Perfect, location so I can get the story to tie to the pic TBG was kind enough to post for me.
Basic story
A friend was given a type 99 to "play war" back in the 50s.
Fast forward a ways (2016) he thought since I had always like and shoot the various Arisakas that he would gift it to me.
HECK YEAH, ANY free gun is welcome at my house!
It needed a firing pin, mainspring, and safety. Thanks to good fortune and a great guy on the net I had those in hand post haste and at a reasonable price.

I have a sporterized 99 (7.7X58) so I already had some idea where I wanted to head for load data and shot loads other than those shown.
I have no plans to send a coated bullet down the bore of this stock military 99 though like the spoterised gun I could use 0.308" bullets.

These are not starting loads, but only after some development.
AND
ARE NOT RECOMMENDED LOAD DATA
50 Yards off of front rest, standard military sights
Most horrendous trigger I have ever pulled (future project)
Brass formed from 270 Winchester ( see there is a use for the 270 ;>))
Probably Wolf LP , but may be CCI LR primers
Powder is 10B101 (91A-009)
RCBS 150 FPGC Sized 0.311" 50/50 lube
The numbers on the target are grains of powder.
No velocity measurements available at this time.
If you note for the 16 grain load two, shots 1 and 3 are close together and shot 2 is WAY off. As A hint I can tell ya that one should not try a hold whereby the tip of the thumb is pressed against the sling swivel or barrel band( forget which it was now) . . . It apparently throws the shot off and hurts like he((.

18 shoots very well and really does blow up a gallon jug of water.

As you can see 19 is too much of a good thing.

Looks like the rapid change in group I have found in my 98 with 1 grain increase of 4759 and the GB 175 grainer

Thanx for posting the pic TBG

You are welcome. I think 18 grs looks good and I agree on the .270 jab!

Since posting pics here is several steps above what I can do, IF someone will post them here for discussion, I will email them a pic of some 3 shot 50 yd groups with boolits out of a full military (minus upper handguard) Type 99. I have got to work on the trigger thought it is the worst trigger I have ever pulled, doubt a trigger guage goes that high.
I have no idea of what a 100 yard group would look like because my range here at the house is 50 yds.

One of the easier ways is to open a free account with Tinypic.com. Then you take a picture of what you want to post in a message. You go to Tinypic and upload the photo. After it gets uploaded you copy the link shown for message boards. Then you paste that link into the message. More advanced is to resize the image to be maybe 640x480 or 800x600 in order to make the image memory size smaller.

Did a little work up first with the Sporterized version, but NO accuracy development.

Best loads for the sporterized version so far is ??.? grains of WC 820 (n) and ranch dog at 0.311". See what failing to keep decent records does.

Time for some chrono work no matter which gun/load
