Berger 140 grain Hybrid Twist rate

[Drewdemon]

I wanted to try new bullets for my RPR (1:8). There is a lot of great write-ups about the Berger 130 and 140 grain hybrids. I went on their site and read the 140 grain requires a 1:8 twist rate. Perfect, i ordered them instead of the 130g because they require a higher twist rate. My order came in today and on the box of 140g bullets it says "1:9 minimum". The box has the same part number (26414) as Berger's site?

Should i try them out anyway, email Berger, or return the box? (Berger)

Thanks

Are you worried they won't work in your barrel? If so, don't be. Your barrel has a more aggressive twist than the minimum twist required. Your rifling completes one revolution in 8" of bore. A 9 twist is a less aggressive rate. You can always shoot bullets that have a slower required twist than you have (higher number), but its not a good idea to go too far the other way or you might experience stability issues. Hope that helps.

You need to read up on the word “minimum” in the context of a requirement.

They’ll do fine in that rifle.
I shoot them from a ruger Hawkeye & bergara with a Wilson barrel. Both 8 twist and with 42.8gr h4350, cci 450 primers, seared at 2.2290, they shoot .25” groups out of both rifles.
3/4” groups at 300 easy

Apparently I have to do some reading
