So if we load a 300 Win to perform like a 308 in order to achieve accuracy, whats the point to the 300 Win?
I think most of us have been led to believe that we obtain best accuracy by playing with charge weights of different powders, and also trying different brand bullets.
But what about optimum performance?
We dont get the BC results without having velocity.
There are actually few powders that will give that in the larger capacity cases.
And the larger the capacity, the fewer there are.
So if we want to use the highst BC bullet, which is always the longer heavy ones, along with the highest velocity, how many choices are there as for accuracy testing?
The first thing to look for is (Max) velocity, and we do that first by loading one round at the lower end of the max charge range, and one more round one grain heavier, and another one grain heavier than the last and so on.
We then shoot those into something safe like a dirt pile at any distance with no target.
When we reach the point we notice even a slight amount of bolt sticky STOP,
We now know the max load in that gun with that powder/ bullet combination.
All this needs to be done over a chronagraph in order to record the velocity.
We might have used five rounds to find the max load in total for that powder.
We now load three rounds with the max load and fire them for group at 400 yds preferably or as far as we can.
Then use different seating depths in order to fine tune for accuracy, BEFORE reducing the powder charge.
And that my friends is the best way to get MAX performance from wildcat and magnum cartridges without spending days and countless rounds looking for it.
First find MAX velocity, then attempt to make it work by changing seating depth before moving on by lowering the charge of powder.
