Well I think U R all familiar with this rifle... I will tell U everything I know about it... Hatsan .22 barrel:Mine has Lothar Walther .22 barrel... I know that someo of you may doubt in this( and I have doubt in that and still not sure) because barrel looks same like regular bt65 barrel with 12 grooves and because of that I had email message to LW and they told they indeed selling barrels to hatsan... Then they forwarded my email with rifle serial number to hatsan and they confirmed by my serial number that I have LW barrel. I even have original emails from them if someone wants I can post them...My conclusion about barrel is following: material processing is 100% same as on regular barrel and they look 100% same except laser barrel sing "made by LW". So Hatsan probably have LW barrel blanks, and my barrel probably is LW barrel but that does not means that regular barrels are bad... Regular barrel is copy of Lothar Walther barrel so if Hatsan made their homework good U should not have any problems with regular barrel. Although plenty of hatsan owners in my country had big accuracy issues with regular .22 barrels( I am not lying here) and plenty of first series BT65 .22 were returned to stores because they had accuracy issues. Because of that BT65 .22 is not wanted rifle in my country. BT65 .25 is greatly accepted but BT65 in .22 caliber is not... People in my country prefer AT44...General thoughts:Weight:- For plenty PCP rifle enthusiast this rifle comes to heavy. But however it is not to heavy for me... But it is surely not rifle for kids... For example BT65 is heavy like HW 97 springer rifle...Synthetic Stock:- Very nice and adjustable stock in every way(cheek pad, but pad). Very few and much expensier PCP rifles have that kind of stock. Stock is very well balanced with picatinny rail... Some guys were not satisfied with this stock so they did this: Quattro trigger:- For me this trigger is pure perfection. U can adjust it to fit your needs by unscrewing trigger protector. All data how to adjust available on google. But however after some use gold plated trigger will became white So don't expect that gold will last.Accuracy in stock untouched version:- Well I can say if you don't have shooting chronograph U will not be too happy with accuracy. Why? Because of big pressure loss after each shot. So for example you will get 3 shots in 1100 FPS speed with JSB heavy, than next 3 shots in 1030 etc...But you can be very accurate with this rifle if U find its hotspot. Mine had best hotspot around 190-160bars and that was only 10 shots... I could shoot very accurate but only in this hotspot. It can do more than 30 shots from 200-100 bars but only 10 shots are fully regulated and most accurate... And I was tired of pumping so I decided to go on regulator;Altaros regulator and accuracy- This is best add on you can buy for this rifle. It is very easy and simple to install.. Follow this procedure:Unscrew, put air out of cylinder and put it into benchwise(put some rubber on bench vise) and then use either key 17 or french key for unscrewing air valve part. It will go very hard first time but after that you will not need bench vise. Then put regulator into air tube just slightly below threads, and then tighten air valve part without bench vise. Now take PCP pump and take around 200 pumping from 0-200 bars or U can do same without effort if you have Air bottle...Now regulator is in the air tube but it demands some fine tuning.If U R happy with 20 regulated and high power shots don't touch anything.If U want more shots than that U will have to do following:Unscrew all screws from synthetic stock. and put rifle out of the stock. In this stage U will have to adjust hammer spring inside rifle( very simple follow 3 stage procedure on picture belov). In order to adjust hammer spring you must unloose 3 tiny allen screws that are holding hammer spring...So now U can adjust hammer spring. Use appropriate allen wrench and start loosening to desired FPS speed. For start try to unscrew only 1 full circle, and than try the speed on chronograph.U should get about 30 regulated shots in about 1000 or more FPS with JSB heavy.If U R not happy with that shot count adjust hammer spring for desired level. Loosening means less FPS and greater shot count. So U can reach more than 50 regulated shots in 900 FPS range for example.Now U can pump it up to 215 bars without any problem. And this is recommended by Altaros personal.U can set it up from 100-150 bars. Mine is set up to 135 bars.This is my current shooting string(add 3 more shots in it because I had 3 "empty shots") with JSB Jumbo 15,9 grains shooting at average 976 FPS... More than 40 regulated shots from 215 - 135 bars.Magazine- I think magazine does not hold pellets well. Pellets are bouncing and protruding more and more after each shot and I don't like that. This rifle needs better magazine or single shot adapter...Reloading mechanism or side bolt- You can see it in pictures above. When you will receive new gun reloading process will go heavy like Mauser M98 and then after some time it will unloose and become much smoother than in new stock version. I like SB but I don't like magazine...mechanical sights- This is nice feature of this rifle if you don't have rifle scope. Truglo fiber optics. For fans of such shooting discipline. If you have rifle scope take front and rear mechanical sight out. What groups you can expect with this rifle?I use CTC measuring method and my average groups at 50 meters are 20 mm, while best groups on same distance are from 10-15 mm.I have video in which I am shooting first time over scope cam and groupings are not the best... I can do much better without scope cam... But they are good. Especially first group. U can check on tube by typing bt65.I am member of WFKS® (World Federation of Kalikakia Shooting) you can also check other great shooting videos from other WFKS® members on tube.Review will continue...
