Changing lots of hybrids

[BradY]

Ive had a batch of "fat" hybrids that have performed very well in my 6 dasher with 31.7gr H4895 and a 50 thou jump. Im now about to start a new batch of hybrids that measure much more like other 6mm bullets closer to 0.2430". I know I will have to re test them, just wondering if anyone has done it already and found they needed to up their powder charge at all.

Thanks

Just run a quick ladder at the longs from 31.5 to 32.2 and see what happens mate.

Found 0.3gr higher powder charge and same seating depth to shoot very well. This was a new lot of powder too so there could have been some variance there too. Happy days!
