Maybe i can offer some insight as 100 meter benchrest is quite popular where i live . Also please excuse my crappy english .
The FX boss is known to perform well at that range. Match results always have some FX bosses in there.
The RAW .30 is also performing good @ 100 meters. It's still kind of "new" , at least here, but they are slowly getting more popular. I think about the same accuracy as the boss can be expected, but i've never shot one personally . But definately worth googling. The groups i saw are promising.
The bobcat .30, not so much strangely. Nobody shoots it competitively . (more on that in a bit as i've owned one briefly myself)
The bobcat .25 (you wanted .30 though)
Daystate Wolverine .30
I've personally owned the Boss, (still do), the bobcat .25 (still do) and the bobcat .30
Each have their advantages and disadvantages in my noob experience.
The boss , i find, needs to be held a little firmly. You (or i maybe :d) can't just lay it on the sack while barely touching it and shoot. The rifle moves too much for that during the shot . I personally use the fill plug against the shooting sack the same way as you would "load" a bipod. (of course this only works if you shoot tethered).
Because the boss is fairly light, and the stock is kind of narrow, it is in my experience pretty hold sensitive. I also often shoot 2 groups if you know what i mean. Shifting POI is common, at least when i am shooting it
. Maybe i'm just a crap shot who knows. That's my experiecne though. Out of the 3 100 meter guns i owned, it is potentially the most accurate though. But i personally don't find it that easy to shoot.
The bobcat .30, MUCH more stable on the shooting sack. Because heavier, wider, and bulkier. When i put it on the sack my initial thought was "ok this is going to be easy", that's how stable it was . However, for the whole day, i could not get a single decent 5 group shot out of it. Granted, it was the first time i shot it, it was brand new and i hadn't cleaned the barrel . So maybe the barrel was dirty, or maybe the stars weren't alligned, but i had a lot of shots that felt perfect, untill i saw where the pellet hit and i really couldn't fathom how the hell that just happened.
Others reportedly can shoot good groups with the bobcat .30 @ 100 meters, however, you never see it used in matches so maybe the slight pellet speed reduction does have an impact on accuracy compared to the FX boss. I personally think the Boss is more accurate, altough trickier to shoot .
The bobcat .25. Very easy to shoot, barely moves when you fire a shot so you don't have to grip the stock . Groups are a little wider than the FX boss though, and there's the odd flyer here and there. I guess that just comes with the smaller calibre. Also have only shot it for one day so maybe i just still suck with it.
A lot also has to do with the JSB pellets. So everything i have said maybe nonsense in the end
Especially the .30's lately have been ALL OVER THE G^DDAMNED place. No two tins are the same. I don't know what they are doing down there but it isn't good.
I have no personal experience with either the RAW or the Daystate.
p.s: Indoor shooting only , front rest only . Can't tell you anything about shooting outside. But i'm guessing the .25 would take a severe beating vs the .30 if a little wind gets involved.
