I have the Sniper HR in .22 and have been very satisfied. For context, I am new to PCP's but not to airguns owning several springers and pumps since the early 80's. My only other PCP is Gamo Urban. I have added a Sightron S2 Big Sky 4-16 mil dot scope with medium Burris Signature rings, a DonnyFL moderator, and Noveske flush QD mount for 3-point sling. I have put around 2K pellets through the Sniper and use it exclusively for squirrel hunting. I purchased the sniper because it checked all the boxes for me - quality barrel, free-floating barrel, threaded barrel, semi-bullpup (short overall length), regulated, large air capacity, regulator/spring tune-ability, ability for low scope mount, adjustable trigger, quality magazine, relatively low report, and overall good looking IMO. After owning and using for several months, all the above hold true for me. In fact, the trigger is better than I expected and was adjusted very easily to under 2lbs with zero creep and excellent predictability. The gun was even quieter than I expected and with the DonnyFL, it sounds like a toy. You quickly realize the power when the thud of a pellet impacting squirrel echos through the woods! i have not spent a great deal of quality range time and most of the ~2K pellets were fired indoors at close range. I have shot it through the chronograph on multiple occasions and found the JSB 16's running at around 880 and the 18's around 850 with my reg factory set at 130. The 16's appear to shoot the best but, again, I really need more bench time in perfect conditions to sort out which pellets fly the best. Currently, the 16's make a ragged nickle-sized hole at 35-40 yards (range I shoot most squirrels). While the Urban does this as well, I only get about 25-30 shots before requiring a refill. I truly lose count with the sniper but it must be dozens of shots before the impact falls below that nickle-sized hole, requiring a refill. I have not altered the reg or hammer spring tension but may after squirrel season ends to accommodate 25gr JSB's. Fact is, I could leave the settings as is and be content.
So, am I disappointed in anything? No. However, I do wish the pistol grip were slightly larger. I have big hands so many folks will not find this an issue. There are a few, say a dozen or so, tiny lead shavings on the magazine shelf after I fire a tank of air. However, the mag feeds well and I have had no issues with jams. I cannot comment on long range accuracy with the mag vs single feed as I have not tested anything yet. However, the minute of squirrel head is spot on out to 40 yards and probably much further. I agree with a previous post that the bolt needs to be locked down when closed. If you are not careful, you can unknowingly bump it open while hunting and fire with the breach open. The gun is heavy compared to the Gamo, but, it's not a big deal to me. I am used to carrying far heavier varmint-barreled rimfires in the woods. I have to say that I like this little rifle so much that I have not taken a rimfire into the woods since owning it, and that's saying a lot as it has seemingly replaced a highly customized and extremely accurate Sako Quad as my go-to squirrel gun.
