Howdy Steve. I'm shooting the 24.5g JSB's Kings @ 860-875fps. They seem to have about the same drop and wind drift as my 30fpe .22's (with 18g jsb's) -but the .25's just have a little more smack on target. Its nice to hear that steel RING! haha... For a power bump on your Royale, you could try Allen Z -but I've had my guns disappear for LONG periods of time when I send stuff to him. You've got AoA right there, I'd ask them about it. A longer barrel may be a good way to go (you may want to ask csdilligaf about his benchmark made air gun barrels). If its a non-regulated gun, you just need to tighten up the hammer spring a bit and see what you can get. How much higher would you like to go? If you've already got a .22 shooting the 18g JSB's somewhere around 875-900fps, I don't think you'd gain too much by cranking up the power. Are you hoping to get into a heavier pellet?
If you want a good 6 fpe olympic style rifle, there are some great deals to be had on used FWB 300's and RWS 75's that pop up on the classifieds once in a while. The FWB is a springer but they are awesome and can be picked up used for $400 to $500 in great shape. Woogie_man has a nice pic of one higher up this page. I grabbed a RWS 75 for $375 and it has been awesome -such a smooth shooter, its just like shooting a PCP. Its got an amazing 3 oz trigger. VERY challenging to shoot in the wind. If you want to spend a little more, the FWB 603's are awesome, but its a little tricky to get a scope mounted on those. After that you're looking at a PCP and spending over a grand. The AA MPR's look nice and come up used once in a while for $600-$800 and I think you can adjust them from ~6-12 fpe. AoA has a nice looking used FWB P500 that's been sitting on their shelf for quite a while now. There's a pic of it on their used page right now. I bet you could talk them down a bit on that since they know you, and they've been sitting on that gun for so long now...
We have a couple of fun 200 to 600yd "steel dog" matches here in the Denver area. We shoot prone w/ bi-pods at steel p-dog silhouettes and other steel popper type targets. At 500+yds those steel P-dogs are NOT easy to hit in the wind we get around here. I guess the most exotic match I've been to is the SRM in Raton so far (LOVE it down there!). I'm all for branching out and trying some true "tactical" matches. But no experience with that stuff so far. I'm hoping to get in on some of the action up in Douglas, WY one of these days. It would have been great to swing down to Flagstaff for FT AND a long range match but too bad it sounds like its not gonna work out...
Are you going to a FT match or BR at LD's? His FT matches have some targets well past 55yds, right? Sounds like a ton of fun. I was working in San Diego once and got to shoot a BR match with LD and his crew. Very good time. LD is a lefty and even let me borrow one of his USFT's for the match (he also let me shoot his lefty whiscombe!!!). I remember I came in 3rd right behind LD and Tim McMurray that day. He's got a great shooting spot out there. I'd LOVE to test a few of my guns in his 50yd tunnel! Have a good time out there. I wish I could join you!
