22 BR load data Vit

[kaduflyer]

Looking for some load data using either vit140 or Vit 133 in my 22br using either 52 or 55 gr bullets thanks

See if this helps. Give me more details on your rifle, OAL, bullet, etc and I can further tune the data. I loaded VV N140 this week for my .22 BR but it is 8 twist and set up for 540 yards.

I am using a 12 twist 24” barrel the h2o case capacity is 37.2 grains using a Hornady 55 vmax at 2.080 oal and would like to try 52gr Sierra but need to find oal for these thanks

Let me know what you learn. I have two well worn 22 BR rifles. One is waiting for Bartlein to finish a new tube for it. The other is in service shooting Berger 70 VLD Tangent. I am switching to 73gr Berger (which is a secant that looks like a Sierra) this week at the range. I shot two groups under 2 inches at 540 yards at 540 yards last week with the 70s. The secants give me more bullet under neck tension and more the worn barrel can grip in the lands.

They both came out as 55 vmax nothing for sierras
