Barnes's Tests Prove Why Berger Hunting VLDs Are So Successful By Eric Stecker

[joe0121]

All I know is I cant wait for my win mag to get done at the smith so I can try out my 210 gr loads on some paper. of course I got the "match' bullets that say clearly on the pack my tube is a 1-10 twist and Berger "recommends" 1-11 or faster. Well see at 26 inches I don't see how it will have any issue stabilizing a 210 gr pill unles VLD's need a faster twist? Not to hi-jack but this is a thread worth being bumped. I also notice the two packs I got were slightly different shades of yellow is this done on purpose to distinguish between lots?

The 30 cal 210 gr VLD will shoot well in a 10" twist. The difference in yellow between the boxes is not deliberate. Check the lot number on the box. If the numbers are the same the bullets are too.

Joe,

Good luck with the win mag. My guess is you will be fine with your 1-10 twist.

A 1:10 twist is faster than 1:11. You'll be fine with the 1:10 twist.

Different lots that's why I asked.

I posted that half awake on my way out the door to work. About halfway to work I realized how dumb it was.

Joe0121,

There will be slight differences from lot to lot. The most common differences are in the OAL and the base to ogive measurement. This difference will be very small and should not influence performance but with all components you should confirm your tune when you switch lots.

Something to keep in mind is that we use one die and the same die for each bullet (until it wears out) so even though there are some slight differences from lot to lot the shape of the nose will be the same. This means that if you don't change your bullet seated die you will be in the same place in relation to the rifling since your plunger contacts the nose not the tip.

Having said this, it is always smart to double check your seating depth to confirm that it is the same with each new lot. We only change dies when they wear out so the vast majority of the lots will be the same but it is a good double check to confirm nothing has changed.
