If you guys are interested in jacket thickness or contruction, I did this for the Savage ML guys awhile back and with velocities being close to the same, figure it would appy the the 450 also. http://dougsmessageboards.proboards.com ... 735&page=1
I'll hopefully be joing the 450 ranks by end of summer.

Pardon the poor machining, deburring, and pics, but from left to right,
250gr SST Flex Tip, 250gr SW, and 300gr Bonded SW. As you can see, they are of identical construction for the most part, (the 300gr SST/SW's are the same as the 300gr Bonded SW also). Base thickness is .050, sidewall .035 just below the ojive. Dunno what it is with tipped bullets, but darn near everyone I've cut has had a void in the tip.
275gr ringed Parker, (Bob added 3 rings for some testing I want to do sabotless). Base thickness is .030, sidewall .021.
325gr .458 Hornady Flex Tip, base thickness .050, sidewall .040 just under the cannuler where the interlock is. The wad of copper on the right side of the tip, is one of the heavy scallops folds they add to the nose for expansion, and me not having it squared up right in the vise.
Below Left to right
250gr .452 XTP, base thickness .025, sidewall .025, this bullet is canted a little in the pic (and not deburred so well), making the sidwall look thicker, but it's .025. (300gr version is the same construction but with a extra cannuler)
240gr .452 XTP mag, base thickness .050, sidewall .040 (300gr version is of the same construction also, no wonder these are tuff lil suckers)
300gr .451 Speer Unicore, plating thickness is .015 all around.
300gr .451 Speer Gold Dot, plating thickness is .035 all around. The copper dot centered across the cannuler, is the bottom of the Gold Dot. These were intened for the 454 Cassul, there were some expansion pics posted on the MM board awhile back, pretty impressive. http://www.modernmuzzleloader.com/phpBB ... t=gold+dot
300gr .458 Speer Unicore, plating thickness .022 all around.
