Thank you for the compliment. Never thought about entering a challenge. I shoot to beat my own results, always trying to improve my technique and better my last results. I probably could match or better with my 204R with some additional load work. http://i993.photobucket.com/albums/af56/rbp71854/Bla...

I have some experience with a 20 Practical BHW barrel. I think you would be happy with your choice. I really haven't had the time to fully develop the best loads for this set-up. Hope to finish up other projects this fall and finish load development on the 20 Practical this winter. http://i993.photo...

When I was considering a 223 based .20cal as a companion of my .204 Ruger upper I went with a 20 Practical upper. Simple 2 step neck down process of new .223 brass, thereafter no special resizing necessary. I normally shoot 5 shot strings with ASC SS mags and have not had a reliability or feeding pr...

Thank you RBP. The ASC magazines, are these the brand you use with your 204? Do they work & function well? I need to buy some 20 rounders but haven't decided which to buy yet. Thanks, JD Southeast Texas I use the ASC SS 5 round mags. They have the longest OAL that I have found and they have bee...

Have similar barrel and lower. I seat based on ogive of particular bullet to barrel using Hornady modified case and comparator. Here are my results for my particular barrel from my cookbook. Seat the bullet Seat type/weight bullet to Ogive of the rifle's chamber. Measured by Hornday OAL gauge and Co...

AR barreled Shilen 24" 1-9" Have also had good precision with 26gr Barnes HP. http://i993.photobucket.com/albums/af56/rbp71854/BlackRain_204-Ruger_08-13-2014_Sierra-32gr-Blitzking-RL10X-1_zpsf46dde77.jpg http://i993.photobucket.com/albums/af56/rbp71854/BlackRain_204-Ruger_04-09-2014_Sierra...

I am in the initial stages of finding the right RL10X loads for my 1-9" Shilen barreled Black Rain Ordnance. For the Barnes 26GR Varmint Grenade 24.0gr of RL10X seems to be the best. 5 round groups at 100Yds. http://i993.photobucket.com/albums/af56/rbp71854/BlackRain_204-Ruger_06-12-2014_Barnes...

Thanks Ric.

Great information and completely answers the basic question and I imagine potential future questions I might have had. I have recently begun reloading again after a 40 yr plus hiatus and find that I have forgotten more than I presently know.

I can't seem to find the recommended minimum neck wall thickness when .204 brass should be dumped into the recycle bin.
