Safest big bore

[Sean]

What are the safest design big bore pcp? What design features make a safe gun? My concern is mainly with bolt/probe securement in the breech block. I have nightmares about one blowing out the back of the breech and poking me in the face.i want overbuilt in this area. Silly concern? I ponder about the quality of materials of the more affordable options out there. Aluminum billet or casting and such?? Any one else think about that.i don't hear about many issues like that. Any thoughts welcome.

 Side lever safer than straight bolt designs.

XP Airguns the back of the breech is solid so the bolt shouldn't be able to blow back through it.

airforce guns seem to be fairly safe. especially with the auto safety thing that is a love hate with me.
I suppose it could blow back and explode the bottle we use for a cheek weld. Not much of a fan of that but you'd only feel it for
a thousands of a second.

I kinda think about that with my talon p and the plastic breech cocking knob going to replace with aluminum soon.

Look at all the "budget" bolt action powder burners out there.
40,000+ PSI for many cartridges.
I think this a non-issue

It's not the pure "force" that you need to worry about, as Wendell points out, that is easy to design for.... The danger is an accidental firing with the bolt not locked down fully.... Lloyd did some testing a couple of years ago and it was surprising how much energy an unlatched bolt achieves accelerating back an inch or so.... If it stops suddenly, the force required to do so can be several tons, enough to shear a quite significant piece of steel.... Of course if if doesn't stop, then it comes out the back with considerable energy.... This is probably the biggest factor overlooked in big bore airgun design....

I think about that on my big bore builds. I use cross bolts. Like a Girandoni or a Umerex Hammer. They don’t use an axial bolt. And I have avoided bullpups for these builds, to keep the bolt forward of my head. During some experiments a couple of years ago I used a 3D printed cross bolt with a thin section that blew out the side. Fortunately it was ahead of my face.

 I wonder how Huben's hammerless action would work on big bore scale

Yes. Check out the Rattler

 Well I found out my Piledriver is not safe to deer

[JPSAXNC]

The amount of push back on the bolt will depend on the crossectional area of the bolt, ahead of the o-ring sealing the breech or the bolt probe.

[JPSAXNC]

The safest design would be no bolt. Just a sliding block fed in from the side of the breech.

I had one of those plastic breeches blow on firing (but this was with an upgraded Doug noble valve).     It was quite a surprise.  I replaced them with Doug's breeches which are made from higher quality delrin.

I loop a heavy rubber band around the trigger Gaurd and up over the bolt on my Badger just for this reason. Not cool having the bolt blow back upon firing because it wasn’t closed tightly.  Doesn’t take much to bump the bolt while hunting.

My wife's bolt-action SPA is what I would deem over-built.  There's a lot of metal, but when I compare it to my Shin Sung lever-action (both are .35/9mm), the lever action appears to be considerably more stout.

I'm inclined to say the lever-action big-bores win the "safest" category, but I haven't looked inside enough of them to know for sure.

And comparatively speaking, our stoutest big-bore are toys compare to the firing pressures in even small-bore centerfires.  Mind you, when I was at shore duty, I did engage in some destructive testing use HPA- and it will do some crazy stuff.  But those tests involved huge amounts of compressed air at 6k and more.  The tiny reservoirs we deal with in plenums in PCPs can ruin your day , but I think in regard to "safe" we're still talking way more safe than flying.

I feel perfectly safe with 3000 psi next to my cheek with my Texan.
