22-250 loads with RS60

[Thoburns]

Have a custom from dolphin throated for 77G TMK and it one holes with RS60. Tried a 65g sierra with varget and it's very good but could be better.
Anyone got start & max load data for RS60 and the 65g bullet?

Excellent velocity and accuracy with 55gr Sako gamekings and RS60

For 69gn bullets I use 38gn RS60

Any idea what the start load is on the 69s ? I could do the calcs from there if you have it

There was no load data available (probably still isn't) from memory I started at 36gn and worked up, I don't have a windows laptop anymore so can't run it through GRT. 38gn gives no pressure signs but I have a slower twist than you
