20 practical load data

[jagter8]

I'm currently putting together a 20 practical! Working with an 18 inch barrel. Wanting to run 40 gr vmax. Anyone have a good starting out on load data?

On my second 20 Practical in a bolt gun.
H322/H4198/H355/N135/N133/LT32 have all done well for me with 39SBK / 40VMax.
Favorite load is [email protected]. Powder availability and temp stability is why I like this powder
Not necessarily bug holes, but it shoots both bullets the same way and if I was to go down in charge or up in charge, it's still shoots really well.
