Here's a study that my step-grandfather wrote about Calvinism.

With all due respects to your grandfather, he confuses eternal salvation with gospel salvation and vice-versa in most of his article, and parts of his rebuttals, so I don't think he truly understands Primitive Baptist doctrines, and if he doesn't, then he cannot claim to be an authority on Primitive Baptists, or doctrines.
Also, one woman, Jettie Harper, out of so many primitive baptists, in a primitive baptist
hotbed (your grandfather's description) comes out and wonders how to get saved, and your grandfather thinks Primitive Baptists are misleading people ?
Well,
how do you get saved ?
Is there such a thing as a how, or is it more a Person.
Is it what
she does, or is it what
Somebody else did for her.
What are you going to do with this Scripture: Matthew 7:21-23
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 2
3 And then will I profess unto them ,
I never knew you: depart from me, ye that work iniquity.
So, she can pray the sinner's prayer all she wants, accept Jesus Christ everyday upon waking up and before bed, and in the end, the question is still : Does Christ know her ?
The Father's will is that we believe on Christ when we hear the gospel of our salvation. Not on what we should do, or on what others teach us about how to be saved.
There is no
how to be when it comes to our eternity.
The sinner can rely on only one Person. Not a method. Not a system.
I don't think your grandfather, or Jettie, for that matter, understands that the work of redemption is OVER, unless there is anything in the Bible that says Christ MUST be crucified over and over again for every sinner that repents and accepts Him.
It is over, done, finished, accomplished, and all who are to benefit from His finished work are already benefited. We can argue about grace and works, heaven and hell, doctrine and heresy, all we want until we're blue in the face, nothing will change the fact that Christ is seated in glory, the cross is past, the tomb is empty, and all whose names He wrote in His book of life from the foundation of the world are found, redeemed, and safe.
Your grandfather's article is just another article that purports to refute Primitive Baptists, not Calvinism.
