Barnes 53 Gr TSX

I picked some of these up to "round out" an order. I was thinking of loading them in a 22-250. I have read where these bullets don't produce the pressures a normal bullet would due to the all copper construction. What would be a good starting point for varget or h380 or h414? At what point should I stop, considering the lower pressure of the cartridge?

I just recently worked up a load for the 45 grain TSX and Varget in my .22-250. Started out at the minimum and worked my way up to 1.5 grains below max before I ran out of time before my hunt. The groups were the tightest at the 37 grains(highpoint so far) that I stopped at, so I am looking forward to slowly going a little higher to see if the groups get a little tighter even. I am using magnum primers in my loads so I will probably stay at least .5 grain below the max even if I have zero signs of pressure.
