First successful hunt for the 35 INDY

Sir,
I have picked up what I was told was .358 INDY.
Nice little Handi Rifle. My questions Is about using 35 REM load data . I would like to load using a 358315 cast bullet.
What do think about using 35 Rem load data for the .358 INDY? I have developed a load for 160 grain pistol bullets that are 2 moa at 100 yards. That is max distance for this combination. I would like to see if I can work up a load using Gas checked , powder coated 210 grain 358311 projectiles.
Also every time I run the load data for 358 Hoosier. I find it to be at or above 35 Rem + P . Some in the unsafe zone.
It seems to me that using 308 cases will offset the 6% difference in case length of a 35 Rem.
Could we not use all 35 Rem load data?

To the best of my knowledge, I am the only person who has made a "35 INDY", which is 303 British brass that has been turned to create cases with the external dimensions of a 35 Remington.

I wouldn't be surprised if others have done the same thing, but I have never run into another person who has. The ".358 INDY" is not a round I'm familiar with, so I can't really speculate on it. The 358 Hoosier is based on a different parent case, but can't be much different, in terms of case capacity or performance.

I haven't done a lot with gas-checked hard-cast bullets, but I know from friends of mine that they can be very effective. The load data for them is not the same as data used for jacketed bullets.

Did the rifle you bought come with reloading dies and at least a few pieces of fired brass? What are the details of this round? What is the parent case and dimensions? Do you happen to know the case capacity, in water?
