Load Data for 135g DRT in 6.5CM

[philcox]

Wondering if anyone has this and is willing to share?

PM sent.

@Formidilosus any chance you have a load willing to share?

Current components I have on hand:

• Brass: I have Lapua SRP and Peterson LRP
• Primers: CCI 400, CCI 200, Federal GM210M
• Powder: Varget, RL16, Ramshot Hunter

No experience, but from QL with a 134gr Hammer 22" barrel, case fill < 110%, pressure < 62,000psi:
RL16: 37.5-42 (42 = ~2871)
Hunter: 40-44 (44 = ~2841)
Varget: 34.5-38.5 (38.5 = ~2753)

Varget: 34.5-38.5 (38.5 = ~2753)

ps, the lower end of the range is just a 10% reduction from the QL calculation.

I would just start a groan or two under book max and work up checking for velocity/pressure.

Ok, ended up with the following for anyone else who is trudging down this path:

• 46.5g Ramshot Hunter (47 had slight ejectors, so out of the @Formidilosus book on Painless Load Development ... "dropped .5g and loaded up ...")
• CCI 200
• Peterson LRP
• Obviously 135g .264 DRT
• COAL 2.775 (per recommendation from DRT)

My 47g was 2896 (Garmin Chrono) out of a 21" (cut) Tikka factory barrel. I figure the 46.5 should be around 2840 ish.

I'll post my "group" results when I get to it over the next few days, and update velocity.

I never tried the Varget, and RL16 was slight ejector @ 45g and 2862fps

Trying to compile load data for all the DRT bullets there.
