The one time I would take a Synthetic is with the recoil cushion TC makes it works well for me on certain guns with a 140 grain BH load which it shoots with minute of angle accuracy. I only wonder if this is an idiosyncrasy of my Endeavor or if all the Endeavors prefer that heavy a load with certain bullets because there are some like the 250 Deep Curl with shoot quite well with 110 or some with 120 grains.
