I am looking to try a load LeHigh Defense 142 Gn Controlled Chaos bullets for my Borden actioned 7x57, 8.5" Twist, 22" barrel length.

There is nothing on the Lehigh website by way of load data, just a statement that if there is no data shown, then there is no data. Really Helpful ... NOT.

I shall be very grateful if anyone here has gone down this rabbit hole for the 7x57 and is able to share experience. I realise the inherent danger of copying load data, but a starter would be much appreciated.

You could use similar weight data to start.


Don't ask me about my military service or heroic acts...most of it is untrue.

Good Plan..... I've got loads for Peregrine 140 Gn that are good, so I'll try something based on that. Start slow and work up. There is no information on optimal seating depths on the Lehigh site, so I'll go with the monolithic 'standard' starting jump at 100 thou off the lands and see what that gives. I'm not optimistic given the paucity of manufacturers data but..... worth a try.
