Thread: Load reductions with Hodgdon PSI data in the .223

Greetings All,
Some of this has been covered in another thread on 77 grain projectiles but I thought it was important enough to have a thread of its own so here goes.
Some will have noted the substantial reductions in charge weights in the new PSI data for the .223. I was working with the 60 grain Hornady V-MAX projectile and loaded 25.0 grains of AR2206H (H4895) which produced 3,145 fps in my 26" barrel. 26 grains is listed as Max but needed more compression than I was prepared to use. Hodgdon velocity for the 25.0 grain load calculates to around 3,100 fps in my length barrel so all good.
The new PSI data topped out at 23.7 grains of H4895 for 3,084 fps with the 60 grain. That is below the CUP start load of 24 grains for 2,918 fps. Something is decidedly screwy here. Slightly less powder for 166 fps more velocity. That would be nice. I had run into the same problem with the 60 grain and BM8208 with the Max of 23.6 grains producing only 2,940 fps rather than the claimed 3,057 fps claimed in spite of a 26" barrel and heavy cases.
It looks to me that The PSI pressure barrels may be much tighter than the old CUP ones. This added to the lower 55,000 PSI pressure has resulted some pretty light load data for this cartridge.
I use the Hodgdons data as it is specific for a projectile and it states the pressures (plus it is free) so am working through how to manage the new data so what is everybody else doing?
