CMP sent an email last week advertising cases of new production 22LR standard velocity made by Eley. 10 bricks (5000 rounds) for $355 including shipping. I never used to buy standard velocity 22 until I bought my silencer, so all of my hoarded supply is high velocity, and I only started buying standard velocity after the 22 panic. Given that the best price I've been paying for CCI standard vel is $39/brick, I figured it would be a relatively low risk investment to order a case.
