HDR 68 Revolver and First Strikes

[Knight4612]

Does anyone know what FPS the HDR 68 Revolver is averaging with First Strikes?

230-250 on a fresh 12g without mods

Mine is getting around 275-280ish on a fresh one. But it drops fairly early in the 12g

YMMV! capitalpaintball was shooting his yesterday and we saw up to 294.

Ok, so they don't have such variation out the box 😅

Which way did you drill and how much?

[capitalpaintball]

I should of paid more attention to what size drill bits. I removed the restrictor and got 388 fps with a reball, so i drilled it out on both sides and put it back. numbers are better, but the force of the bolt hitting the balls breaks 90% of the paint. FS are better but i still had a break but it was on a pre-used round so it may have been stressed from previous shots. its still a work in progress

No problem, I was just curious.

I drilled the restrictor through but didn't enlarged the transfer port. I also shortened the firing pin. I may make a quick guide if people want to give it a go.

If it’s shooting 230-250 with FSR, I’m assuming round ball is -20 FPS. Is that correct?

Mine was shooting 280 out of the box

Same for mine

Here is stock without mods, but some people seam to get higher velocity ...

Popped a fresh 12g in and here are the results:
- first shot with FSR: 230 to 250 fps
- first shot with round ball: 200 to 230 fps
The velocity remains pretty consistent until shot ~15 then start to really drop around ~20 or so ...

Got a few breaks, seam to be happening when the ball is small enough to slide forward into the cylinder ... Need to investigate further.
