If Retumbo is what you alredy have I would sure give it a go. I wouldn't start at 78 though, maybe 76 or no more than 77 grns as Hodgdon lists 78 gn as the Max amount. I would feel my way up from there checking for signs of pressure. Retumbo worked well in my rifle as to accuracy. I was just hoping to get a little more velocity with 8133 and it had the hope of not being temp sensitive and possibly help prevent copper fowling as it is one of the new Enduron powders. But the reality was that higher velocity meant higher pressure and I got the same pressure signs at the same velocity whether it be with Retumbo or 8133 I just had to burn a couple more grains of powder with the 8133.
Just a quick edit here as I just wanted to confirm that either 8133 or Retumbo gave me very good accuracy but then again I was using a bullet that is easy to load. Had to edit again. When I say 78 was a max load that applies to 175 gn bullets as that is what you said you planned to use.
Thank you much for your info! Yes 175 gn hope get out and do some testing this weekend. Thank you again.
