Sierra stresses that despite it being in the Gameking line, the bullet is for varmints. I wouldn't hesistate to use the 55 grain HP Sierra Gameking on a deer if I had a steady hold and head or heart shot. There are plenty of better calibers for deer, but many deer have fallen to the 40 grain 22 Hornet. A super long, sleek, VLD bullet with lead core may also not stabilize in that same twist as well.Īnd last but not least.
WEATHERBY VANGUARD SERIAL NUMBER VS FULL
The classic Greenhill formula was for full lead bullets and is barely, marginally, accurate for cup and core bullets for twist vs stability.Ī short stubby heavy bullet will usually stabilize in a slower twist than the book requires for a certain bullet weight a non lead bullet that is much longer than an equal weight lead core bullet may not stabilize in a twist generally associated with that weight bullet. My friend had a Rem 700 in 1:12 that shot 69 gn SMK's just fine as well.Īs has been mentioned in the post the length of the bullet is the issue, not the weight. It was not a full bullet profile going the through the target but consistently a rectangular hole one bullet diameter by two bullet diameters. Accuracy was still acceptable but marginal for what a 223 is capable of, but was not a clean round hole like the 55 gn did. I tried 69 grain Sierra HPBT Matchkings in it just to see where the upper limit was. Caliber or gauge, barrel length, serial numbers, and more. The highest serial I have seen for the S1 is VS 393XXX. What I would like to know is if anybody out there has a late S1 with a serial number that doesn't begin with VS.
It shoots 55 grain Sierra HP Gamekings just fine. When was my Vanguard rifle made Posted Septemby Jacob Solberg & filed under. To help me remember, I think of the VB serial as meaning Vanguard Bar Stock. I have a Win 70 223 rechambered from a 1:14 twist 222.

If you are only planning on using 40-55 grain offerings 1:12 or 1:9 are not an issue.
