Jsb jumbo heavy exact

[Deer hunter.]

Finally after seeing some posts purchased some sample pellets of jsb jumbo heavy exacts 18.13g pellets for my rifle and theyr the best so far by a long shot my rifle is zero'd at 25 yards and im achieving 12mm ctc which im over the moon with as im also shooting jsb pellets in my S400k in 177 (uk spec rifles)

My 22 Mrod shoots those JSBs well also, with a starting fill of about 2950 down to 1850. I can get nearly 60 shots prior to velocity tailing off to the point where POI is affected at 35-40 yards. They are not speed demons (about 765-785 fps thru the string), but are pretty darn accurate. I do have the occasional flyer, but that will impact within 1/2" of my int of aim at 35-40 yards. Mine also likes the good old Crosman 14.3's out to 30 yards. After that they group about an inch at 40 yards. Great for my pest control range.

I shoot them also and have given the beat results. Sub 1/2"groups at 30 yards.

Can't go wrong with the JSB's I have a modded Gen 1 and a Synthetic Gen 2 and both love the JSB'S.

Great accuracy in both!!!!

my crossman HP are running at about 925 and my JSB 18.3 are running around 855, Regulated at 1800 and conservative valve
I am also running the LW 630 barrel and accuracy is very good

I thought my JSB 18.13 were top dog in my .22 synrod until I tried the H&N 21.14 5.53 heads. Now they are top dog. I'm getting 3/8" groups at 50 yards flat out with an average of 835 fps with those H&Ns. Only 1/2" inch groups at 50 yards with the JSBs at 870 fps average.

Seems they either like the H&N 21gr or the JSB 18.13 gr. I tried both and the JSB's won.
