It is set at 12 fpe right now. I am giving it a bit of time to settle in before
locking it in at 785 fps with the 4.51/3 JSB.

Two Steyr's, one for each Division. Excellent decision.

It makes a lot of sense to use the same platform. I have been giving that a lot of thought lately.

Like some have said... "beware of the one gun man". He gets to know that one gun pretty well. In this case still two, but so similar they feel essentially the same.

Someone will explain it here I'm sure, but it has something to do with international rules....
FT is a great way to enjoy the air gun hobby and learning the sport is just like any other sport, it takes some getting used to before it all makes sense..... Wink

Thank goodness for the dedicated air gun sport enthusiasts for bringing it all together and showing us newbies the way..... Cool

In short, the British FT Assoc. had set their limit based on the rifles they could use anywhere without licence. A vast majority of their clubs are for rifles less than 12 fpe, so that was what they set as their maximum power level. With my particular rifle and pellet, 800 fps is right at the top of that limit and you find, with poking around on their forums, that 785 is about the limit that they will set their rifles to. Some go so far as to set it even lower, in the 760's, but they are the exception. When I am finished, I hope to have two nearly identical rifles, set for a single pellet each. There will be no distance markings on the scope wheels, only what clicks I need to set them too. The S&B worked flawlessly that way and I am sure my trusty Deben will do the same. All I need to do is to print up a new tape for the side wheel and one for the turret. Yo Ho.

So I need to find the weight of my pellets and put them through the chrony and keep it close to 12fpe...........gotcha

Just remember that the 12 fpe level is only needed for rifles used at International Championships, in countries where the limit is mandated, and in competitions where "International" is offered as a sub-Division. Other than that, in North America, the normal power level allowed by the MD's is 20 fpe, regardless of Division. There are at least three countries where a vast majority of the countries' shooters, use 7.5j rifles, as those above that level are firearms and licences are very hard to come by.

I finally sat down and did one of the most boring aspects of shooting a mid-powered PCP there is. Total shot count for a fill. This was dreaded, but it had to be done so that later, when I get into one of those spots where the number of shots that has been fired (remember, exact count, not approximate in this case) has been lost, I know that if I have shot a match, plus up to 50 sighters (very, very rare for me to fire more than 30), I now know that I will have enough air to shoot another entire match left in the tank. This is more important when an immediate shoot-off happens and it is seldom that you shoot more than 60 competition shots in one day, but it can happen. The US Nationals, last year, was the perfect case for that. We shot 120 pellets in the first day.

I started with a full charge and 178 shots later, it finally dropped off the regulator, but still held on for another 15 usuable shots before dropping off too much. I was originally going for 795 fps, average, but after shooting a few hundred pellets out of it, the regulator and striker spring settled into 797 average, with the JSB 4.52's. When I switched to the 4.53's, the velocity climbed a bit more than I wanted, and ended up at 801 fps, average. That doesn't sound like much, but it can be enough to put the rifle over 12 fpe, which is the goal of this rifle. After refilling and doing another 25 shot check, it was the striker spring settling in and a small adjustment back and I have it now at 787 average. There is virtually no difference in POI from the 795 down to 787, but at least the rifle has a bit of wiggle room.

When I had started this conversion, I would have been really pleased with 125 shots from a full charge, but to exceed it by nearly 50% is really cool. I should have figured more than the 125 mark, as it gets more than 400 shots when it is set at 10 meter velocities
