Has anyone tried Ramshot LRT in their 6.5 SS? I really like the low pressure node I run in my 6.5 with RL33 & 160 Matrix. I also noticed that there was some data for LRT in the 6.5 PRC. Got me think it may be worth trying out as RL33 is nowhere to be found.

HEXBN 160 Matrix, WLR, 64grs RL33 @ 3140. I'm running a 30" Bartlein tho. I've run upto 67 grains almost cracked 3200'.
Wondering if any 6.5 SS shooters have tried the Badlands Precision 125 grain bulldozer 2, and if so what you found for accuracy, load data, etc?

Looking to build a 6.5 SS on a Kelbly Nanook short action (.532) 20" barltein 5r 1-7.5 twist. Wyatt's MBE-4 box. Is there anything that I need to know that I could be missing OR recommendations? I'm hoping Rich has the rental Reamer, brass and dies in stock? I'm curious too, will I need to neck down the 6.5 brass?

Sorry all, I accidentally cut the top paragraph of my post above…
Thank you guys for all the input and good reading regarding the 6.5 SS. It sure sounds like a winner to me. I've got a 18" 7SAUM that is a joy to pack, but I'm wanting something else. I had a 6 Creed built for my kids and thing is a hammer. I've been wanting to do something on a custom short action so between the 300 SS and the 6.5 SS, I think the 6.5 is a clear go to for staying with a short action. Thoughts and suggestions are appreciated! Please see the second half of my post above.

You will neck down .284 brass. Hope this helps.

Finally got the right scope rings in! Now on to some break in and load development. I'm going to start with Berger 140 Elite Hunters and go from there. The 156 EOL bullets are what I plan on shooting…once they become available again.

Hey all,
Going to resurrect this thread. I'm new to this group and am really interested in the 6.5SS. I was wondering what everyone is doing for brass prep on the 6.5. Any neck turning? Trim length after firing if needed? What bushing size people are using for proper neck tension?
Thanks

the only brass prep is necking down from 7mm but no turning and fully formed. You'll probably want a .291" bushing.
Trim length is 1.950"

What is your load for the 129 AH? I should be receiving mine today in the mail!

Thread back up just to share some load data for reference. Before and after 4" barrel chop. This is for reference only--your barrel is different--start your ladders wisely.
All loads listed are my 6.5SS with CCI 250 primers, the same 50 pieces of ADG brass purchased in 2021, & same 8 twist barrel -- first at 24" length then at 20" length. All shot with 7" suppressor
24" LONG BARREL:
20" LONG BARREL (same barrel, chopped and rethreaded):
