Last night I pumped up the Tank. Rifle appeared to have about 50 BAR in it. Pumped it to 100 BAR. Cleaned the bore with Crown saver and pellgun oil. Made a couple of passes cleaned out manufactoring crud and ran a couple of dry patches. Also cleaned the crud off the outaside. This morning I finished pumping up the tank to 200 BAR per manual specks. Nice to note that rifle uses same fitting as Maurader and Disco. I will be glad when I get the adapters to fit my SCBA tank. Took Chrony outside and set up range. First shot out of barrel was 580 fps!! CPHP 14.9. This was dissappointment, but hoped it would get better. By end of first 10 shots got a high of 697 fps and low of 580 for an averqage of 630 fps. Difference of 117 deviation of 38%. I know these numbers are low but not bad for first ten shots. Now I sighted in thee scope. This scope is my everything scope. It is a bug buster mini and very nice scope, however, it is to short for me. I just can't get it far back enough so it goes on every gun I get untill I decide what scope I will use on that gun. I went to about 10 foot from target and sighted in the scope. Then went back to my 60' distance and fine tuned the scope. The rifle seems to be very accurate as I am not reallyt trying and shot are grouping very nicely. I have pulled a few and possibly a few flyers. I must have consumed about 40 rounds so I put the chrony back up. this time the High was 768 and low was 682 ave was 724 wuth a difference of 86 fps. that was a 27% deviatgion. Still using Crosman CPHP 14.3 bought from Wally World. Put the pump b ack on and looks like it ha about 50 BAR left in tank. Not bad being first time out.
So Far Likes
1. Fit and Finish Very nice Not sure what type of wood either beech or possable bambo
2. Weight with scope is just about right I will weigh it but guess about 8 lbs.
3. Trigger is just about right for me. Can't really feel the 2nd stage but I had been shnooting it without really thinking about pulling the trigger. It just seemed to be there.
4. Like the way it was packed. It was in a solid block of styrafoam instead of peices, and then covered with full sheet of cardboard. Then that was put in a box. Did not have to double box it. It was shipped via Brown Gorillas and arrived in very good shape.
Dislikes
1. The only dislike I have so far is there is no air pressure guage on it. The Crosman Pump has a guage on it but you have to pump the pump to get the guage to show pressure. Sort of a guess as to how much air is the tank.
Upon thinking about it I guess the first several shots were slow because it was getting rid of the Chinese air that was shipped in it. lol
I will shoot again tomorrow if it stops raining. I will apologise for the roughness of this writing but I managed to make it through life without having to write much. I usually gav e my information to somebody else and they took care of the rest.

what i found with mine. from factory gun does not like 200bar. hammer spring is too weak. i fill to 150-160 bar and i shoot cp14.3 at 970 fps. you have to change out the hammer spring if you want to fill that high. the low pressure fill doesnt bother me as its easier to hand pump in the field if i need to. i've been using it for squirrel and for the less than ten shot i may get, it works fine for me. i believe you can get a stronger spring from "big ed". mine is deadly, and i mean DEADLY accurate out past sixty yards. so much so that i don't bother shooting target with it as it's not even a challenge! mine shot the same 580 the first time i filled it to 200 but got faster and faster with each shot. try a lower pressure

Nice report. What grizzlyadams said....some guns like to be filled only 3/4 way. Change the hammer to a heavier hammer or change the hammer spring, and there will be a difference....from what I've read. I was lucky....all my PCPs arrived perfect....no need to change parts.

Great news on the B50. Well sort of. Now I guess I will have to buy this one too. LOL!!
Thanks a Lot
