The Ramshot reloading manual, which I think is dated 7-2-13 (July 2? Feb 7?) has a set of very helpful reloading data for the 450 Bushmaster cartridge. The data tables include pressure measurements, something Hornady does not furnish with its handbooks.
Data are included for these powders:
- Accurate No. 9
- Accurate 4100
- Accurate 5744
- Accurate 1680
- Ramshot Enforcer
Bullets listed include:
- 200 gr Hornady FTX
- 200 gr Sierra FPJ
- 225 gr Hornady FTX
- 230 gr Sierra FMJ
- 250 gr Nosler HP
- 300 gr Hornady XTP
- 325 gr Barnes Buster
The tables include starting loads & velocities, and max loads with pressures and velocities for most combinations of powder and bullet.
Test environment: Barrel: 16â€; Twist: 1-24â€; Primer: WIN WSR; Bullet Diameter: 0.451â€; Case: Hornady; Max Case Length: 1.700â€; Trim Length: 1.695".
The manual can be read or downloaded as a pdf file from the Ramshot website: http://www.ramshot.com . The list of loading data for the 450B is on page 53.
I think the data are really helpful. Thanks, Ramshot/Accurate.
