Thread: 280ai powder choices

Yet to fine tune my final load. All the research I did suggested the 280ai required a 24-26" barrel to get a full powder burn and it works best at maximum pressure and barrel length below 24" negates and advantages of the Ackley improved case. With a 20" barrel you mat require a faster burn rate powder to achieve a full powder burn, 2209, RL19 or maybe 2213SC. As previously stated Kiwi Greg would be worth contacting.

Slightly off topic but where you getting your Norma bondstrike ?

Hi dannyb, Greg at Custom Guns in Invercargill had some about a year ago, haven't seen anymore advertised anywhere for ages.
