I have been following this for a year now. I don’t worry about all the fancy gadgets anymore. I use regular full length dies from Hornady. I resize, prime, load, and go shoot.
This was my last group following this method for my 6 ARC.
I can second kids having a hard time with the Howa mini's. My 8 year old daughter had a hell of time cycling the bolt on my Howa Mini. She couldn't do it from prone. My 12 year old manages it just fine.
