How accurate is it with the factory load? Is it MOA or Sub-MOA at 100 yards?
If not, then I would go straight to the FAQs and Help threads/articles that appear at the top of this forum.
If it does shoot factory MOA or better, many folks here will tell you to stop right there regarding any modifications, you can bank on the factory load when you need it, and try handloads that match the factory round.
I would try handloads that duplicate the factory load first. If you get the accuracy you need from those handloads, then I personally would call it a wrap with basic handload development. After that, you get to play with different bullets and powders if you want, many folks here would not bother once they have it dialed in with a particular bullet and powder. But half the fun in reloading is trying different things isn't it?
