There is an effect something like detonation that has been known to destroy magnum cartridge chambered rifles that have been very underloaded.
The process goes something like this:
The primer ignites correctly but it's flash is somewhat dissipated in the empty space in the case. There is enough flash to burn off the deterrent coating on the powder but not enough flash to maintain smooth continuity of combustion over the whole surfaces of the propellant but nonetheless there is still some combustion. What happens is the propellent then detonates because there is no deterrent left to moderate the speed of ignition.
The answer is to use a magnum for what it was intended for.
Don't go below any reputably published minimum load.
If you really need or want something that has recoil performance like a 223 or 243 then entertain those as an option.

I think I have a bit of a plan now what I will do is find some 150gr Nos part pills and load a minimum load using 55gr of AR2209.
fit it with a good recoil pad to it and add a bit of weigh to the stock.
That load will be around 2781fps
Going by a recoil calculator with a 8lb rifle the recoil will be 18.99 ftlbf
What do you all think?
