7prc or 300 prc

Maggot · Tuesday at 6:09 PM

I know the recoil of the 300 is supposed to be more but less perceived. Got it.

I had a 7 PRC and with factory 180 ELD got it to a mile ok. Like a dumb ass I sold that rifle. Now I'm looking to get back PAST a mile. Recoil aside, I know the 300 is heavier but the 7 has slightly better ballistics. Will the heavier bullet/more powder keep the 300 stable further than the 7's slightly higher velocity at the mile? I dont have an absolute distance goal in mind, just wondering.

Any advice appreciated.

The ballistics will depend what bullet you run in each.
Neither will be more stable at any distance but the splash from the 30 cal will be easier to see at distance.

I understood that but the 7 generally, apples to apples, stays supersonic longer. Again, all else being as equal as possible will they perform similar at 2500 or will they both tail off due to falling velocity. I'm not looking for an exact, absolute, answer, just a general comparison.

Combine both; 7-300 PRC. Run your same 7 PRC bullets about 150-200 FPS faster. Better ballistics, less recoil than a 300 PRC. Same dies and readily available brass as a 300 PRC if you already have those. All you need is a bushing.

Or do a 28 Sherman Mag or 28 Nosler. Just get two barrels cut at a time. Barrel life is going to be the only drawback (7-800 rounds).

Came here to say this. The 7-300 PRC is what the 7 PRC should have been.

They will perform very similar at that distance. Similar BC bullet going similar speed.

Splash is a huge divider at ELR distances. Can't correct off what you can't see. 7 will be hard to see at that distance unless you have spectacular moon dust. Where I shoot normally it's really hard to spot a 7mm at 1500 Yards. When I go out to Wyoming it's relatively easy to see a 7mm at 2000 yards.

If you want a 7mm @diggler1833 has a point a 7-300 PRC is hard to beat ballistically. But to reiterate most people aren't shooting a 375 for the better ballistics, (it's not much better than a fast 30) it's for the splash at those distances.

If you are seriously about getting into ELR I'd suggest building with a Lapua bolt face.
7-300 Norma or 300 Norma, 300 Norma-Imp, That way when you decide you want/ need more splash it's easy to turn it into a 33 or 37 XC.
Then it's not the huge initial cost of building a CT and you can grow as you go.

33XC is also perfect for Light Gun ELR matches.

Theres a pretty decent deal on a 300 norma improved in the px right now.

Dude I don’t know if I suck or my targets are too small or my location is too windy but I can barely hit 1.25 MOA plates at 1800 (24” square hung as a diamond) & 2100 yards (30” circle) with my 375 Cheytac

I wouldn’t have a chance with any PRC where I shoot with me as shooter

Get bigger targets for those distances.

On a serious note I've shot my 300prc at 1900-2100 yards and it's tough, especially when you can't see splash. IMO once you get out past a mile and closer to 2000 yards one needs something bigger, like in the 338 department and up.

As @Taylorbok mentioned in post 7, the 33xc would be my thought. I've seen a few and talked to the guys that have them at some of the ELR matches I've attended. Got to shoot a couple of them that were used in Light Division and recoil is no big deal. Now, barrel life is a whole other subject. 300gr Bergers going 3100 do kick up some splash if you miss.

wi50 · 2025-09-17T21:48:02-0400

So I used up some used parts and put a 300 prc together several years back. Did it because 300 norma stuff wasn't available at the time, got a lot of it but I'll put the kids, friends, loaner gun on the 300 prc. That thing just plain hammers. Its been ran to 2600 yards with decent luck. Ive got a
284 also, not a 7prc but something super close for horsepower. Its outa spunk before the 300 prc is. The 300prc is the easy button from what I've seen. But its the internet so im sure someone who actually spent money knows more than this guy

All things being equal, but still not the best for beyond a mile unless you just want to play with hard shots.

vh20 · 2025-09-17T22:28:50-0400

Not to speak for him, but OP is not interested in anything requiring reloading, last I heard. So, he’s probably just interested in the two he asked about. Anything bigger (Lapua bolt face) and the cost of factory ammo is horrendous.

Ronws · 2025-09-18T07:32:07-0400

I happen to think that the type of bullet might make a better splash than others but that would be hard to see. As for the difference in diameter, I am not as convinced that would make a more visible dirt splash. 7.62 mm > 7 mm but not by much.

But yeah, either tune up the 7 PRC or go with the 7-300.

It going .338 Edge worth it? Maxing out the
.540 face?

IMO Yes that is a viable option if you've already got a .540 action.
I've got a 338 edge Tube that goes onto an existing action so I can take 2 rifles and shoot light gun and heavy gun.
