120 class powders

[myrifle]

I did see some big jumps, and is that ladder bad ? ? ? I didn’t shoot them for groups yet. The magnetospeed kills my groups. I do wish just once I could get a load with low sd and it group good at least 3/4 moa and be consistent. I believe his method will work fine getting low sd consistently but I have yet to get small groups using it. Most of the time my low sd groups ain’t pretty lol. Well it’s not really funny.

Powder charge first for tiggt/low sd/es.

Then seating depth too close up the groups.

Personally I find the scatterlee method too be worthless.

If it was me I would rerun that ladder but do 3 to 5 shoots per charge, letting the barrel/chamber cool between charges.

Then find a node in that ladder too test seating depths around.
