I've been practicing with the .45 colts in my .454 casul and I have also shot a couple of boxes of the 300 gr. I love the gun and have become reasonably proficient with the .45 colts. I will admit to some flinching when shooting the heavy loads in it. Any suggestions for overcoming this? Also I need to ask what you guys would recommend for an over the counter round...brand, bullet weight etc. I will most likely wait until I get to Anchorage before I buy them...need suggestions as to where to get them. Thanks
