I'm a bad excuse for an M10 owner. Haven't played with it in quite awhile.
After due consideration of how the rilfe wiull get used, removed the 3-12X and put on a simple 3-9X scope. Just not going to be used any farther than a 3-9X can provide.
Guess I'm either complacent or the rifle fills a "slot" in the line up that's not better filled by some other PCP. Don't really "know" yet if it is a "must-have-keeper" or just one I play with now and again....time, use will decide that over time.
Cured the trigger. Then cured making the (stupidly placed) safety work with the trigger adjusted. Ordered really heavy weight pellets to better deal with the power output. Tried various transfer ports to decrease power and extend shot count
Results were great, but I just don't have anything that needs shooting at that power level or all that far away until huntring season rolls around again.
Disgtracting me: I got into the really quiet rifles, and put the M-10 to the side for a time (it's still holding a steady pressure, so it's likely "healthy"). More need right now, with only pest birds on the "legal" shooting menue, and shrouded/LDC's low power is better suited for the season here (warm...neighbors out more...no game animals to shoot).
Had a couple of tests at various speed with my nephew...he's happier with the Discovery, as that cost about as much as this did on sale, figured "what the hay" and let the Disco. go and kept thr M10.
Settled on a 3/4 throttle setting of a bit less than 42 foot pounds. It has 53-51 foot pounds with no sweat, but 40-42 seemed to be "enough"...fast enough that real heavy weight pellets aren't really trajectory challenged (still in the 800's) but still able to toss 18.1's at a reasonably slow/accurate speed (more like 980fps).
Reasonably efficient. Not 100% sure what the real air volume of that air tube really is. Have seen 255 cc mentioned, and if it really is that size, then the efficiency is about 1.3. I'm thinking it may be closer to 270cc's, which would make the efficiency more like 1.24.
Neither of those is earthshattering....but I'd not take it apart and rework the system for the difference.
Did extend the LDC rather than make a new one. Just a suspistion, but SUPECT the isse one has so many close-set baffles that the air speed (and sound) reduction is hampered by lack of volume when cranked up to full power. The extention makes it at least "usefully" quiet when tuned down to the 38-42 foot pound level.
Soooo...I'd kind of inactive and silent about the M10 for now.
I really do NOT want to transform it into something that isn't in it's basic nature (that being a really fast/high powered unregulated PCP) as that exact nature would be a very good thing come next hunting season. Found over the years, that pcp's forced/tuned into power leverl they aren't natural to tend to find ways of letting you know they aren't happy (blowing seals, needing readjustment, not keeping thier zero, etc.).
Let 'em live in the "zone" they seem to find to naturally wanting to shoot...fast or slow....if you really need a faster/more powerful one, buy a new one (and if you need a quieter/lower powered one, buy one of those as well).
Tell ya'll what...let me "whack" a couple of bothersome garbage can raiding racoons, and I'll re-evaluate the rifle's uses for me at this power level. It kind of likes the odd-ball 19gr. H&N "X" shaped head hollow point, the speed would be enough to get it to expand on racoon sized critters, and I'll report on the results.
As for too much more drastic experimention...why?
As for the new repeater version...I'd have to see three things:
1. Is here a really decent single shot tray that with it?
2.Price...there seems to be more compition at the lower end of the PCP scale than there is anywhere else right now.
3. Is the new version more in tune with "moderate" power, or is it more like the original M-10's "male-round accessory package-to the-wall" type of tuning?
