Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Type 99 bullets test at 500 yards...Range Report

#1 Post by Rapidrob » Sat Jul 13, 2019 11:41 pm

Having shot my rifle with my match loads at 800 yards, I knew the rifle was a great shooter.
I have three types and sizes/weights of bullets I wanted to try at 500 yards. Two are pulled Russian and one a Hornandy hunting bullet.
The powder used was IMR-7383 also known as RAD-78. It is a surplus powder used in the .50 Spotting Cartridge. It still can be had in 8 pound jugs at a bargain price.
It is not a .50 BMG powder and would be dangerous to use it as such. It is a triple base powder that can be use in 90% of all centerfire rifle cartridges.
It is about as fast as IMR-4831 but has more energy per grain with a heavier bullet. It can tolerate mild compression.
The first bullet is the Russian 7.62x54R 150 grain steel core Spitzer boat tail. This bullet measures .310. It is .001 smaller than the rifle bore of .311.
The bullet shot well and averaged 80% hits. The load was a full case of powder. Recoil felt normal, report was normal. No unburned powder,no pressure signs.
The 2ND bullet was also a Russian bullet,a Yellow tip Heavy Ball,Steel core 208 grains and .311 in diameter. A full case of powder. This round was max safe load. No pressure signs at all.
Recoil was stout, report much louder. The round is very accurate as in fours rounds almost touching on the target and one out of the group but still on target.
This load gave 100% hits. The steel core pock-marked the AR550 steel target.
The third bullet was the Hornandy SPFB 174 grain hunting bullet made for the .303 cartridge. .312 in diameter. The bullet flew well but was the worst in accuracy.
Hits were only 50%. Report was also louder,recoil was normal. No pressure signs. The poorer results were due to the bullet construction, not it's shape. It would not fly straight every time.
No bullet fouled the bore. There was little powder residue in the fired bore. The flip up sight was used and the lowest setting used. A six o'clock hold was needed as all bullets flew high at 500 yards.

Details on the type 99 used? Long, short? Early, mid last ditch?

Mine is the Standard rifle. I bet the long barrel version is a fine shooter.You learn something new each day.

I have never seen a Hornady .312 180 grain sp bullet . I am pretty sure they do not make one . What rifle and bullet were you actually using ?

I have been using IMR 4895 42.5 gr with 174 BTHP Hornady bullets. Had excellent results at 500 meters on steel ram.Shoots well out of my Toyo Kogyo and Kokura Type 99s. Forget which series the are have to dig them out.

On aside note Rapidrob, used your load for 6.5x55 in both M96 and M38 rifles with outstanding results. Thanks!

Your very welcome for the loads. I just finished a long range load for the 6.5x50 Jap, 8x56R and this weekend, the 6.5 MS for the 1907 Geek Mannlicher rifle.
