Keesbo,
Thanks for the link, i will read it with great interest, i hope you will keep an eye here and help guide me, the bolt security worries me a little and i know i cant achieve the same solution as you did.
Are you still enjoying the gun, has your grouping stayed good at 50 mtrs?

Yep, still enjoy the rifle. Accuracy is good enough at 50 meters. Use the M25 about 2 times 50 shots a month.

I only used a drillpress and a Dremel machine.
Just good old handwork.

Keesbo,
I have just translated your post and read it all, thank you for showing your work.
When i first saw your post without translating it i assumed in the photos it was a milling machine, not a simple drill press

It looks like you really improved the grouping and more so the FPS seems very stable between shots. Can i ask how did you polished the barrel at the leade end?

I removed my bipod also and now shooting from a sand bag and have also found it to shoot much more accurately but i am using 4 pieces of the silencer without any current issues but i will surely try it without.

Alex you are correct in similar power levels between the two. However I have learned in the last five years actually the last three how devastating an energy dump is on game. My experience is with smaller game but I imagine it would be the same on medium to larger game as well caliber appropriate. I was impressed with how quiet mine is with only three baffles. Glad your enjoying it.

I think that I used a big Brass screwhead  and polish paste.
Barrel in the lathe and the screw in a cordless drill.

Hi, i meant how did you polish it to such a shine where the pellet enters the barrel.
I could see you had removed burs but it also looked very shiny and highly polished, great looking work!
Thanks

Ah, used sandpaper, 240-400-600-1000 grid.
And set the barrel in the lathe offcourse at 300 Rpm

Just the articles i read stated about a 40 grain slug/bullet in the 22LR giving the 120/160 FPE.... that would be half our grain weight and has me a little confused

Speed makes the difference. 22LR is way faster.

My heavily tuned .25 M25 makes 144fpe with 45gr slug.
