Hi again guys,
Since I got a good load with the hornady ELD M 147 grains bullets, as you recommended me; I am ready to try new bullets and loads.
I've purchased the Sierra MK HPBT 142 grains. My powder is the RS60 (reload swiss), I can buy here the Vitahvuori brand, that as far as I know, some of you like it in the US but it is difficult to find in your country,
But, I prefer to continue with the RS60 because a friend of mine, has a gun shop and he provide me the powder with an affordable price. This swiss power is produced to use in the following calipers:
"
In addition, it can be used to load many short magnums. This propellant is perfect for high-performance applications and features excellent temperature behaviour.
Standard calibres
"
My rifle has 1:8 twist and Sierra recommend the MK HPBT 142 for this twist. I have not idea about the start load, because there is not data in google, but I found a chart to 140 grain bullets (hornady). In this case the sierra ones are tangent bullets so I might do saami reload to start.
Lets see, any advises are welcome! You know that, although I am European, I like to follow the American style and technique
