400 fps bolt action.

I used Google for a bit last night on the topic of 400fps bolty's and I'd see a link to what I thought would answer my question only to find many people thinking someone was insane for wanting a 400fps bolt action.

I have experience, even though it was years ago, with VSR 10's and Bar10, plus KJW gas rifles. A little bit of experience with ASP2's, but more with VSR platforms. The thing is, back when I was into bolty's,
I was building 500-550 fps rifles. Those requiring reinforce everything...

Guess what I have in mind is buying a BAR10 G-spec...not really sure a TM VSR 10 is worth the money for a 400fps build.
Possibly buy the TM hop up chamber with stock barrel. I know a local player with a TM Gspec and he left the stock hop up and barrel in and it's very accurate. Far better quality than JG hop up chamber and brass barrel.

Would I need any reinforced trigger sears? Upgrading the cylinder set required at all? Anything I should keep in mind when building a 400fps bolt action sniper rifle? Would I need a new spring? I believe JG's shoot a bit higher than TM's


I'm really looking for something that can hit a coke can at 150ft fairly easy and not make much noise. I know my KJW M700 was insanely quiet, but I do not want to go the gas route again.

I ended up selling off all my bolt action guns because I was building them to be 300ft bb shooters and I play in some dense woods, so I seldom used them. Just came to me that a 400fps (((NO MED))) bolt action rifle would be a lot of fun and ideal for me to use on certain fields I play at locally.

Any insight and thoughts would be appreciated.

thanks...


the conceited part - just amazed I can still run around on the field at my age. ;)
Still pumped after a damn near perfect game and multiple successful ambushes...
I'll calm down in a couple days and come back down to earth.
Apologize for coming across like I'm full of myself.

Its pretty much customary that over 450Fps you upgrade the sears, so for 400 I see no need.

I would personaly upgrade the cylinder and cylinder head, to increase compression, as well as the spring guide(you can never be to careful).


I havn't had any experience with TM stock chambers, bucking, and barrels; but if your keen on getting those instead of going for a Nine ball bucking and EdGi or like barrel then go for it, but again I don't know how stock TM components perform.
Thank You! What I was pretty much after and needed to know.
