150 grain Hornady Interlock factory load

[Slick Pilot]

Does anyone have load data that will match the factory load in 308 Winchester for the Hornady Interlock 150 grain bullet?

Thanks!

Best thing to do is chronograph a factory round, then look for powders that will give you the same results

May I borrow your chronograph?

Very hard to duplicate factory loads. Start with the bullet you want to shoot and work up a load that you are satisfied with. You will waste a lot of time trying to make it work exactly the same. The same velocity won't get it either, but it may be close. You will still have to do a load work up.

Realistically, factory ammo often won't match advertised velocity. Not because it can't, but because most hunting rifles are shorter than the test barrels that the data was derived from. And, there is a proprietary power the manufacturer uses (that's responsible for the high velocity) that's unavailable to reloaders.

Witchhunter is right. And this is how you find accuracy, that's more important anyway.
