.308 Build
Ordered all the pieces from AF today so I can build my .308 Condor. Frame, trigger asembly, power wheel, fore arm grip. I have 28″ barrel and bigbore Blod valve. I will make everything else. Lathe is going to be here around 12:00 tomorrow. Can’t wait to start making things on a real lathe. I will then have .22 .25 and .308. Want to try and break 400 fpe with .308.

What do yo have in mind? Was not a easy task. Frame measures 1.260″ so that piece is cut from solid bar. I’m going to do the other side later. I need to get a tilting vise instead of tilting the head on my mill. I mainly did it so the breech knob has a bigger surface to push on. The acetal bushing I put on the cocking knob was getting hammered and wasn’t lasting. So I went with a .320″ slot instead of a .260″ so the acetal is taller and thicker. Now I need to make a new breech to solve the cocking issue.
😯 Smokin! Condor on steroids!
Very nice,
I just might have to borrow a few of your ideas 🙂
looking good…have you thought about extending that “sheild” / plate all the way back past the valve…so in case something goes wrong the blast is diverted away from your face…i used that on my rifle while messiing with it….heck with your skills you could make the sheild move back and forth with the breech…..
the rifle would still be open to the left side, so easy to load ….could turn out to be a life saver
One of the most impressive builds I’ve seen on this forum. Truly ISB (incredibly super bitchin……). 😀
Your workmanship and workshop are just amazing.
Made a aluminum breech last night and made the plate to strengthen the frame and fix my screw up. I’m having cocking issues and I think it is because the sear notch is not cut deep enough.
Will have to remake the breech and use .070″o ring instead of .103″ just isn’t enough room. Might put 2 .070″ o ring on the hammer side. Gun shot good and I think I can put the valve back in the 62 ci tank. Shot it with the aluminum breech and new knob. Going to lighten the knob by making it hollow and capping it with delrin.
171 gr at 848 fps
118 gr at 957 fps
106 gr at 978 fps
those wolf barrel liners are the way to go…a couple of the guys making highend bigbores for a busines use them (sorry not going to tell who) but they are known for good accuracy, so thats what i would use, they are “thin walled” so would not require any machining to fit (plenty of wall thickness for our purpose”
@Dyotat100 those bushings look nice BUT make sure to counter sink those setscrews or use some other method to make sure the barrel doesnt come flying out….if a slug or somthing decides to get stuck…then something else is going to move…i ruined 1 good barrel on that as it came flying out hit the wall and bend …that sucked !
with your skills i would put a delrin w. teflon liner inside the breech….just because alu doent slide real smooth
It’s mainly to keep air from getting past when shrouded. I will be putting a shroud on it and with the amount of air and pressure I put 2 on each.
doug,
what benefits(if any ) have you seen from o-ringing the barrel bushes?
Yeah. But I’m going to fix it today and you will never know.
brain fart?? looks more like full on diahrrea to me 😛
Nice work Dyotat100, but I have learned to expect nothing less from you.
Turned it in to a side cocker today. Made new longer bushings and a breech out of kevlar reinforced nylon. Everything works great except the breech. I shot about 20 shots and all was good. No more tank dump and I don’t have to preload the hammer spring. I got 887 fps with 150 gr and 856 fps with 171 gr. So Cygnus was right about breech weight. Brass breech and knob was 140 gr and kevlar one was 60 gr with same knob. I weighed the .25 aluminum breech with same knob and it was 90 gr. So if I cut it like the brass one it will be close to kevlar one.
So I decided to pull it apart and change out to a smaller hammer spring so I would have some adjustment. Well that’s when I found that the o ring blew thru where the sear notch was cut. So tomorrow I will make one out of delrin and put a smaller o ring on the hammer side and make one out of aluminum also.
Forgot to mention that I had a little brain fart when cutting the safety notch. Should have been where the marker is.

i understand why you made it and it looks great…what im talking about is making it go all the way back to the bottle collar, so in case you have an oring blowout or the breech jumps off the valve it wont blast you in the face
remember to have a place to lock the breech when loaded and ready to fire…if not when the valve closes it might do it so hard that it pushes the breech off especially if the breech is heavy
i got a video clip of what was happening to mee with a steel breech….i was getting a very nasty blast of air in my face and i had nu clue as to why, until i filmed it in highspeed…then it was clear
