastic factory cheese

I’ve had 2/4 mountain tactical magazines not fit properly and have feeding issues. I’ve never had an issue with the factory mags and they’re lighter.

The 7 PRC > 7mm Rem Mag. I’m stoked for a truly modern 7mm!

Try the latest versions they're very light and don't have any feeding issues unlike my factory mags which hang up all the time.
They're specifically redesigned for wsms

Gila you're only considering saami coal, but you're not taking the case length into account. For 7 PRC with a long, heavy high BC bullet seated way out you will only be at 3.33. You're not going to be anywhere near 3.5.

 

[unclericco]

I’ve been waiting for the next wow cartridge to come along. This one looks promising and I love a 7mm. I’ll wait until someone starts making good brass for it and for rifle parts to be a little more available. I love my 6.5 PRC
