i would start at 58gr H1000 and go up on 147eldm. Depends on what freebore you have.

I’ll still be shooting a 6UM in ten years…. 6.5 SAUM is far from dead.

 

[Len901]

Thank you everybody can’t wait to shoot it I plan on keeping this gun suppressed

 

[Len901]

Today shoot the 156 with h 1000 first rounds down the barrel all around 2850 22 in barrel plan on trying the n 565 too

Looks like I need to try RL26 in my 6.5 SAUM Improved.

I’m currently getting 3050fps with 144 LRHT over H1000 with a 20” barrel.

I love my 6.5 saum, but if I were building a 6.5 wildcat today it'd be a 6.5-7 PRC like
Hornady should have done from the get go..

If there was ever head stamped brass for that wildcat i would be on board !!!!

Why do you need headstamped brass? Are you taking this rifle out of country to hunt? Pretty sure that's the only legality that involves "having" to match head stamp. I shoot lapua 6cm brass in my 22cm, 300sherman mag, necked to 7mm in my 7/300prc. Never been a issue for me. Perhaps it's just for your peace of mind? Or ocd? I can understand that.......

I fire formed brass for. 243AI for years. I wore out three barrels on that rig. That something I personally wouldnt wanna so any more. As well as necking down for a 6.5-06 rifle. I personally dont like brass intensive brass prep anymore. Which is a personal preference the older I get.

But on the positive side. I am following closely to see how Unknown Munitions build goes. They gonna do 7prc/6.5 with a improved 40degree shoulder and the +p throat.

R26 is pure magic in my SAUM. I bought a lot of it back before it became unobtanium, I'm good for 5 or 6 barrels worth of shooting.

Has RL 26 been pretty good with temps? Does it seem pretty temp stable? Do you shoot it in the summer and then fall?

 

[khuber84]

@Retterath rl26 is relatively temp stable till upper 80s for temps, then it's rumored it can spike in pressure. This is usually happening with guys running the edge of psi to begin with.

Ok. I appreciate the info

The 6.5 SAUM has a 30-degree shoulder angle. The Saum I improved gave me about 60 FPS. Not worth the effort, IMO. Now, what about a 6.5 SAUM IMP +P??

But really, everyone should be building a 6UM. LOL

Ryan,

I am looking at building a 6.5 saum so already headed down the "wildcat" route and was wondering if should just go deeper and make it a 6.5 saum improved. I understand how the change in the bullet for 280 to 280 AI made the cartridge better. As I understand it a 6.5 saum generally has a shoulder angle of 60 degrees, but if made it improved does that change it to 40 degrees? Also anyone know what the general velocity gain is from improving a cartridge? Like a % pump, since it will depend on the case capacity. With all that being said I am not the biggest gun guru so I might be out of my element on this topic, but looking to gain some insight. Thanks in advance.

I decided to go the improved and + P. Necessary? Probably not. But I want to do it so I am.

What is your barrel length and the performance out of it?

I just ordered it. I went 22 inch.

 

[goosedog]

Any feedback on the 6.5.saum imp +P is the juice qorth the squeeze? I will be getting a 22" barrel spun up and still havent decided if the imp is worth the fire forming brass or just go + P going to try n565 and h1000 with the 156s goal is to be in the 2950 to 3050 range without max pressure

Strictly for hunting purposes for me, so running it in an AI is a non issue. Ive even considered throwing the ole 270win in the mix here. But the differences in BC are more pronounced. But yet again, me, personally, could probably shoot a 270 just as good as a 6.5 SAUM or 7 WSM. I don't think I could capitalize on the better BC's to actually notice a difference in a hunting scenario
