If you have a rifle that you have to "pound" the sabot down the bore, then that is not the sabot/bullet combination for you. That is when you look into a thinner sabot or difference projectile all together..
Exactly, it took a bit of tinkering but I eventually found a bullet that loads well without me popping a vein in the process. Now, if someone is complaining about hard loading and then not wanting to take the time to tinker to find what works best for their barrel, yes that's laziness.
