Before my answer, the true test of shooting Benchrest was on display in recent weeks. Just when the Pellet Benchrest world thinks the formula is science we have conditions that change the game. RMAC 2022 is the example that proofs the myth equipment vs Shooter. You can caliber and tune to perfection and then weather, draw for Relay and lane choice come to play and it all comes down to SHOOTER. RMAC has the most challenging wind, temperature deviations, terrain deviations and sun affect over the course of 4 hours and 3 days of relays. Then factor the psychology of shooting a benchrest target. Can the Shooter Rip a card in 90 seconds if the conditions are right. The answer is Marksmanship. Just because your gun shoots well at 100 yards does not mean it shoots well at 75 yards.
Caliber choice is simple BC. You see the .30 only because of WIND. The barrel and its effect on a Pellet is key in Pellet Benchrest. (Cut vs pressed barrel). So the Pellet shape and weight over distance is a factor. I shoot .25, a personal choice, I can read my shots better in .25. This is why wind killed me card 2. I experienced 10 to 14 inch wind drift in 45 mph wind.
The choice of gun and tuneability is up to you. I am the proud owner of all three and I can tell you all tune well. The FX Impact is most tunable at the bench over the course of a 30 minute match, that is why you see them in competition. The Crown is most accurate but needs an half hour to tune to new local conditions. The RAW I shoot .22 in 25 yard, 50 yard and 75 yard with a adjustable front rest and at these distances on true Moa targets is best to score.
So my answer is if you master TUNING, FX Impact is your gun. Show up and shoot, the RAW 2 clips, clean the barrel before each match and expect bullet proof reliability. If you like the ART, you know the conditions and can treat her like a Queen, the FX Crown 3 clips.
And remember If you can't see and score your target at 100 yards you did not spend enough on your Scope.
