VERY suprising results today!!!
Seeing information as to what may be happening.
These shot here are all book loads. Comparison to a MP 402-200 best or top velocity was 1265 fps.
I shot these loads today to confirm chrono and 1250/1240 was shot.
I at first suspected blast over screens. But chrono was goodly distance away. Good 15-17'.
This is a slick sidded bullet. Seated as deep as needed to properly plunk. 1.205. Much shorter then the 1.260 max recommended. I wasnt happy with that but because I suspected NOT being able to reach my 1200 fps min requirement. Guess THATS a non issue!!
Curious on suspicions what actually happening. suspecting PC and slick sided bullet along with much greater bore contact.

So you did NOT use book loads. Anyway, there's your answer.

HA!
Well heck, I realise and understand short seating raises pressure. Same as LONG seating lowers.. I guess no one read the descriptions
The differences are the bullets slightly weight differences. All loads used Win cases MP bullet weighed 203 while Arsenals was 193. MP's had over 8g but the Arsenals was just over 7g.
Also Arsenal was a slick side and the MP a Std.
Chrono tested with known loads.
With lack of anything else I can think. OAL has to be a large part. Somehow I wanna thing the bullet design plays some role.
Anyone else find vel differences with a slick sided bullet.
