If you can, snap them up. I use them in .224 and 6mm and they work out way cheaper than 100 packs of V-Max, like a fraction of the price. To be honest, last time I bought them in .224 I was ****ed off I didn't buy more as I go through them at a rate of knots.
Performance etc is identical to V-Max. I was shooting hares way out there last night with 50gr Zombie killers.
