Crimp question

So at the last BE practice I tried my new mounted dot On my stock RO  4.0 gr BE 190 gr swc lead .463 crimp on a friends recomendation. That load destroyed the bull at 50ft. A salty dog gave me some of his wst loads on 200 gr lswc and also destroyed the bull. I liked the feel of the wst and it was for sure cleaner.  I’d like to load up some of the 190,s I have with the wst but was curious if I should try the same .463 crimp with the wst.  I like the BE load but a cleaner powder would be nice. 

Btw the 11 pound recoil spring seemed t work fine. Was wondering if I went to 12 if it changes the feel of recoil or change function much.  With the 11 I had a few stove pipes but after some more lube no more issues

And lastly. Have I mentined how mu I’m hooked on BE shooting now. Good lord it’s fun

I still load old school. .463 works for me on my lead loads. Don't even try to spit the hook. Sounds like it is set pretty good.

.463 to .465 on lead.  .468 to .469 on jacketed.  50 yard tested.

I'm also on board with .463ish and WST.

Outstanding. Thank you gents

Any thought on the spring?

And no way I’m spitting out th hook.
