I'm working on a load ladder in my 20" Monster barrel, AR style of course, for some 90 grain bullets, 90 gr Tgk, 90 gr Eldx, and 88 gr Berger FB.
Using RE15... still looking at my data (the Hdy 87 for reference) but one thing strikes me:
Is it just me or does RE15 make for some hot brass, hotter than the brass when I've been using Lever? or varget (did some of that, but mostly Lever)?
I fire my ladders one at a time from single-loaded mag. All of it seemed noticeably hotter in temp at ejection...

I found the Hornady 87 gr data to be too hot for the 90 gr Berger BT Targets and 90 gr Lapua Scenar L's. Hot loads = Hot Brass. I sheered my Toolcraft bolt below 87 gr Varget max with the Scenars. H4895 was also too hot and was reminiscent of a peaky 6.5G XBR load. And these were in a voluminous 243 LBC case.

I am still waiting for my 6ARC upper to come in but I was planning on trying Reloader 15 with 95gr TMK's. It's turned into a "use what you got" world. How is it working for you and where are you starting your ladders at?

Those 3 ladders were kind of an experiment on my part. I put the RE15 back on the shelf, and pretty much now am using just Lever for most of my 6Arc loads. I also have some CFE and 2520, and PPV, so for now don't plan on using any more RE15. The hornady data however, has RE15 data for its 95 gr SST. Work up carefully, and it should be an ok guide for the TMKs. I used the 87 gr data for my 88/90's ok.
Check your seating Coal lengths before you start. SST's need to be kinda short, the TMK might seat ok farther out.
Hornady also lists Varget for that weight by the way.
The Hornady data is for an 18" barrel fyi.
