I'd like to see what everyone's answers are for the most overlooked part of a rifle build. Personally, I've seen far too many gun owners connect good optics to a good rifle with blister pack scope rings. What else have you folks seen that makes you shake your head?
IMO, the #1 most overlooked part of a rifle build is setting up proper throat lengths!
It’s pretty simple, if you have tight mag constraints, pick the longest/highest B.C. bullet that your barrel twist rate can handle, then seat that bullet in a dummy round with an OAL .050” shorter than mag length.
Even if you don’t plan to shoot that particular bullet, have the ‘smith cut the throat off that dummy anyway. Trust me here..
This will give you room to grow as the throat erodes, if that’s your thing. It’s not mine, but .050” short does nice things for reliable feeding.
Still, you will be able to reach the land while staying within mag constraints with everything else that your twist rate can handle. That’s right, everything else!!
If you don’t have mag limitations, simply pick the longest, highest B.C. bullet available that will run in your twist rate, then make up a dummy for the ‘smith with the bullet seated to where the top of the boat tail is even with the neck shoulder junction. This is “nirvana” for the guy trying to get the most out of a rifle without 32 trick moves and/or hindered performance from bullets taking up powder space.
So simple but almost always overlooked…
