Home Forums Hunting & Shooting Hunting Rifles 7mm PRC = 280 +P?

Yeah Scotty, it should cause a good bruise. Grins.

The thing is, all the urber-hype that came out on the 7PRC’s velocity caused some heads to scratch for some of us who are seeing speeds far below what would be expected based on published information…

Heck, me chasing fps numbers, just trying to get within 100fps of what the cartridge was alleged to do, left me with a few empty boxes of ammunition I otherwise wouldn’t have had to use if their speed numbers were more realistic.

It will kill, no question. And I will likely hunt it in a few weeks for a Roosevelt.

I’m actually more interested to see how the 175gr Eld-x performs into meat/bone at 400-600 yards. This is my first rodeo using this bullet on a game animal.

I haven't run mine over a chrony but I built it with a 22" barrel as a compromise as I will shoot it suppressed. Would be perfectly happy with 2,800 fps with 175s, easy to shoot, ammo becoming available and those high BC bullets get better as the distance increases. The older I get, the less I care about velocity, quite happy with any cartridge in the 2700-2900 fps range (my favorite 308 load lumbers along at 2700 and kills with authority). I was slow to get interested in the 7 PRC having use a 7mm RM for the last two decades but the more time I spend with it, the more I thinks it's the ideal elk/mule deer cartridge.

The change in the measured velocity of factory ammo and variations in powder is troublesome. The lower than stated velocities are troublesome. I'm not a velocity freak but I want something to do what it's supposed to do.

You should be able to assume you're going to get 250 fps over the 280AI with the PRC from reading published load data.

The PRC maybe a hot item now but the 7mm Mashburn did those velocity numbers 50 yrs ago with 300 Win brass as the source. Mine will consistantly shoot .6 in groups. So even though it may be a bigger 6,5 manbun they haven't done much but reinvent the wheel.

A lot of guys were telling y'all that the 7mm PRC is a stinkin pile of shyte, but did y'all listen ? Fk no ya didn't, some of ya slower ones defended it like it was the greatest invention to ever be dreamed up by mankind

based on case capacity alone ..... It won't do squat over what the 7mm WSM, 7mm Rem and WBY have been doing since the great flood

but hey !!!! It's so MODERN it's the bestester thing like 4eva !

I'm still laughing that so many bought the wHorenady Hype, even after all the 300 PRC bul lshit they dumped on the glazed eyed dimbulbs that call themselves gun loonies

from now on please just use loonies K ? lmao !

Other than that... the only time anything 7mm gets interesting is with 195-197 gr bullets at 3250-3300 fps

or faster

An "Old School" OEM Big Green 9" and small change 7mm RemMag will stabilize,Smooch and feed 180 ELD's at 2900FPS+. I've a few. Hint.

The 284 Prick wears a farrrrrrrrr shorter case length than the Mash',which simply equates to the advantages associated with MUCH better bullets. ESPECIALLY in things as fhuqking schitty,as Win Model 70's. Hint.

Many folks will simply find and do sensational things,with over the counter .796 BC's chambered same. Hint............

7 mm prc fans:

The more I monkey with 7mm's the better I like the .280 Rem, especially if you are using bullets in the 140-160 grain range.

Calm down Swamps. I didn’t buy Pom-poms or a cheerleaders outfit to go with the rifle.

🦫

Bullets matter wayyyyy more than headstamps and if it were 140-160gr or bust in .284" bore sizing and especially in a 280,I'd simply .697 BC in 264 Kreed at 2700fps from a 21" spout. Hint.............

I ain't the brightest and been drinking heavily. But sensing that the prc is a poor cartridge. I've fought against being a 7 mg fan for years but starting to think it may be all it's cracked up to be

My Rem mag will do just fine, no trouble getting 2950 with 175s. The Mashburn does even better, 3050 is a breeze with them. Brass for either is cheap and everywhere, any brand I want. I’m not a factory ammo guy and don’t really care for Hornady brass so I’ll leave the PRC to the other folks.

Ok beretzs, fire up the Jiffy Pop, buddy. Got to the range this morning.

24 inch Douglas premium stainless barrel, SAAMI chamber cut with 4D reamer. 137 shots before this morning. Cleaned bore.

60f degrees, 1,800ft elev.

Caldwell chronograph that has been consistent and predictable with many tiny standard deviation air rifle tunes. Posts same numbers as my buddy's for what that's worth. 15 feet from the muzzle.

Burleyboy, I pulled an ELD X from the Hornady load and it is the ball powder.

I was getting a stiff bolt with some of the Hornady ELD X load previously and so shot 3 of these early with a barely warm barrel and then 3 more at the end with a very hot barrel. I was thinking maybe the cartridges were heating up in the chamber effecting the powder. I did get some difficult bolt lift with the last three but, the numbers don't show a pressure spike. Maybe a brass thing?

My rifle LOVES the Federal 175 ELD X load and the Hornady 180 ELD M load. Puts all the tested loads under an inch but these two into well under an inch. And, the Fed X load and the Horn CX load shoot to the same POI at 100.

I was really only interested in the Federal load but, threw the others in for you guys. Honestly, I don't really care how fast it is and my main concern was what beretzs alluded to. I don't want it too fast for cup and cores to work well at 50 yards.

Pretty sure the math is right. Anywho:

Federal 175 ELD X (including 1st clean bore shot which seems to be an outlier)
Average of 15 shots 2,930 f/s
SD 18.2
ES 68

Federal 175 ELD X (not including 1st clean bore shot)
Average of 14 shots 2,927 f/s
SD 14.5
ES 46

Hornady 175 ELD X
Average of 6 shots 2,876 f/s

Hornady 160 CX
Average of 3 shots 2,904 f/s

Obviously,the 284 Prick will gain traction,as it simply connects alotta dots,for lotsa' folks. Hint.

I'd be VERY fhuqking impressed,if someone has more disdain for Hornie brass,than I. You gotta go Norma and fhuqking Peterson,to do worse. THAT is fhuqking impressive! Hint.(grin)

The Hornie .284" 175 ELD X stomps schit like 175 Nuzzler Partitions,but is just shy of .264 147 ELD M BC's. Hint.

I'd MUCH rather shoot the higher BC 180 in a lesser case,rather than suffer parachutes pushed faster,in a longer action,barrel,much more powder and less fhuqking FUN. Which is why the Mash' is a Goat Fhuqk. I shoot the 180 at 2800fps+ in multiple 7 Whizzum's. Hint.............

Stick... what brass you use in the WSM?

Wtf. Maybe I'm too drunk. Where are you on the prc bs? I was almost tempted to buy one.

I scored a rather good Lot of FGM 300 Whizzum brass. Bought a herd,so I could Hoard the Horde. Hint...............(grin)

BS can't handle anything better than the 7mm Rem Mag (recoil n stuff y'know)

so of course he's gagging on wHorenady's 7mm PRiCk, being that he's all Hornied & ELDseX'd up already as it is

I unfortunately do better than 2800 with a 168 using 57 grains of powder and a 22" barrel...grin....

It's a sound design,has support,but is early in the relative grand scheme of The Game. Hint.

I have LOTS of wares of the ilk,so I'm in a VERY different boat than most. Bullets matter more than anything and by a goodly margin,then such things as logistics and brass quality. I'd simply weigh accurately,the intent and purpose,then extrapolate in kind. Do you reload? Are you buying a Factory Rifle or going Custom? Heavy? Light? Medium perhaps? The more concise you can be,the easier it is to point the course. Hint.

In broad brushstrokes,the 284 Prick brings a pile driving ass to the table,over the counter. It stands largely alone there. Why? Bullets,bullets and bullets. Hint.............
