6.5 saum

[jwing]

Was looking for load date. 130 to 142 bullets

Will you please share some load you guy have tried!

Where did you get your dies?

I havn't used the 6.5saum but have built a couple of 6.5WSMs for people. I would give R25 a try it has worked great for me.

Try Retumbo for your 140's. RL 25 is good also but Retumbo is much less temp sensitive....Rich

The two powders I've used are 4831sc and RL19 with the 130 AB and 142SMK. Overall the loads that I list below are each fairly accurate with no pressure problems. The RL19 loads were a little more repeatable velocity wise so I've continued working with them and some 140 VLD's. I've been busy of late and haven't shot the VLD load yet but hope to soon. Hoping to end up around the 3100 mark with the 140's and RL-19. RL powders are more temp sensative but my Shooter app on the android can account for that so its not as big a deal for me. If its important for you than you may want to move forward with the 4831sc.

Best of luck.

52.5 gr RL19 - 130 AB - Fed 210 - MV Avg 2913 - ES 66 - SD 18.26
54.5 gr 4831sc - 130 AB - Fed 210 - MV Avg 2985 - ES 30 - SD 11.65
54.0 gr 4831sc - 130 AB - Fed 210 - MV Avg 2967 - ES 35 - SD 19.92

52.5 gr 4831sc - 142 SMK - Fed 210 - MV Avg 2841 - ES 54 - SD 21.08
53.5 gr RL19 - 142 SMK - Fed 210 - MV Avg 2906 - ES 22 - SD 10.05
55.0 gr RL19 - 142 SMK - Fed 210 - MV Avg 2975 - ES 18 - SD 6.62

thanks

that will give me some starting points.

why is the 6.5 saum not very popular?

Good question; I've seen it shoot some great scores in 1k matches... I even thought about turning my 1k .300 rsaum into a 6.5 a few times.
You might look at loads for the 6.5 Remington Magnum for some more load ideas. See what works best in it. I believe the 6.5 Rem Mag case volume is about 69grs H2O... the .300 rsaum 72grs H2O your 6.5 rsaum is got to be close, base on either the 7mm or .300 rsaum

I will check out all the 6.5 mag load data. thanks for your help.

Let you know in a few week what I find out.

My guess is that there are just so many other 6.5 variants out there that are more popular or have been popular longer. The SAUM is fairly new in the standard cartridges of 7 and 300 so the wildcats based off of it are slow to come with all the other glut of 6.5 calibers available. Plus there are no "mass produced" dies or factory ammo like the .264 or 6.5-284.

In addition, the 6.5 Rem Mag was made about 50 years ago and is basically the same thing. It's a good caliber in my opinion. Good velocity, short action platforms, and 6.5 ballistic coefficients are a good combo.

Quite a few guys have necked down the WSM because it has slightly more case capacity but the SAUM has a better neck and you will lose very little velocity....Rich
WSM around 78 grains. Saum around 74.

reading is making dies 6.5 x 300 saum hope to have it going in next month, got to get the beding done and stock sent off for painting. then i will get it rolling and see what I can get out of it!

I think you will like it. My 6.5 is a screamer and very accurate.....Rich
