Thread: 243 load advice 1:10 twist winchester mod 70

Right so finally got to spend some range time.
Running Sierra prohunter 100g over 2209 ADI powder.
Unfortunately I didn't have access to a COAL gauge so I worked out COAL by feel.
As luck would have it I was close but had seated them to be just touching the lands according to my mate who measured after I had already loaded the ladder.
Results were as expected and I will now do another ladder at 40.1, 40.2 and 40.3 grains and seat them 20 thou off the lands now that I know.
On a side note I need to buy a set of comparetors too.
Also in my haste I forgot the bloody chrono so I'll need that next ladder.
No pressure signs at all.
