Cutting edge 458 win mad data

[Twisted]

Hello everyone I’m new to the group and hate to ask a question that’s been asked 100 times but I’m new and not really tech savvy. I just bought an unfired Winchester super express in 458 Winchester magnum made in 1981. I ordered some cutting edge 450 grain flat nose bullets and im searching for load data. What I have shows 3.310” as suggested oal and I have H322, 3031, 4064, 748, and other suggested powders. Any help appreciated. I’m going to shoot some hornady 3-350 for plinking and have data for those bullets.

CEB will send you load data if you email them with the request. They've provided me with probably 10 cartridges worth of data and usually within a day or two of emailing them. info@cuttingedgebullets.com

Thank you sir. I will do that.

you might also reach out to @michael458, he has done some serious testing of CEB's in the 458.

He has already reached out and gave me a lot of data to work with. Thank you for the heads up Sir.
