What's new

Hi, I saw you were looking for some load data for your .280AI - here are a couple spots to check;

Gold medal Muntjac, please excuse toaster

Good morning!
Your question was on point and correct. We're just reluctant to publish too much on an open Public Forum.
Anybody can buy bullets and take measurements. We just don't want to point out what we've learned.
To your question, we've learned that a ratio between 60/40 and 50/50 of nose (HP depth) to shank is the "sweet spot" for performance. This is somewhat dependent upon caliber and also on bullet style. A Lever Hammer's side walls are thicker than a Hammer Hunter, for instance, and the LH's open slower/later than the HHs for instance. "Tinkering" with the hp mouth can change this. Simply chamfering the hp mouth can radically change performance of this bullet.
The new HHTs are a direct offshoot of the LH testing we did, for instance.
There are several other variances that are being tinkered with. The new bands on the HHTs are presenting some challenges as well. The PDR bands are thicker than the old ones and wider as well. This is causing some problems/challenges that will have to be worked out. This specifically is what Farleg has been referencing in some of his posts- he just can't come out and say it

Welcome from Indiana.... where in NM are you? I'm older than dirt and got my first bull elk near Chama in October... going back this year for a cow... had no idea NM was so beautiful..
