Thread: what weights?

Id go up in half grain steps, load 1 of each from starting to maybe a full grain over max.
Shoot all bullets in order at the same target marking each shot and examining each case for signs of excessive pressure,STOP firing if any show signs of excessive pressure.
With any luck your target will show a cluster of charges that shot close together, say 43 43.5 and 44 for example.
Now load up a few of each and shoot for groups.
Hopefully you are now happy but if not try .2 either side of the best.

Dont get stuck on the factory overall length, most bolt actions magazines will handle ammo loaded out to 74-76mm and function fine thereby increasing powder room, you do need to know how to find your just touch length tho.

I think you will struggle to replicate the superformance load especially with 2206h for velocity but you should find another velocity that shoots well.

2208 and 748 are great powders for 150gr projectiles also.
