I have a 6.5 jdj barrel for my t/c & would like to try boolits in it, what this is is a 225 win case blown out & necked up to 6.5. I normally shoot 120 gr nosler b/t's at 2200 fps with imr 4320. The load data came from ssk with the bbl.
The closest published data I have found is for the 6.5 carcano with a 129 gr boolit & unique.
6.5 jdj case 6.5 carcano
dry wt 147.7 dry wt 152.0
wet wt 188.3 wet wt 200.6
Based on the weight difference, & lymans 8.0 starting load, would it be wise to reduce the starting load by 10% & go from there? This would be using BaBore's 6.5 kurtz, unique, & a cci 200 primer. The barrel has a 1 in 9 twist. Thank you for any & all help.
