RS60 for 6.5 Creedmoor

[Disco_Richy]

RS60 will definitely chuck 143s from your CM. I had 3k fps from my 24" barrel (video'd the Labradar) with just very slight ejector swipes and no discernibly heavier than normal bolt lift, although the load I ended up with was a much more standard high 2800s. I actually favour 130s in 6.5CM now, save 140+ for my SAUM.

My CM throat appears to be holding up, my 6XC barrel also running RS60 and mostly 105 bergers or 100 pro hunters looked ****ed after 750 rounds however Still shoots tho, so

Thanks for your help guys. I finally settled on 42.5gr of RS60 for my 24", 1 in 8", Tikka T3X 6.5 Creedmoor with 143gr ELD-X. Grouping .25 moa and velocity at 2731 fps average with ES at 27 fps.

That’ll do!

It's a Tikka CTR, 600mm barrel and I think it is 1:8. I'll have a look in the loft tomorrow and find my targets from when I developed a load.

I do remember developing the load in the winter about 4⁰C and noticed a big jump in velocity when shooting in the summer around 30⁰C

Doesn’t the velocity change that your experience run havoc with your dope or aren’t you shooting beyond 300m?

A quick follow up - I`ve been getting some over-pressure signs on the odd cartridge so despite excellent performance and accuracy I am going to slightly reduce the powder load to address this. I`ll post my findings when proven.
