I'll never be able to measure or quantify this, but I do notice small POI shifts with temperature variations of 10deg or more. And for sure this is more pronounced with more powerful guns. That is probably why my hw30s varies the least. That is why I always check zero if I'm going to be doing...
I am often surprised at how accurately I can shoot my springers, given as you say, their sensitivity to even the smallest change or tweak. Even a quarter turn on my stock or trigger guard screws can alter my POI a bit. R
Scopes only for me. Just can't get comfortable with peeps or open sights, and I like the extra accuracy that comes with a scope. That said, I hate heavy/bulky scopes. On most guns, I've found the best setup to be a Hawke Vantage 2-7x32ao. R
Glad you have your hw95 shooting well! l've had to go through a similar routine with all of my new Weihrauchs. Remove OEM spring, seal and lubes. Replace with an ARH spring kit, Vortek seal and properly re-lube. And I've always gotten better accuracy by tuning down the power. R
My read of the evidence is that high quality spring guns are a dying market, and therefore new R&D or investment just does not pencil out for manufacturers. The few attempts to bring innovative and/or high quality new products to market in the past 5-10 years have all failed. The new FWB pro...
Congrats and you are off to a great start. The hw95 should give you a lifetime of fun, accurate shooting. It is easy to go down the tuning rabbit hole, especially if you read this forum, but that certainly is not necessary to enjoy shooting and hunting. R
Even if you focus on buying used, it will be difficult to find a quality (accurate) spring gun in the $300-350 price range. HW50s or hw95 are great options if you can find one in your price range. Hatsan spring guns have mixed reviews for quality and accuracy. A Umarex notos PCP, with a...
I have an ARH plinkers kit in one of my .177 50s. It shoots JSB 8.4s at 700fps, a bit over 9fpe. Excellent setup. I have that kit on my bench waiting to go into my other 50s. R
Good to hear you have your hw50s shooting well. My hw50s in .177 is my favorite spring gun. Just right in terms of size and weight, relative to power. I always get optimal accuracy when I tune to somewhere between 10fpe and 11fpe. R
ARH moly or ultimox 226 have both served me well for many years. There is more work involved to use ultimox 226 because you have to thoroughly clean out old lubes, but I find that it has (slightly) less sensitivity to temperature. R
Bought an R1k from them 10-12 years ago. They provided a lot of useful empirical data on FPS/FPE for springers with various pellets, and very helpful gun reviews in the 'our take' section of their website. R
