Hornady 50gr. Vmax loads with Benchmark

[blueridgeMTNs]

I looked around the internet and cannot find loads for the 223Rem (.224) with Hornady Vmax bullet with Benchmark powder. I have Varget, H335, Imr4895, H322 on hand. I would appreciate if those who have tried Varget/Benchmark to post loads. Should I use loads from the next weight in the lineup like 52/53gr Hornady bullets as starting loads? I rather stay with what has been tested but these are no where to be found for 50grVmax and Benchmark.

While we are on the subject I saw Sierra 52 HP match and Sierra says it does not recommend this for hunting applications. Has anyone use the match for varmint hunting?

Thanks!
