The 2016 Extreme Benchrest results show which rifles were used by the participants but not the caliber. What caliber(s) are they using?
Calibers used at Extreme Benchrest
- Thread starter beeser
- Start date
Ted (who wons the extreme 100) used an impact in .25 following his lastest video.
I suppose 90% of others used .30

I remember back when the 177 was the flat shooter, Then the 22 became the new 177, Now with all the power the 25 becomes the flatter shooter, Or is the 30 cal the new 177 ? I think with the upsurge of the PCP guns they have come further in the last 10 years than they have in the last 30 years,
I could be wrong by a year or two,

.177 still the flat shooter, but the heavier calibre the most stable, especially for outdoor shooting.

It depends on the distances involved and the power of the airguns. .177 only has a flatter trajectory than a 22 if both guns have equal power.
If you tune a 177 and a 22 to shoot at the same speed then the trajectory would be about the same until you got to a certain distance. The heavier projectile would then carry further.
Due to the nature of diabolo pellets, we tend to limit their speed to below the speed of sound and modern PCP rifles are typically capable of sending pellets as fast as we would want them to be in 177, 22 and 25 caliber.
The whole "177 is flatter" thing applies more to typical FT and BR matches where power is limited to 20fpe (or 12fpe) regardless of pellet speed. In that scenario, 177 has a flatter trajectory but in the real world, or at Extreme Bennchrest, it is irrelevant as you would increase the power of the 22 or 25 to compensate and give you the trajectory you prefer.
177 pellets also have the advantage in scenarios where group sizes are measured CTC without any adjustment for caliber. It is clearly easier to achieve smaller groups with smaller holes. A clover leaf with a .177 is far less than 1/2" CTC but a clover leaf with a 50 cal is an inch and a half CTC.
Heavier pellets do better against the wind of course, assuming that the pellets are traveling at equal speed. If the 177 is traveling noticeably faster then a heavier projectile might lose some of it's wind advantage.
If I was going to compete with 100 yard targets (or more), I would probably want a 25 or 30 cal. If I was to compete in a regular FT match, I would probably choose a 177.

i shot a 25 last year in the 75 yd and a 30 this year in 75 & 100, a friend came in 7th with boss 30.

Actually groups are measured edge to edge at their widest point then subtract the actual diameter of the projectile giving you the CTC group size. Score matches benefit from the larger calibers because they are generally scored best edge meaning your bullet hole could be 99.9% in the 9 ring but if it cuts the 10 ring its scored a 10.

Is there an actual video of the 100 yards EB match? I watched the overall EB video, but would be great to watch Ted's shooting.
