CEB 450gr .458 Solids load data? Also 400gr Woodleigh PP’s

[Certus]

Does anyone have any load data for this bullet? Aiming for around 2000fps

Also about the same velocity with a 400gr Woodleigh PP?

Cartridge is .450 3 1/4” Nitro, rifle is a 1905 vintage. Bore slugged at .4575

You should be using the Bullet CEB makes for the 450NE a .457 dia Bullets in the 489gr Solid and 450gr Raptor ...
This is the combo I shoot in my 1902 Gibbs
I have successfully used RL 15 w/filler, H4350 and H4831 currently loading H4350

Yes I am taking my 450 for buff this summer. Have a great load dialed in with RL 15 with both the 450 solid and 420 Raptor. 81 grain on the Raptor at 2180 & 80 on the solid at 2145. Loaded with about 3/4" long piece of 1/2" backer rod. Start low and work up as I have 3 lots of RL15 and they vary quite a bit.
