No, but close, the 540 has 1.75 % flame deterrent

They do have the same gravimetric density.

540 has a slightly faster burn rate.

How much MS do you have??

Thanks Mike. That was a good read linked there. My Goober search didn't find that one.

I don't have any 540MS but many pounds of unopened 540 which I (sadly) have inherited. What I also have is an old family recipe for a turkey-shoot load from the sixties using 540MS in low-base/high-brass W-W hulls. I have everything except the powder. Thinking to try the light charge with 540 and see how it patterns and the velocity.

Greatly appreciate the article.

Sorry for your loss Sad

I have loading data for 540 if you need it

Also Win 540 is the SAME powder as Hodgdon HS-6

I have load manuals with the newer 540, but thanks for offering. Just trying to recreate the old turkey load for nostalgia sake. Smile
