I continue to search for reliable data but can only find loads listed on other forums, I am not saying they are unreliable, but I am aware different primers and case and jacket thicknesses can vary the pressure. Thank you for the words of caution.

I started using fast burning surplus pistol powders with jacketed bullets many moons ago when our club started the MBBR competition. Back then guys were using either conventional cast bullet loads or full power jacketed loads. I was dissatisfied with the occasional flyers I was getting with cast loads and didn’t care for the beating I would get when shooting 60-70 full power jacketed loads thru my 03’s. On a whim I loaded (10) rounds:20 grains of H-108, 168 grain Sierra MK, standard LRP in LC brass and shot it thru my well worn NRA sporter. It held the ten ring of the match target. There were no warning signs and it was pleasant to shoot.I eventually settled on 21.2 grains of H108.My shooting buddy started using the same load and began winning matches (group/score) immediately. Now nearly all our club members are using some variation of the load. Since H-108 is long gone, AA#9 or 2400 are being subsistuted.I have found 4227 to be most accurate in my guns. As I stated, the load does not produce enough pressure to require full length sizing of the brass. I’m neck sizing only. Bullets are seated to engage the rifling.
FYI: there were a lot of raised eye brows when I started using these loads.I wasn’t offended nor was I trying to convince anyone. They were developed for my use only. As with any loads proceed with caution.

Regards,
Ken


I’ll be dipped! Here is load data for .308 reduced loads using some of the powders I mention. Bullet used is a 150 JSP.

Thanks Stan,

I guess Sgt. York wore out the original barrel on his 03. Pic’s show a 5-44 HS barrel.

Regards,
Ken
