What is the experience or opinions on a CF barrel vs aggressive fluted steel barrel in the same length , in a this cartridge.

I understand CF vs Steel overall but curious if anyone had specific experience with both from the same barrel manufacturer.

I'm leaning steel with fluting due to its ability to cool down better when you want to go out and shoot more then 3 rounds in 30 minutes at some steel.

I’ve completely abandoned carbon for good stainless barrels and couldn’t be happier. I don’t like flutes personally so I just go with a lighter contour for weight savings. The only issue with long strings is mirage
I routinely shoot long strings with sporter weight barrels

I was once a carbon proponent, and then a steel proponent. And now, I just don’t think it really even matters. Especially for hunting. After being around guys properly building guns with both carbon and steel barrels, I don’t think you can shoot the difference most of the time. One of the best groups I ever shot was very recently was on a carbon barreled 28 Nosler. 5 straight shots of 180 ELDM’s with N570 landed into .2 MOA at 150 yards.

So now I’m kind of just, whatever you can find and whatever suites your fancy type of thing.

My steel Brux barrels have absolutely hammered with no effort at all. I really like that about them. But there are so many options out there that I’m sure could produce similar results.

all fair points!

FedEx dropped the ball today. No explanation of missed scheduled delivery. Just changed the date to Friday. That was a driver sticking it to the man and getting some extra holiday down time. Not sure if anyone will be around Friday to sign. I won't.

Generel numbers here, but with all the load development we have done, I am close. Carbon barrels are fussier than steel barrels when seen in large numbers. If we took one hundred carbon barrels, 8-10 would not shoot, while one hundred steel barrels, 1- 2 would not shoot. I like 2% odds over 10% odds.

I bet that pretty close. And spiral fluting the steel can be dicey as well as I just found at. Had a barrel with horizontal scaring across all the lands for a decent length up near the muzzle. And I believe it’s from an internal device holding it concentric and slipping during the fluting process.

If I had to bet on sheer precision guaranteed. Untampered steel barrel all day. But lately I’ve just seen a pile of stupid precise carbons that has me not so on the fence anymore.

100% I have stopped fluting my barrels and dropped a couple of contours.

 

[MT_Wyatt]

I’ve got a c6 sendero I really like for 7 PRC, but my #3 ace done for 6PRC is actually heavier, but a ton. The light or taperless contours seem like the way. Not really a fan of the spiral fluting either.

What brand carbon barrels?

 

[wind gypsy]

There was a time when I thought I needed 0.725” dia muzzle for 5/8 threads and the only way to get there and not be heavier than I wanted was carbon or heavy fluting. There are enough alternatives now that I think fluting and carbon are a waste of money and more negative than positive.

Doesn’t seem to matter.

Tried this cartridge out yesterday, results below.

TMK vs. Eld-M vs. Berger Elite Hunter terminal ballistics

We’ve killed probably 25 mule deer/whitetail/blacktail deer with my 6 creed and 108 elite hunters. Every single one was dead within 60 yards max. They all expanded well and did the same thing every single time. I really cannot ask for anything better. Still using the 108 elite hunters? Trying...

Deer down pretty quick but was thinking about 180s out of my 7 PRC on the way out….granted likely wouldn’t be so easy to send 3 down range as quick as I did yesterday?

What do you believe the 7 PRC is going to get you?

 

[MT_Wyatt]

What do you believe the 7 PRC is going to get you?

More recoil, slower follow ups, more/deeper damage. Certainly don’t need the extended expansion range it provides.

Based on what I saw, I don’t really need a larger total dia wound…the 175 ELDX honestly didn’t seem that much larger in total diameter but punched a bigger hole through both sides with the retained mass/base of bullet. Not sure that’s “necessary” though.

First smaller caliber kill, and old habits die hard but it’s apparent those 108s can put some hurt on.

Interestingly enough I hunted with a friend who put a 180 TTSX through a hind quarter and cut the femoral artery, super quick kill in a dynamic situation. Physical wound wasn’t huge. Made me curious what a heavy for caliber frangible 6 might do in a similar situation (he was shooting till it was down, bull was bailing).

That’s a bullet selection determined thing. Bergers ares going to give you exits reliably- others will. If you want deeper and still wide wounds, the 115gr Nosering DTAC’s will do that.

Very few do.

Again that’s mostly bullet selection. It isn’t hard to find bullet that behaves similarly to the 180gr ELD-M in tissue; as the 180gr ELD-M isn’t optimized (maximized) in 7mm for wound channel size.

They all kill and the 7PRC is a great cartridge. As for follow-up shots, etc., after a lot of animals and tracking it with a bunch of shooters, when people shoot until animals are down- the amount of rounds per cartridge/caliber tracks with how many rounds that person can hit within 10-15 seconds as that’s how long the average animals stays conscious.

Kill very quickly, and damage a lot of meat.

This whole discussion is very helpful, thanks!

I meant to write- “Bergers are not going to give you exits reliably”.

Also, Hornady 6mm 105gr HPBT will exit usually, and produces good wounds.

I shot a buck bedded, frontal with a 6 PRC and 108 ELDM's at 200 yards. It dropped him on the spot, and then about 5-10 seconds later he awoke, made it to his feet and stumbled down the hill out of sight, which only ended up being about 10 yards. He was still blinking and gasping for air about 2 minutes later when I got to him. I just walked away from him for a few minutes so he could die in peace. No reason to hit him again at point blank. It killed him though. Nice little wound channel and I wouldn't hesitate to shoot another deer with it.

But I made the same exact shot with a 300 NMI and the buck never awoke to take another breath. Both bucks were slight quartering and both shots were identical distance and placement (in between neck and shoulder). I didn't even hit the shoulder on the 300 NMI buck (bullet passed inside of it) and the scapula was busted into pieces. There was a pretty good difference between the two identical circumstance kills in my eyes. Both wound up with a buck in the truck. So technically there was no difference in outcome, just a difference in what I witnessed after the shot.

I still own both cartridges and would have no problem hunting with either one.

I'm sure your buck was a mess inside after 3 108 Bergers and didn't make it far.

 

[Elk Chaser]

Ha, that’s true. Hard to argue with this.

Peer pressure @Elk Chaser you better post that zombie CH3 up here tomorrow, couldn’t be more relevant. 20” 6PRC for reference.

I’m 9.7lb suppressed and would much prefer to be a tad lower, but it isn’t the end of the world.

Ask and you shall receive, unfortunately did not weigh just the stock before I put it back together but sitting at 9.25lb as pictured w/o bipod. Sure wouldn't mind it being under 9lbs but I'll survive and I'm sure it will shoot great...hope to find out this week sometime.

Also, Hornady 6mm 105gr HPBT will exit usually, and produces good wounds.

if one was looking for reliable exits and a blend of eldm type, early fragmentation internal damage with a good chance of an exit, would the HPBT be the logical starting point in the ~105gr load? I’ve had good success with the eldm from 22cm to 6.5prc but have had virtually no blood trails on heart/lung shots and my natural aiming point is not a CNS shot. (top of the heart/lung area)

just ordered a 21” 6prc barrel done up with a manson 6-6.5mm prc .100fb reamer so I believe the 100-105gr would be a logical starting point.
