@puku, hey thanks, but I am going to try BM2 first though as it isnt compressed at all. I just need to find someone selling 500g, so far its all 1kg. From my initial loads I think the accuracy node is right up at the load limit (as I increased the charge the SD and accuracy improved) for both 69gr and 77gr so not compressing seems the safest way to experiment near the limit Once I can see which is the most accurate I might try 75s unless 77s do better and then maybe 80s, but I'd be surprised in a 1 in 9 twist if 80s fly.
How do you find getting 75s? they dont seem to be as commonly available?
