Sorry didn’t get an email showing a new post.Where is this forum?
Im looking at putting together a fairly light weight hunting rifle in 6.5 PRC with 24" barrel primarily for the 143 gr ELD-X. As far as twist rate goes, 1:7 or 1:8?
Conan
Why 1-7? I was pricing around some builds and was pricing 1-8......maybe a 1-7.5 will be a good happy medium?Short Action Customs recommended 1:7 on my 6.5 PRC.
Wander if lighter bullets will stabilize/over stabilize with the 1-7?
How low could a person go with the 1-7?
Thanks. I know I wasn’t specific in grain but I was more or less wandering about lighter bullets than that.Im going to run 143s, i guess ill let you know when i get it.
You don't need a 1:7 for 147's. 1:7.5 is as fast as I'd ever go, especially with a PRC. Factory 147gr creedmoor ammo is running in the mid/upper 2600's and is fine in all those 1:8 twist guns. At 2900+ you'll have no problem with a 1:8. Even the new 135's and 153's were meant to work in an 8 twist.
How lighter bullets will work in a 7 twist is they'll blow up. I've run 95gr Vmaxs to 3900fps in my 6.5 SAUM 8 twist (HOT load), and they were on the edge of letting go (over 350k rpm). 123's or heavier will probably be fine in 1:7 or 1:8.
I ended up getting a barreled action ordered and ended up getting a 1-7 twist 4 groove Krieger......what is the lowest grain bullet you have tried with a 1-7?I'm having good luck w 5R 1-7 w 147 ELD. If anyone wants to try Sierra 150 i have 49 for sale in the reloading section!!!
Ok.....Thanks, let me know how things go.Im working w Warner Flatline 123 but solids don't count.

Any results? I’ve got a pack sitting on my desk and would be interested in any data you could share.
I just found some at sportsman’s warehouse online. I had it shipped to my local store in Reno from Carolina. The website still showed some in Indiana I believe.Anyone have brass in stock?
Email Dan ,
he will send you load data.
RL-26 is what i used. Always works up your loads. There has been 3 different 6.5 PRC reamers that i know of. Mine was .188 FB
140 hybrids @ 2.950 and they were jumping .085 with my .188 FBThat's actually great news. With Accurate AICS WSM magazines, I can go with 2.950 COAL. Sounds like that's nearly what you're running with SAAMI chamber spec. Did you happen to load any at that COAL, and did they shoot well? I'd love to stay magazine fed if possible in my SA.
Measure your accurate mag. I mag fed them at 2.955 no problem. I also have a Alpha 300 Wsm type 4 which has almost 2.980That's actually great news.

Barrel length 24” or 26” non suppressed??? Looking at a proof carbon in one of those lengths. Wondering what the data is on 143 ELD-x, 147 ELD-m and possibly 156 Berger EOL elite hunter.
If you are willing to put up with the length and mass of a can, why not just get a longer barrel?
From the hours of research I’ve done, I’d go with the 308. In fact, IMO, that is exactly where the Chris Arms MPA accels. I’ve fondled that 308 at a local dealer. And the guy behind the counter owns an MPR in 308, for feel/elk hunting as well. Tons of ammonium options, more than the 6.5CM, and much much more than the 6.5 PRC.I'm doing my research on the 6.5PRC...seem like you don't want to drop the barrel length below 22" to really get the benefit of the cartridge over the creedmoor. So if Im wanting to build a hunting rifle..western big game....barrel length 16-20" should I just go ahead and build a 308 or 6.5 creed? I was thinking of running a 20"PRC but if it's all going to be wasted performance then maybe the 308 or Creed is the better bet. I want a short, handy, accurate, 500yd Elk Slayer. I wouldn't mind running it suppressed since I already have a Titanium Can....
What do you guys think?
Thanks for the reply...Thats what I was kinda thinking...build a really short handy 308...collapsable stock and all that. That will be a great rifle for everything but shooting across Canyons. For the long stuff a lot can be said for calibers like my 300WM. I currently have a SAC 260 with a 22" tube. The rifle shoots phenomenally well but as it sits, it's just to heavy for me to lug around these mountains. There's a big difference in hunting off an ATV and backpacking for a 4-5 day hunt. It all adds up. I'll keep you guys posted on what I order.From the hours of research I’ve done, I’d go with the 308. In fact, IMO, that is exactly where the Chris Arms MPA accels.

And for context, I have a 6.5CM in RPR, and have a 6.5 PRC on the way.
Ya I was wanting to have some load development on this thing by now but it was a little late to get to me, oh well. It came in just in time for deer season and the way it looks is good to at least that range. Anyway, was hoping to shoot a mile with it soon but now finding forester dies in this caliber is all on back order. Hope you can get yours soon to play with.Cool, IHFarmer07. Still waiting on my barrel... I'm eager to see how far this caliber will reach.
