I like Blue Bot and I have used it for many years.
I was looking thru Quick Load and discovered BD might make a good 350Legend powder.
28g + was a top pressure loading netting 55K with my chosen 200g bullet. I started at 25.5g FIRST shot was so hot the case was swaged into the bolt head and took some doing to remove it. Primer fell Out and case had a noticeable ring where the case was above the bolt recession. Bolt lift was resistant but opened. Rifle is fine.
Once home I pulled every load and checked everything. All where loaded as they should and spot on for powder charges. Mow the one fired coulda been different but the charge was 70 ish precent fill, IIRC. So no bdl chg BUT SOMETHING HAPPENED!!!
I read that BD isnt advisable to load in 41 mag or Light 357 mag???? Maybe what ever causes that recommendation also applies to 350 Legend. Cast & powder coated lead bullet
Juat wanted to mention maybe someone has a answer.
You started WAY TOO HOT. You can back Blue Dot off a long ways, all the way down to subsonic speeds. I suggest you start there. I'd have started at somewhere around 15 grains. You can always add more, but you can't add less after the rifle lets go. I'm not sure where the 28 grains comes from, but that seems like a case full under a 200gr bullet. I guess working up pistol powder loads for rifle cases really isn't for everyone.
