RYT modified case jig

[Sigfla]

So I just got this thing a while ago to make a modified case for my tight neck .204. I have since made a few cases. It is so easy to use. I have found that using a Hornady lock ring and a small vice helps to lock in the die and keep it from spinning. I would prefer not to use my nice FL sizing dies bc for one you have to remove it from the press and afterwards you have to make sure no shavings are inside it. Luckily I have an extra .204 sizing die I could use. The RYT instructional video is great but I highly suggest you use a lock ring with flats to hold the die. Cinch it down tight with your Allen key after you insert the die into your jig. Also use a vice to hold the flats tight as you drill and tap. I also started using oil while tapping just bc it felt smoother that way and not as gritty. The jig works great and my only suggestion is that they either provide a lock ring with flats for those who don’t use them and/or that they provide some type of universal die with flats to hold the case so you aren’t using your already installed FL die from your press. You will likely need your press to remove the case once drilled but in my case with a turret I could just keep one place open for that purpose.
