Is the Norma brass not doing it for you? I got 200 pieces for christmas but still waiting on the barrel
I noticed a lot of you guys' loads are with standard LR primers. Any strategy with this or is it just what you have on hand?
7 saum is gaining a lot of popularity in F-class. Berger supports F-class a great deal. Lapua and Berger are now affiliated with one another so....
I have been shooting a 7mm saum for years. I currently have 7 barrels chambered and ready to go for my 2 full custom 7mm saums. I have also shot out several . I change my own barrels etc. I say this to prove how familiar I am with this cartridge . Speeds of 162 grain bullet at over 3300 is either from an extra long barrel 32-34 inches, a result of a faulty chrono or excessive pressure. I would hate to see people try to duplicate that speed as it would be down right dangerous. I am sure you will hear from others.
I’ve had friends with 162s going 3000fps from a 22” barrel pretty reliably.
At 30” barrel assuming 25fps per inch of barrel that would put you around 3200fps give or take depending on load and barrel variable.
I agree to get to 3300fps you’re looking at a probable chronograph error, really long barrel, a barrel that’s a freak of nature, or loads are really hot.
Not saying it’s impossible but something doesn’t add up at first glance.
Your 1.948 coal seems really short especially with 65.5grains of powder. I’m not even sure that’s possible.
Brass length alone for my saum cases measure 2.020” after turning and trimming.
What part of Texas? I’m in San Antonio area.great info guys et al. I am working on a new hunting load right now for the 175 ELD-X and or the 175 Elite Hunter. I picked up some RL26 to play with. its crazy hot here in TX so i am working on it slowely.
going to start 60.5 RL26 and go from there.
Looking to build a 7SAUM on a Nucleus SA, anybody have some wisdom on what reamer I want to shoot 180gr ELDMs?
Scott,I'm running an Defiance XM action can load to 3.25" Barrel length 26" SAAMI Reamer throated to .225 freebore
185 RDF COAL 3.10
60.5 RE 23
G7 BC .361
I’d uIDK never used RE22
I’d use starting loads for R25, R22 and R17 for the reloader powders you listed. The burn rates are a little different but not too much. You would be safe starting a grain higher than the starting loads in my opinion.I jumped into the 7SAUM world with a factory 700 SS. Put it in a Manners SL stock with M5 inlet so I can use Accurate Mag 300 WSM mags and load out to 2.95”. Mainly will use for hunting deer and elk.
Checked the distance to lands and I’m off the lands at 2.95 so all good there.
R-P 7SAUM brass, and use Tula LRM primers. I also have Fed 210GM and 215GM on hand.
I’d like to start with the 168 VLD. I have H-1000, RL26, RL23, RL16 on hand.
Could someone point me to some starting loads?
I've sent one from each of my 5 emails. The response I got last was that they have been getting lots of inquiries about the WSM & the SAUM, specifically the 7mm versions. So fingers crossed the 7SAUM will be one of the first when they do start manufacturing them.I would encourage all 7mm saum owners and potential owners to email Lapua asking them to make brass for it. If everyone keeps asking it may happen.
The new ADG brass is greatI've sent one from each of my 5 emails. The response I got last was that they have been getting lots of inquiries about the WSM & the SAUM, specifically the 7mm versions. So fingers crossed the 7SAUM will be one of the first when they do start manufacturing them.
