Well that was unexpected

Post by dashooter »

Loaded up some 129 gn SST's in the 6.5 last night. Tested them out this evening.
Quickload showed 3000psi under max and a estimated speed of 3327 fps.
Group could have been better (first shot killed it).
Might back off a grain in powder and test again. Cases have ejector mark on the base.

Group photo should be rotated left 45 degrees. The outlier was low and slightly right.

Be interesting to see what happens when you drop the load of.

The powder you loaded might have loaded a slightly faster burn rate than Quickload

Yeah, keen to see the difference too. Its either a faster batch or maybe chamber is a bit tighter.
Time will tell i guess.
