Re: .300 Win Mag, 180 grain bullet & Retumbo

I agree that RL-22 is probably perfection for the .300 Win.mag.I have worn out one barrel shooting it with fantastic results in both velocity and accuracy.
The problem I have is that it seems to be inconsistant in the different lots and seems to be intolerable to cold temps.I seem to lose 2 fps for each degree in temp. decline.
The ES and SD is all over the place.I have gone to H-1000 and have elimated these variables,although not as high in the velocity department.Accuracy is very good as well as very low ES and SD,many times single digits.
I have found, as you have that the E.S. spread with H-1000 is awsome,I am getting a 5 fpe E.S. in my 300 Win
Have you experienced the same with RL-22?Probably a good idea to buy RL-22 in kegs from the same lot and just adjust the load.

I have found, as have you that H-1000 is so consistent shot to shot. My E.S. is only 5 fps with H-1000 out of my 300 win
range it,check the wind, dial in correction, aim and only one shot
