Hi, folks.
I'm reloading my .375 H&H with Peregrine VLR4 230gr bullets, using Lovex S062 powder.
However, I'm battling to find a stable velocity which also GROUPS well on the target. I'm seeing a BIG discrepancy, though, between what the target velocities are on this XXL site, versus that on Peregrine's website. XXL has the target velocity at 2710 fps, where Peregrine has the velocity at 2920 fps.
Personally, I think 2920 fps for a 230gr out of a .375 is rather fast, but that comes from the manufacturer.
Question is - what should my goal be? Do I aim for what the manufacturer says, or go by the XXL load data?
Any advice?
I agree with spricht Deutsh, but add that in most cases the trim to length is usually 0.010 shorter than the max. length. It is most important to maintain a uniform length for all your cases if you are crimping the bullet, especially if the bullet has a crimp groove. You do not need to worry as much if using a Lee Factory Crimp (LFC) die, because this crimps the bullet with horizontal pressure, and not at the end of the case. Not sure if the die is available in your round, but worth looking for. Enjoy days at the range.
