got round to loading some up today
used starline brass
cci 400 primers
and lever revolution
loaded 5 rounds each of 27.0,27.5,28.0.
according to GRT 27.0 will produce 38283psi and around 2134fps from the 20" barrel.
28.0 will produce 43302psi and around 2221fps.
considering 6.5g has a max psi of 58000 psi this should be a good safe place to start.
KS:
Really long OAL. Are those bullets 'bore riders'?
LR-55
