So update on the 27 grain bullet problem. Turns out it might have been a range problem(my range looks like a jungle at the moment), there were a few blades of tall grass in front of my target and I believe the bullet was hitting those and starting to tumble. I could be wrong but a fast moving small bullet can be affected by stuff like that. I say that because if I moved higher on the target away from grass, the keyholes stopped. The 36 grain loads did produce a 1in group this weekend so I believe the gun is as good as it is going to get for what it is. Buddies gun built a little different but same basic setup was getting .75 groups with american eagle ammo(40grain). My handloads might need some adjusting or tweaking still.

Well if I had to pin a number to it lets see if I can add it up. I am just a simple Arkansas man so will take my shoes off real quick.

Donor gun= 280
Bolt= 250
Barrel= 470
Trigger= 125
Magazine(yeah you read correct, it is not a bobsled gun, it actually holds ammo and feeds them =-0) Trade for an Timney Arisaka 7.7 trigger so basically free but market value 85 bucks give or take.
Stock/Bottom metal= Freebie
Brake= recycle from old gun
Scope= 300
Rings and base= recycle from old stuff
Machining(headspacing etc..)= practice for me so practically free minus lathe and tool costs that I already owned
Total= 1425..... so not much different than a ps90 and ten times as cool to shoot and look at than a ps90 any day of the week. Unless you count the money I recoup from selling the old parts, brand new 243 barrel, bolt body, bdl stock and x mark trigger, had cheap 3-9x30 simmons scope and rings so maybe 150 bucks resale value for all on a good day? If I could figure out how to post a picture you would see a few of it.

Thanks, hope to get it dialed in really tight soon. Will keep updates coming in as well with handloads, I should be able to get pretty fast.

What magazine did you use? Or where did you get it? I am building a rifle similar and really rather it be a repeater. Thank you

I had help from a buddy to build a custom follower on a mill from aluminum. The magazine we used was a standard AI style mag with removable insert. I believe I got it from Midway. As far as the insert that is just a shoot from the hip and see what works with your rifle. It might take a couple of tries.

So I think the magic weight for the bolt gun is 40 grain (used factory AE and had good results). Granted I only got 65 yards to plink with on the range it still holds a pretty good group. I averaged 2095 FPS with factory loads. Got some pull down 40 grainers coming from EA so may be able to load up some and get a few hundred more FPS.[img2=]Image[img2=]Image[/img2][/img2][/img2]
