Thread: 6.5prc

I thinking to joint the prc club but not 100% on it yet. The current favourite shooter is a 22" 6.5 creedmoor which has done everything Ive asked for with 143's @ 2700fps. My ideal outcome will be to have a 20" or 22" that can do 153gr or 156gr @ 2950fps + without to much fuss. Is it realistic or just a dream?

Alright, I've joined the club. Looking forward to playing with a new caliber. Factory ammo to start so I can get used to it and build up some brass, reloading later.

Well done, how much factory are you going to send through it to build up brass or run it in? What powder and projectiles are you going to use? Exciting times

Exciting is an understatement

So I've got 40 rounds already, Norma bondstrike ammo.

Powder I'll use 2217 or Superformance.

Projectiles I'm not 100 percent on yet, I've got @a box if 147 grain ELD-M and 50 140 grain Nosler BTs. No dies yet so I think I'll get another box of bondstrike next and then find some dies, so I'll have 60 ish pieces of fancey Norma brass from the get go. I'll get it threaded for a can at some point too.

My 6.5-284 (as close a cousin as you'll ballistically ) get to 6.5 PRC) build is coming together too, action arrives tomorrow, stock and barrel are in hand. I've also got cases and Superperformance ready to go. I've got a spare tub of SP if anybody needs some.

More details mate? Sounds good a work mate of mine shoots 6.5-284 loves it

I started another load for my 18" 6.5PRC. 147gr eld-M. The 143 eld-X are too hard to get now.

I tried two powders to start ( 2225 and RL26) and two primers with the 2225.
Looks like it'll shoot this bullet in good 100m groups with even a large powder variation.





I made a mistake trying something new. I used the 6.5 mandrel for the neck turner to size/true the new lapua case necks. This wasn't enough neck tension or consistent after chamfering and deburring (which i had some issues with and would have varied tension) the case mouth. I could feel a large difference when seating the bullets. This caused the poor velocity numbers. I was really only looking to find max charge/pressure not a velocity trend so it didn't matter really
I used the F/L sizer only on the 1x fired cases after this and the expander button as a mandrel on the rest of the new brass. There was more consistent bullet seating and higher velocity also.

Some follow up loads with 1x fired and some new brass.




I had issues this day getting the Magneto speed bayonet fitted tight/properly which cost me a few readings and a poor group for the 2225 57.5gr load.
The 57gr RL26 load was too much pressure for my liking even though it grouped well.

What max vol are you hoping to get with your top load of RL26.
I just ran a ladder test for pressure through my Creedmoor with the 140 targex and Hodgdon superprofrmance i got 2818fps at top top charge with no pressure although i wouldn't want to go any higher

i was hoping for 2800-2850fps. i did get to 2800 with 56gr rl26. I'll check out 56.5gr when I get some more 1x fired brass to finalise the load to get to 2850fps.

@Roarless20, that's interesting. I'm using ADG brass with 147gr ELD-M's and Federal 210's. You've seen an onset of pressure signs with the same two powders I've used, at charges that were absolutely fine in mine (I even shot a competition with 57.5gr of Re26).

I'm picking the Lapua brass maybe has a fair bit less capacity? Have you measured case capacity by chance?

Good example of why to not get your load data from forums or skip doing the workup.

I haven't measured the case capacity but I might when I get the time. I have a couple 2x fired lapua and 7x fired hornady to compare.

I'm running a suppressor which could be causing the earlier pressure? or I have a tighter chamber/barrel? I could shoot 57gr but don't want to trash the brass early as it is bloody expensive and hard to get.
Its a lightweight 18" barreled hunting rifle so don't really need the fraction more velocity of the hotter load. Even 2800 fps is more than i really need.

I would be disappointed with 2800 from 147-143 as i get 2811fps from a 18" .260.
See people's results is the main reason i haven't made the move and i use 10 grns less powder.

How many reloads you getting out of that brass? What bullet weight in the .260? Caus that is fast as for 18" .260

Some brass is probably up to 4-5 times in one .260 and would probably expect 6-8 times but will probably loose most before then.
The .260 and Creedmoor is a very efficient case.

I took my brother-in-law from Aus out with me to shoot my follow up load tests a couple of days ago. We shot some test loads on paper with the 6.5prc and the .223 then out to 470m with the .223 before shooting 700m with the 6.5. A couple of young cats were shot right close to us while we were shooting the paper which was a bonus

i loaded up some of the 56gr RL26 fed210 147 eld-m load which i'll use to fire form the new brass. Also finished shooting a 2225 57.5gr load i didn't get time to shoot previously.





Much better velocity consistency and accuracy after correctly sizing the new brass necks this time. I'm happy with the RL26 56gr load accuracy with the magneto speed not attached. I wont bother doing a seating depth test with this load.

My Bro-i-law (a non-shooter but a natural) shot three of the 147gr rl26 56gr load at the gong at 702m after i had it on target (tricky tail wind over hill country) with the last of my old 143gr eldx loads.



The actual group size would measure less if you allow for the 0.1mil up click i dialed after his first two low hits (approx 0.3moa). I had my camera on the target so know exactly which hits on the gong are which.
