Thanks to raamw I have a stock of the Barnes 450s at less than $0.25 each. These will be practice, plinking and deer bullets in my 458 Lott. Maybe DG bullets too, if I can decide between them and the 420 grain CEBs.

So using Hodgdon's 60% rule for H4895, and 458 Win Mag data I want to make some fairly stiff 45-70-450 loads, maybe 1800 fps?

Does anyone know, what velocity will open the 450 TSX? I have heard that 1800 fps will get them somewhat open. I also know that the 458 hole is probably enough for deer all by itself.

I will crimp, using the Lee FCD die, right at the top of the top groove in the bullets. This is what I need to fit my mag box. Any tips on the Win Mag or Lott and reduced loads?

Thanks,

Sorry, wrong forum.

I used some in a 45-70 once many years ago; all they did was peel back the petals about 1/8th inch. Not going 1800 fps though.
Gave up on them.
