Short barrels

[cbynum80]

has anyone played around with a 6.5 prc or 6.5 rpm with 18” barrel or something similar?

Wouldn’t that make it a creedmor?

 

[cbynum80]

I would think a little faster than a cm but shorter and a suppressor

Thread '6.5 PRC/SAUM shortest barrel length'

Dec 24, 2024

Current build is a 6.5PRC or SAUM built with the following:

ARC CDG short action
TT primary
MDT HNT26 folder
Atlas Bipod
ATACR 7-35 (MOA for all you haters)
TBAC Ultra 9 (compensating for something)
H1000
Hornady 143gr ELD-X
Hornady once fired brass (will probably buy Lapua)

I’m not settled on barrel length yet. I’ve seen some run down to 18” with good performance. Looking for some of you guys with experience in your builds. I’d like to shoot out to a mile. Shoot coyotes out to 1000. Shoot deer and elk out to 800.

Thread '18" 6.5 PRC Real world data and velocity.'

Feb 2, 2025

I am currently working on load dev for a Tikka Veil wideland (cut to 18" and threaded by class 3 machine before he passed). I initially began load work with the 135 A tip as I had a few hundred and H4831SC and that seemed to be the recommended powder for short PRCs. Results have been relatively disappointing so far compared to what I have read.

This rifle has roughly 90 rounds on it, so the barrel may speed up still, I just have not personally seen Tikka barrels speed up much in the past.

All load dev currently has been done with new peterson brass, and federal LRP (non magnum).

Thread '6.5 PRC velocity and barrel length?'

Dec 8, 2019

Just curious what people are seeing for real world speeds.

What brand gun or barrel?
What bullet and powder or factory load?
Barrel length?

Thanks. I'm interested in getting one but want to see how much real world speed I gain over the 6.5 Creedmoor.

Just finished a Kimber Montana with an 18” Mullerworks chambered in 6.5 SAUM. I’ve only tried Magpro because I’ve had great results with it. I’m running 135 Bergers at 3000fps without much effort. I also got 156s to 2800fps with pushing too hard.
If a 6.5 Creed can make the same velocities the pressures would have to be way beyond safe.

Wouldn’t that make it a creedmor?

Creedmoor speeds with extra recoil essentially… I guess you might be getting a touch more velocity.. but not sure if it’s justified, which is why I sold my prc.

Definitely not achievable with an 18” 6.5cm… not hard to do while hand loading for an 18” 6cm I imagine though. But barrel life is going to be short with speeds like that if it matters to you.

Just getting an 18" barrel in 6.5 PRC broken in on a CA MPR. Average of 2730 to 2780 depending on which factory load. Only about 50 rounds into it so it might speed up a bit yet as it breaks in.

 

[Pilsner]

Rounds 50 thru 100. Noticeable jump in velocity - leveled out at 2850-ish today after another 50 rounds. As velocity went up groups shrank. Last 7 shots went into 1/2" at 100y before we lost daylight.

Edit after checking range session on the Garmin:
ES and SD went from 90/35+ down to 33/22. Wasn't expecting that but I am not going to complain about it either.
