I am just starting on two builds myself... The 300 Whisper round looked like a neat little round. So, I ordered a chamber reamer and headspace gage from PTG at Shot Show. So far, I have made a size/trim die for the Dillon trimmer using the chamber reamer, it works ok for now. It takes 223 brass in, rough sizes and trims the brass to the 300 Whisper profile, but it is still just a tad bit long and still has to be final sized and trimmed to lenth. I am plannig to make a proper size/trim die in the next month, that way I only have the one step. I also had to modify a XL650 toolhead so the trimmer die would work properly, but so far it works like a champ. I found two 24" barrel blanks at the Crossroads show a few weeks ago for $50ea.
The first build is for the AR platform, I cut 11" off the barrel blank and will be turning it down to either 10 or 10.5" overall. The muzzle will be threaded 5/8x24 for a QD YHM Phantom. I have a YHM Diamond Series Spector FF tube, Sun Devil slick side flat top receiver, Mil-spec CTR stock and MOE PG, Young Manufacturing chromed BCG, a Trijicon Reflex 8 min scope and YHM front and rear flip up sights that I'll use to assemble this thing. I haven't decided on the brand of lower that I'll use, but will probably use a Sun Devil lower to match the upper.
The next build is going to be off a Savage 112 host that I picked up cheap just for this build. I am just waiting on the barrel nut wrench so I can take the old 223 barrel off. I'm planning on turning the barrel to 13.5" and permently attaching a YHM QD 308 mount so I don't have to SBR this. I have a 30mm Super Sniper scope sitting on the shelf that is just screaming to be put on this rifle and will match the Choate Super Sniper stock that came with the rifle.
I'm thinking of an ACU camo pattern for both builds to finish them off.
Right now I'm just taking my time till my reloading dies get here. I just ordered a 2 die set of Reddings from Midway but are Backordered.
If everybody wants, I can start another thread showing the progress on the builds, I have taken a few pictures of the work I've done so far on the rifle builds.
