Barnes 36gr Varmint grenade in 222Rem. or 22-250?

Does anybody use Barnes 36gr Varmint grenade in 222Rem. or 22-250Rem.? I am thinking of trying them in both of mine. My 222Rem. is a Savage 340E with a 1-14" twist and my 22-250Rem. is a 12FV which is 1-12" twist. I would be greatful if anyone had any info on start loads for them since I have not been very fruitful in finding load data. Any info or sources would be wonderful. Thanks in advance!

Edit: I have a wide variety of powders that I currently use so info for any of the following powders is useful. AA2230, Win748, H380, H4895,BL-C(2), Benchmark, Varget, IMR3031, IMR4895, IMR4064, IMR4320, Reloader10x, and Reloader15
