In my case the “need” to load it “long” is being driven by the powder I am trying to use. It is slow-burning and bulky, and at the cartridge lengths the bullet was designed to run at (much shorter than SAAMI max), velocity will be on the low end. No particular reason I should care, but just seems right that I should try the sports car flat out on the open track and not just putter around in town. Most likely your standard load will work perfectly as long as the loaded cartridges plunk for you. If you find that it won’t, you’ll just need a shorter seating depth and a little less powder. Hodgdon and VV provide specific load data for it, maybe some others.Any load data specific to HAP bullet?
Why trying to load so long?
Just curious
I dont load for any specific rules/level or load in any large quantities so basic load data has worked for me.
i have hap and xtp bullets sitting on the back of the shelf so some day I will need some good info.
I got my test loads ready. 5.2 to 6.0 grains by 0.2gr increments of N350 at a COAL of 1.125”. Will hopefully chrono them this week.
