Does anyone know the factory plenum size on XM1 Bullshark ? I can't seem to find it anywhere.

Oh, that’s amazing, I didn’t know about that. I usually practice and zero my Maverick at 3000ft altitude, because the farm my family owns is at the hills, and maybe that’s why I got good groups even @150m/165y using 30gr slugs. I was thinking about shooting 40gr slugs @1000fps, it would become almost a 22lr rimfire, but for that I’d need the heavy liner, right?Agree also. Of course, there’s a point at which physics catches up and if you’re close to that, you may not be getting the “advertised” BC. Also, if you’re shooting at higher altitude, you don’t need as much twist to stabilize because the air is less dense. Even at 4000ft, a 1:22 twist will approach the stability of a 1:18. Ultimately, if you can get away with less twist, the advantage is that less energy is wasted on spin.
Sorry for the confusion, I was trying to point out that lowering the scope height will not give closer hold overs at long shots. Even though I was replying to you, I was really directing my post to the OP. You already know all of this stuff.scotton,
In responding to the original poster, I was offering a potential solution/compromise that seems to help me. I'm using Air Arms 10.34 in a slow poly barrel in my USFT, that is producing a high BC in Hunter class at 19.5fpe. I'm using a zero of 30 yards. My holdover is very reasonable on both long and short shots.. overall my room for error is way less than if my scope was higher than the 2.25" it is now.
So, yes you are right under the conditions you are shooting within... heavier pellets, loopier trajectory, and clicking with a high power scope not set at 16x for Hunter class.
Even in Open or WFTF class, having 3 or 4 full turns to get from zero to a 10 yard target, in my mind is leaving a lot of room for error. When I shoot WFTF PCP class, I try to still keep my scope set at about 2.5 to 2.75" so I don't have more than one full turn when clicking from my zero to a 10 yard or 55 yard shot... but that's just what works best for me.
That 1.28" example you used is looking really good to me for a Hunter class shooter... especially a new one who might have a lot of things to learn about the game.. Keep it simple, seems like a good idea to me. I wouldn't mind fudging my zero and having a 1/16" hold under at 25-30 yards to make a longer flat spot in the trajectory.. again especially for someone learning the game. Most kill zones at 25 to 30 are 3/4" to 1", so being 1/16" high is not much of an issue to me... but even without doing that, it's a really safe trajectory as far as room for error goes.
How many points do your think are lost to competitors who click and make errors clicking from zero down to 10 yards... I know I made that mistake a lot when my WFTF class scope was 3.5"CtC above my barrel, in my early days of FT.
Ya, I got one i found had it's shortcomings like that.. lesson learned for the next one replacing it ..lol. also if it don't fit it's probably the wrong guage . Like a 4n Guage blade will fit inside a 4m hole..ect kinda thing..I have one imperial size thread gauges but it too big in size to get it into a 1/4" hole
It's for outside threads only
I'll have to get one of these "Nut and Bolt Thread Checker" gauges sets
