Where are my 375 Cheytac guys at?

Shooting the 400gr Lasers and ran out of Retumbo after my last 46 loads. Can’t find retumbo anywhere around me right now so I’ve had my hand forceto RE33. There wasn’t a whole lot of data online for RE33, especially with the heavy 400s. I found some people settling in the 132-138gr range with 350s but was wondering how that translates to 400gr.

Current load is 125gr Retumbo with 400gr lasers.

Anyone using RE33 with the 400gr range boolits?

I haven’t. Is that an app I can get?

US869 may be a good choice for you if you can find it

If you email or call Nikki at Cutting Edge, I garuntee she will hook you up with the data you need on the 400 Lazers. They know exactly what works and what don’t. I’m very familiar with .375s and 400 Lazers, but I’ve only used H50BMG. Good luck!
