Using H4350.

Probably being over-cautious, but as the Barnes PDF doesn't mention H4350 for the 120gr all-copper bullet, I wondered if anyone has experience of it and my preferred powder (I have plenty of tubs) in this chambering?

I'm mindful to start with 36grns as the 127gr does mention H4350:

Hornady app for the 120grn cx Use at your own risk.
Using the same bullet in the same cal over ramshot hunter and getting 2806 fps av
 
@Klenchblaize worth noting it’s been one of the harder Barnes bullets I’ve used. I’ve only got 2000fps out to 375 yards, I know that’s plenty far for the majority of shots, but I wouldn’t be using this unless I could get mv of over 2700fps, depending on barrel length you may struggle with 4350.
 
More interested, in the first instance, in how they will group at 100-yards. Thereafter in-the-field performance on woodland fallow at considerably less than 100-yards!

I have tried both bullets in 6.5x55 and .260 rem. Both will shoot 3 round groups into an inch but 5 rounds tends to spoil it. I use RS 60 for both (not shown on the Barnes data but run through Quickload to check they are safe) I think they are both ok out to 200 yards or so.
