Perhaps this is not a slip fit conical. Some conicals have to be forced down the barrel. If I were getting good accuracy, I think I would overlook the hard loading unless you are taking a hammer and pounding the thing down the barrel.

The other thing is measure the bore of your rifle and then the bullet and see what the relationship is. You might have to get a sizer and take the whole conical down just a little. This might also effect your accuracy.

I bought some maxiball from a person that casts. They looked great until I tried to load them. And as you describe, had to really force them to seat them. They did not shoot all that great so I never really got all that concerned....
