Re: Anyone ever reverse engineered HSM Trophy Gold ammo?

What's with folks all of a sudden wanting to duplicate mediocrite?

It's a waste of time.

You know they use 168 Bergers.

You can measure the OAL as a starting point. But, you'll likely find something better when you fine tune your seating depth.

You can reload the once fired brass or get some Norma brass which will be even better.

Pick a good powder/primer such as H4831SC with Fed GM215M primers.

Get a reloading manual or go to Hodgdon's website. And, do a proper load workup. My guess is that you'll find a better load within the first 20 shots.

The second 20 shots will confirm. And, you can improve on that down the road.

In the end, you would still have to start low and work up to confirm your observations though.....

In my view a lot more trouble than choosing a powder that is available that meets your criteria and simply working up to accuracy node and calling it done.

I tend to try and use those powders that have decent density and are known to be temperature tolerant.
This is very good advice!
