Shrink is correct, there wasn't any discussion about compression... Suggest you get Wolf's book on loading for TDs as previously mentioned. The topic of compression is well covered there, particularly as it relates to duplicating loads with the 1873 bullet (which your Lee bullet replicates). I use a slightly different approach to loading match loads for TDs but follow Wolf's compression method because it works extremely well with original TDs. Of course I follow Wolf's method for duplicating the service loads as there's no sense in trying to reinvent the wheel, especially when this one is already round.
Also if you haven't got dies yet I suggest you get the Lee 5 die set from Mrs Wolf and specify the .458 expander. This die set also contains a compression die. I recommend the Lyman "short" .45 cal neck size die if you want to try my method for match loads.
As with Wolf I also have found the use of a drop tube to be of no benifit when using loads of 70 gr or less and compressing with a die (or the bullet)before seating bullets. However, again as with Wolf, with either the M1873, M1882 or the M1886 Carbine loads either 59 gr FFG ro 53 gr FFFG the bullet can be seated to correct depth compressing the powder. This will not deform the bullet even if cast as soft as 1-40. But if you increase the charge from there upwards to 70 gr for the M1873 rifle cartridge or my match load then a compressin die is required. The method using an upside down drill bit in a press as Shrink mentions works well as an alternative to a compression die.

I think your original thread kinda got hijacked, that happens with these guys. Firmly held opinions based on personal experience, guys who would be great friends when they meet and shake hands get all worked up on the internet. Ah, well, we all learn something when they do.
Anyway, on compressing powder. Don't try to do it when seating your bullet, you will deform your bullet. It is a separate operation. You can get a die to do it from Buffalo Arms, I use my drill press and an appropriate drill bit mounted upside down. Some use a brass rod, others have talked of vibration. However you do it, you want a repeatable and measurable process. Experienced shooters claim (almost all ot them!) that Goex requires more compression than Swiss, with Swiss wanting none or almost none.
Rednck, you wanna jump in here and elucidate this point? You can do it much better than I. I just noticed that it was missing in the previous thread.[/quote]
