Hello Everyone,
Can anyone tell me if Imr4350 and H4350 be measured the same? I am wanting to load for a 300 winny with 180 grain partitions. I have H4350 on hand and want to try the load data in the Nosler book under Imr4350 without going out to buy a different powder.Thanks

The two powders are listed as similar in the burn rates.....but the idea of substituting is a dangerous thing to get into. The data is free...go get it.
