16-18 inch shorty rifles

Completely your fault.

Try rl26 and 147’s
My 16 “ was almost 2700 while load developing , barrel should speed up after I get more rounds on it.

RL26 is definitely faster, but RL16 is also worth a try. I chrono'd these loads in my Sig Cross over two different trips.

147gr ELD, Starline, 210M, 18" barrel, 35 deg
RL16
41.5 - 2,545
42 - 2,646
42.5 - 2,668 fps

147gr ELD, Starline, 210M, 18" barrel, 55 deg
RL16
42 - 2,662
42.2 - 2,678
42.5 - 2,699 fps

I’m still doing load development, but getting around 2700 with 42.8gr of H4350. 2730 with 43.1gr of H4350. Likely going with 43.1gr as it was consistent single digit SD and obviously a little faster with only mild pressure signs. Now onto seating depth test.

Rifle is a tikka CTR with 18” carbon six sendero

To follow up on this, my velocity increased to about 2800 FPS with 42.5-43gr of H4350 in an 18” barrel after 100 rounds. I will be backing the load down to 41.5-42 to reduce pressure but impressed with the speed of the carbon six so far. Faster than the PVA it replaced

I actually have a 16.5” PVA barrel. What length was the PVA and speeds?
 
The PVA was 20”. I would get 2700-2730 with 41.5 gr
Not too bad. The MHSA spun up 24” bartlein was 2750-2770 with 41.5. I’d really like to be north of 2650 so I might have to venture up to 42.5-43. But I guess if I have too much pressure signs as long as I’m 2600 or higher I’m happy. I have 200 rounds already made up with 41.5 from the previous barrel so I’ll shoot those and go from there. Thanks for the info!

I should note that all my values are suppressed (omega 300). That likely adds some speed to my setup.

I get 2715 fps with Peterson srp brass, 41.4 gr Rl16, 143 ELDX, 18" Bartlein suppressed.

With the 130 Norma, 42.0 Rl16, Peterson brass, I get 2785 fps.

Remington 700 Classic in 7mm Mauser. The action is pillar bedded, and it uses the MagPul DBM bottom metal. (plastic, I know, but works perfect, and was way cheaper.) The free floated barrel is now 18" has a Surefire SOCOM three prong flash hider so it can fit a suppressor. (pending government permission of course)

Good caliber - nice setup. (y)
 
Has anyone done a short 16-18” 6.5x47? I’ve always been intrigued by the cartridge. Of course, I could just do another 6.5cm.
I have a 16" 6.5x47 built by Accurate Ordnance. It has a Bartlein #3 barrel topped off with a Thunderbeast 7" can, Manners EH2 stock. It's my whitetail rifle and has accounted for a bunch of deer with 123 Amax. Does well on steel out to 800yds. It's my favorite rifle by far.

18” 6.5CM is definitely where its at after playing with the 20” 308 barrel. I can’t wait to get handloads rolling to boost the speed up.
Do you know what that setup weighs?
I'm toying with the idea of ditching all my centrefires for an AT and just having a bunch of different barrels.

Just not sure I can get the weight managable enough for a hunting setup that will be carried a lot and shot very little.

Depends on what you consider manageable. I want to say it weighed in at 15.1 lbs. Even a 16" pencil barrel and lighter optic would still result in a rather heavy hunting rifle, but close to manageable enough.

Along those lines, I just bought a Kimber Montana for those times I really need a lightweight rifle. And then ditched my center fire rifles for a couple DT SRS where weight doesn’t matter. Still useable for hunting if I’m not walking a long ways.

I'm thinking if could get down to around 12lbs it'd be ok especially if it's short, I find short heavy rifles easier to carry than long unweildy ones.

I think 12lbs is unrealistic but dreams are free.

I know it’s not what you were asking about, but to give a reference my DT SRS A2 16” 308 is 11.2lbs as pictured. Maybe something to consider.
 
I really like that DT SRS rig.

For hunting, you even could get it under 11 lbs, if you used a hunting style scope (like a Vortex LHT) and light rings. As much as I love the ARC scope mount, they are pretty heavy. The mount alone likely adds at least 4 extra ounces compared to rings.

But I like it exactly as it is. Love the 3-18 Mk5.

Oh yeah. Could’ve saved 6oz going to the LHT and 4oz+ by switching to rings. Would’ve put me about 10.5lbs
