@Enfielder - yet again, I’ve managed to unintentionally ruffle feathers during an attempt to help.
Maybe I’m reading your process incorrectly, so please indulge my explication of my inference here:
You opened the thread saying you have a developed load with Fusions which is highly compressed under the Trophies...
In my first response in this thread, I asked:
I asked this because I inferred one of two things to be true: 1) what I thought less likely - you’re trying to put the Trophy on top of the load developed for the Fusion, or 2) more likely - you’re not getting the speed you want from a load developed for the Trophy itself.
To which you responded, without really answering the question I had asked:
From that statement, I apologize if I incorrectly assumed that my FIRST option above was the case. It sounds like your “pet load” is using the Fusion, and this thread reads like you’re trying to put the Trophy on top of that same charge weight you worked up for the Fusion, without doing load development for the Trophy.
I had hoped that question about velocity would encourage a discussion about the load development you’d done with the Trophy, and hoped you’d share more detail about why you’re needing to compress 4831 - hoping you’d share why you needed to keep pushing into compressed loads, and further share why you weren’t finding anything enticing with a lower charge weight.
I had hoped you would share these details because I’d expect you’d be able to very quickly develop an accurate load with little or no compression under the Trophy bullet, might even exceed the precision of your Fusion load. You seem to know better than to expect the same performance by simply throwing a new bullet on top of a charge weight developed with a different bullet. It just doesn’t work that way - which you acknowledged above - hence my confusion here: you know load development doesn’t transfer between different bullets, but you’re trying to transfer load development between different bullets...?
Did you do load work up under the Trophy and fail to find any suitable accuracy? If so, you didn’t mention that, so I’m left inferring what I can from your words on the screen, and it sounds like you developed a load for one bullet and tried to stick it under another bullet. Maybe how I interpreted that was wrong? Did you do a load work up and fall short on your velocity target, hence pushing more and more into the case, and still not getting your desired speed even with a highly compressed load? If so, again, you didn’t state that effort had been pursued, and didn’t answer what velocity you’re needing.
These are the reasons I asked my first question - what velocity are you trying to reach which H4831 isn’t delivering? From there, the rest of the thread reads like you’re trying to shortcut load development, and seeking different powders without really exploring H4831 under the Trophy - if you HAVE done that work, you didn’t mention it, so I apologize for assuming it wasn’t done.
