Hello folks! Here I have a brand new RPR in .338 Lapua and I'm loading for this rifle and caliber for the first time, trying to do my best for long range accuracy.
To maximize the accuracy, I assumed I was supposed to sit the bullet as shallow as the bolt can close, at this moment the whole cartridge length is somewhere 3.9"+ I don't remember exactly. But at this length the whole cartridge can't come out through the ejection port, unless I pull out the bolt, and the cartridge is too long to fit inside a magazine.
To let the cartridge fit inside the magazine and able to be ejected out as a whole cartridge, I need to sit the bullet further down, resulting the whole length to be 3.7625".
I got my reloading recipe from a person who has the same rifle and I'm certain he did put tons of work into developing the load. So with the same bullet, brass, powder and primer, his cartridge overall length was set at 3.7250". Unfortunately there's no way for me to contact this person any more.
So assume the recipe I'm using is the best for this gun(I will develop more loads to compare in future but let's set it aside for now), should I sit the bullet to 3.7625" or 3.7250"? Or toss the magazine and sit for the maximum length 3.9+"?
