RAW TM 1000 .177 cal my first sub inch 100 yd .177 group.
Posted: Sun Dec 30, 2012 9:46 pm
Just before Christmas at the farm I gave the .177 TM 1000 its first go at 100 yards.
This is the 6 th group shot and which came in a little lull in the breeze.
It measures ctc 0.794 inches 20.17 mm with "On Target".
I was quite excited to get a good one from the girly calibre.
It was shooting JSB 8.4 gr Exacts at 880 fps for just 14.4 fpe.
My slow motion videos are showing that particular pellet to stay stable with perfect flight from this rifle at velocity MVs from 675 fps/ 8.5 fpe to 900 fps / 15+ fpe - even in stiff wind. Some will spiral between 920 and 975 fps and virtually all are spiraling at 1000 fps. ...
Some other pellets begin spiraling at relatively low velocity. Any pellet that spirals gets blown further by a given wind. At 1000+ fps these good 8.4 gr Exacts can be blown twice as far off course as they are at a stable flight velocity of even as low as 700 fps.
A really pleasant finding for me is that this rifle will shoot the Predator Polymags to clover leaf groups at 25 metres. A Myna taken out today was an instant kill with a centre chest shot; just like with the .22 version.
Here's a shot on a dessert spoon swinger at 71 yards: 8.4 gr JSB. I think the spoon was already cracked.

And a couple of shots on a gum leaf at 87 yards lasered:

I think this is a very good rifle for a .177 and the 8.4 gr 4.50 mm head size pellets that I have seem to be a good match at this power. The Baracuda Match 10.65 gr 4.50 to 4.53 mm pellets are good at 15 to 17 fpe too. ... Hope this is of some interest.
Kind regards, Harry.

, there are some issues with them. The fill pressure seems to be the major issue as they don't seem to like working at lower pressures. I am sure this could be adjusted but........ 
Having to remove the cylinder to fill it seems to be a major oversight and there seem to be concerns about overall finish. One would have thought that since it has taken Diana such a long time to get into the PCP market that they would have done their R&D a bit better. That magazine problem isn't just limited to .177 either.
