That's really quick considering the charge weight.Same charge as 162s going 2824. Sticky bolt sometimes at 42.6 with the 180s so its close
Howd 45.3 shoot? Being dead of summer and just under pressure with 2000MR which isnt exactly temp sensitive that might be a decent nodeIf anyone's interested, I tested the 2000MR this morning.
Ran a ladder and had these results:
Projectile: Berger 175gr Elite Hunter
Primer: CCI 450
Barrel Length: 26"
Charge Weight (grains)/ Velocity (fps):
42.0 - 2622
42.4 - 2619
42.7 - 2664
43.0 - 2665
43.4 - 2682
43.7 - 2697
44.0 - 2723
44.2 - 2759
44.7 - 2773
45.0 - 2796
45.3 - 2807
45.7 - 2816 - Slightly flattened primer
46.0 - 2827 - Flattened primer, slight flow
46.2 - 2852 - Flattened primer with flow
46.4 - 2872 - Flattened primer with flow. Slight heavy bolt lift
I only shot single rounds to look for rough node locations and find the upper limit. I'm thinking of running the next ladder between 45.0 - 45.5 gr now but am definitely leaning toward 45.3gr.Howd 45.3 shoot?

180 ELDMs in a .150fb I'm hitting pressure at 2760. 27" tube. That's with varget though. I think RL26 will get me there or higher without issueFor you fellas with the SAW Type II chamber, you'll get higher speeds than this I'd suspect. Mine is Type I with a freebore extension (0.100" freebore)
I had compression with the 175s and RL16 from 45.0 grains so I didn't fire those today. No need to now. RL16 was awesome for the 160gr class projectiles though. I'm keen to hear how you go with the RL26. I'm going to start hording RL26 I think as I want to buy a 7SS reamer and a tempest magnum bolt to run in one of these rigs. RL26 is rocking horse shit in Aus180 ELDMs in a .150fb I'm hitting pressure at 2760. 27" tube. That's with varget though. I think RL26 will get me there or higher without issue
RL16 didnt work. Crunch crunch.Ever try 4451 or R16 in 7SAW.
I was really interested in the cartridge but decided I wanted more cowbell
What is min barrel length for complete powder burn?
Could be great application using in a hunting rifle. Thinking a Barrett Fieldcraft has a 3.00” internal mag box, could rebarrel and have a light handy hunting rifle, go as short as 18” suppressed. Or try the same with a Tikka (change out bolt stop to their intermediate 6.5x55 length) or even the 700 SA I have laying around.
Would extend range over the standard 7mm08.
From what I understand from talking to Clayton at WTO with the heavies RL16 is the way to go.I'm planning to shoot the 180hybrids well over 2800fps in the short chamber with alpha brass and 28" barrel.
I have varget and h4350.
Should I just order some reloader 16 or try what I have?
That’s no worries mate, that looks a shitload better than the configuration I had it in.Hey guys.
Only just started playing with my SAW. It has the short throat chamber so I decided to try some Berger VLD 168gn Hunters as they have a short Base to Ogive.
Rifle is a Tikka T3 running a 26" Proof barrel, 8 twist. Manners carbon prs stock with mini chassis.
These results are with only around 50 rounds down the tube and during fire forming Lapua brass. Should hopefully see a jump in velocity once i shoot it more and use the formed cases. Accuracy has already been fantastic.
Powder - Varget/AR2208
Cases - Lapua Palma
Primers - CCI 450
Projectiles - Berger VLD Hunters 168gn
Ladder Test 1 - 0.01" off lands (2.1095" CBTO)
Ladder Mini Test - 0.005" off lands (2.1145" CBTO)
Thanks to Simia Del for your help (plus the barreled action )

That’s easily achievable. I had safe loads with 2000MR at that pace to about 2750fps. Results were not reliable though.Oooops.
2700. Fixed it
