Best Pellet for my BSA R10 SE .25 cal

The best place to start in any accuracy quest with any caliber airgun is JSB pellets. More specifically, light-for caliber JSBs in modest-power guns, medium weight JSBs in mid-power guns, and heavy to super-heavy JSBs in powerful to extreme-power guns.

This is not conjecture. Rather, decades of experience testing hundreds of airguns.

its a beautiful gun no doubt.. I'm still getting the right pellet figured out. I also rebuilt a compressor for it so I didn't loose the bank getting one.. The Benjamin pellets I tried this last weekend where horrible.. Really a crappy performance. the only good thing I could say was they were cheap.. The compressor is the ReadyAir. works great.. I'm wondering if the clips I have might have a problem shaving the pellets.. and that might impact my accuracy. Ill take them apart and see if there are sharp edges and if they line up right while indexing. it would be kool to get a couple more shots in also.
 
"Also whats the advantages of the Huma Regulator?"

Simply stated, like JSB pellets, Huma is the best. By the way, FX, Air Arms, and Daystate Rangemaster pellets are JSBs. To quote The Voice Of Experience, "The best place to start in any accuracy quest with any caliber airgun is JSB pellets."

A buddy has a .22 BSA R10, and I found it one of the most accurate airguns at 50 yards I've shot... with 18.1 grain JSBs. Here are my testing notes-

18.1gr JSB Exact, 3400 PSI, 43 shot powerband- Low= 827, High= 850, ES= 23, SD= 6, Average= 835 FPS/28.0 FP.
This rifle was tested brand-new (no adjustments or tuning). It was incredibly accurate!

 
I am curious as to how you like this rifle? I just picked up a bsa ultra jsr and am impressed by the little guy. Now I'm thinking I need an R10 lol.
Its a beautiful gun... .. I wish it was about 2 ounds lighter but its around its counter parts weight.. Its just amazing that its heavier than my Poweder burners.. lol

All my airguns seem to be bulkier and heavier than my powder guns. Wish they could make a high power high shot count small and light air gun but that's kind of next to impossible I guess.
 
It's hard to add a large air reservoir without adding bulk. And the larger the caliber and/or higher the power, the larger the air reservoir needed. The second challenge is making an air reservoir that is affordable. A titanium, or maybe carbon reservoir capable of a life at 3600-4500psi (again, higher pressure to improve shot count) ain't cheap, but it's something you most definitely don't want to cut corners on.
If light and svelte is one of your primary needs you could look at a .177 rifle with a tube reservoir like a Daystate Huntsman. There may be others that are even svelter and lighter. I know motorhead can tune a Marauder to push 100 shots per fill in .177 @ 18-20fpe...but some would still call a Marauder bulky, and it's definitely a little on the chunky side.
Personally, I think a Daystate Huntsman with their electronic valve like they put in the Wolf guns would be highly desirable, but I haven't seen one mentioned yet.
