.310 Cadet handloads at 200 meters off-hand

I'm holding a 200 meter Off-hand match this month. I will be using an as issued .310 Cadet training rifle. I hand about 100 rounds of loads I tried and did not like the results and wanted to get rid of.
I also had 20 rounds of a new load I wanted to try.
For giggles I brought a third Cadet in military configuration but in .218 BEE.
The two original .310 Cadet rifles are as issued with perfect bores. None have been converted to .32-20. Only one will be used for the match.
Three bullet types were used. Two are RCBS 120-130 grain cast, and the last is the 130 grain heeled bullet.
All bullets were sized t o.323 and either pressure lubed or dipped lubed.
The first target is the heeled 130 grain bullet being pushed by 8 grains of IMR-4227. This load is very close to original ballistics and struck at the point of aim.
The group is good.I could have done better but needed to fire off the other 80 rounds and rushed my shots.

The 2ND target was the Hodge-podge of many different powder types and loads. Still most loads were able to hit the target with most shots.
I was able to recover one of the missed shots made with the heeled bullet. The rifling marks are well engraved in the bullet with no blow-by.

With a bullet that fits the bore properly, these rifles can be very accurate. They are easy to shoot accurately.The sights are first rate.The trigger pull has no creep.
Shooting the two .310's with 100 rounds in an hour got both barrels very hot ( 50 rounds each), but the zero did not wander.
The bullet flying in 5 MPH wind was effected a little at 200 meters. Flight time was about one second.
If I hit the target ( AR550 steel) the bullet disintegrated and the impact could be clearly heard.
The .218 Bee Cadet was shooting my handload using a 55 grain gas checked spitzer bullet sized to .224. The barrel has a 1:14 twist. Estimated MV was 2,60 FPS with 10 grains of IMR-4227. I could go as high as 13 grains.
No leading of the bore was noted.
Accuracy off-hand was 2 MOA. My spotter said I was shooting 4" groups. I really need to try this at the prone.
I let the club members fire all three rifles and they all wanted to take them home with them. I can see that.
I have been shooting my one Martini Cadet .310 rifle for 58 years now. It will be with me until I'm gone from this world. They really are outstanding little rifles.

I hope I can do half that well with mine.
I loaded 10 rounds and just need to get to the range.

I went to the range again today. Using the 130 grain heeled bullet this time 45 Alox / 45 Johnson Paste Wax / 10 Odorless Mineral Spirits and bullets coated by shaking in a coffee tin.
10 grains of IMR-4227.
Amazing accuracy at 200 meters. No leading

I am using the rifle for the match next Saturday. The little rifle is just so accurate and easy to shoot 200 meters is just too easy to do.

UPDATE:
I won the match using the Cadet rifle. Lots of "Hang-Dog faces as they got beaten by a "Bot Scout Rifle" at 200 meters off hand!
I love this little rifle.
130 grain heeled bullet .323
Tumble lubed- 45% Alox-45% Johnson Paste Wax-10% Odorless Mineral Spirits, air dry for 24 hours ( lube was liquefied in microwave oven for 45 seconds)
10 grains IMR-4227. I found this non-max load gave the best accuracy at ant distance.
Winchester SR primer
