Snowpeak PP700 transfer port

[Loki_762]

I recently bought a PP700 SA that originated in Canada. From what I understand, to get my gun up over 500 fps in .22, I’m going to need to drill out the transfer port. Is there any tutorials on how to find it, how to get to it, and how big to drill it out to?
Thanks,
Chris

Jefferson state air rifles sells / used to sell replacement breech blocks for a reasonable price with different size transfer ports, all of them larger than the stock transfer ports. You can buy one in 22 or .177. They are well-made and even have a little groove designed into them to assist with pellet loading, an improvement over the original design.

The transfer port is in the part that you swing open to load the pellet.. it's the hole that lines up with the barrel... I don't know what yours looks like but mine has a hole in the top of that block with a screw in it that you screw in or out, blocking or unlocking the (transfer port) hole to regulate how much air is allowed to pass through it..
