RAW's Cameron Kerndt Takes Gold in Long-Range at Oregon Competition

[Motorhead]

I just know Camerons rifle is not that high and recall his at @ 150-160 bar

Not my fight but let us not forget about gravity and time of flight to the target.
Shooting at 600 yards what is the time of flight?
Gravity is a constant so you better be seated on a nice hill or the pellet will strike the ground way short of 600 yards.
If you shoot a pellet from a horizontal rifle and simultaneously drop a pellet from your hand at the same time, both pellets will hit the ground at the same time.
Ballistic tables will confirm my theories!

 

[The Archer]

Frank,
Per your request… Time Of Flight = 2.1 sec. Silhouette was slightly over 200’ of vertical elevation and 1800’ from shots origin, impact at 4:30 o’clock, 3” out from center/600yd silhouette is 12”X20”. So shooting up hill and round did not land short of target in the dirt… per your statement.

Rifle: Modified AirForce Texan LSSCF .510
Projectile: Mr. HP (385 grain, 0.510 caliber)
Velocity: 956fps.
Shot: 1800 ft horizontally and 200 ft vertically, at 1500 ft elevation and 80°F.

The flight time math confirms 2.1 sec. You might find it helpful.
Vacuum model; T \approx 1.90 \, \text{s}, but v_f \approx 949 \, \text{ft/s}. With drag (C_d \approx 0.4), \text{ft/s}. Numerical approximation yields: T= 2.1 sec.

Pic attached is 400yd 8” gong (foreground) and 600yd is a 12”X20” silhouette (background). After a day of playing on the short range 100-350. I zeroed for 400 and took 10 shots with 9 impacts on the 8” gong. Last three rounds I had were sent at the 600, I dialed in +64mil of elevation and sent two, this gave me 12+ mil for wind and another 3.4 mil of elevation. Third shot making impact.

And… I have the video.

Frank, flight time of 2.1 sec. You might find this helpful. Destination was slightly over 200’ of vertical elevation above the point were shot wa taken.
Time to target: 2.1 seconds. Projectile (388 grain, 0.510 caliber) traveling 1800 ft horizontally and 200 ft vertically, at 1500 ft elevation and 80°F.

So… The vacuum model gives T \approx 1.90 \, \text{s}, but v_f \approx 949 \, \text{ft/s}. With drag (C_d \approx 0.4), \text{ft/s}. Numerical approximation yields: T= 2.1 sec.

And… I have the video to prove it. FYI; I never talk bull, because I don’t need to.

Honestly reads as if your trolling ... needing to validate your skill, ability etc might exceed an events result ?
So show those who are actually doing it that their skill & ability is sub par to yours .... It is Honestly how it reads

Long range… It’s a hobby for me, a hobby I take seriously and enjoy very much. Is kinda like golf, but for men. If that offends you somehow there is nothing I can say. As for trolling, you asked for the flight time, and you said the round would end up in the dirt in front of the target. Here is some advice, when you don’t know what you’re talking about, and positive feedback upsets you, maybe you should avoid posting uninformed opinions.

 

[Scotchmo]

Congratulations… I know how difficult it can be to hit targets at varying distances, but I’m a little confused and hope you can help. All shots are under 300 yards and they call this long distance? What am I missing?

For airguns, over 100yds is often considered ELR.

The Oregon match consisted of the following:

140yd, 2in square, 5 shots
166yd 3in square, 5 shots
187yd 4in square, 5 shots
250yd 5in square, 5 shots
300yd 7in square, 5 shots

Cameron had a 68% hit rate. There were no warm up or practice shots beforehand.

I appreciate the info. I've never competed in a sanctioned event and don't know the rules, distances, shot count, spotter, etc. No sighters clearly adds to any challenge, we all know it's easier to guarantee impacts if you can take a few practice shots beforehand. I keep my rifle zeroed for 100 and have dope for 25 yard increments beyond that, funny thing is... the first time I used my rifle for anything under 100 yards was on the hog hunt with Uncle Ted when I swapped out my scope for a Nightforce ATACR 1-8x24mm F1 and set the rifle to 50YD ZERO, and then created an entirely new dope chart for that one hunt. When the hunt was over I returned home and sold that little POS scope and moved back to LR, I meen ELR. lol

 

[Frank in Fairfield]

So, you are shooting UP.
Not horizontal.

It's also "long range" for a 22rf and if one doesn't have a lot number of match ammo that shoots well in ones gun, as well as low SD for 22rf ammo, it gets even harder because the vertical becomes poor at these distances with misses in the dirt, mostly low, but higher too. I've had mid quality ammo with 100 fps ES before, only a few per box of 50 but there nontheless.

I agree. I also reference long range in a different light. How far can I reasonably expect to hit a ground squirrel first or maybe second shot? No sighters, no warmup. You don’t get to walk in shots like that. For me, minute of squirrel is about 200 yards with my .25 Panthera. Have I connected longer? Yes, out to 286 yards. But that involves a lot of luck since that shot is 1/3 MOA. So I think 300 yards is a very long shot to maintain reasonable accuracy…

lol… ya I don’t shoot ground squirrels with a .510 cal. Not with any expectation of harvesting the meat! Also not a good idea to launch a 300+ gr. slug at a bird, too much damage to the meat and not enough mass in that bird to stop… or even slow the slug. Over penetration is a real concern here. Coyotes, hogs, dear, and elk are a little more appropriate for big bore PCP rifles.

 

[qball]

I’m not saying I can do better… just that 300 is NOT long distance with a modern PCP. At 400 things get interesting, and we frequently shoot out to 600yds. I’d love to attend one of these competitions, but it’s hard to get time off, so not practical. I was barely able to pull off the ranch hunt with Mr. Hollow Point and Ted Nugent. But you never know where I’ll show up next. lol

As other have mentioned long range really depends on the target size and condition. On a calmer day I can hit 12 oz soda cans with relative ease at 300 yards. I would like to get out to 600 yards, I suspect hitting a sofa can or even a 2 liter bottle gets a little tricky at 600 with any sort of wind.

 

[The Archer]

Not horizontal.

Well not exactly vertical, but shooting up hill indeed. We built two ranges locally and this particular spot has elevated targets from 600 out to 1,000yds.

 

[Frank in Fairfield]

Similar but different.
I used to belong to the Varmint Hunter’s Association. The monthly rag would print photos of shots on prairie dogs taken from allegedly extreme ranges. 600, 800, 1000, etc., and, in one exaggerated claim, 2700 yards on a windless day in southern Nevada…
While I would never call someone a liar on a public forum, I do consider myself a very serious rifleman even at the advanced age of soon to be 80. I have shot prairie dogs at 400-500 yards in Wyoming with my trusty .22-250. Never, and I mean never at those ranges was there a first shot hit. I have a theory about some of these long range hits on prairie rats:

Lou and Chuck are patrolling the prairie dog country and spot a likely town. They place an orange traffic cone in the middle of it and retreat to hillside 600-1000 yards away and start blasting at the cone. After a couple hundred rounds (none of which has hit the cone, btw) they drive back and see if any dogs accidentally stood in front of a speeding bullet. If they find one, a photo and story is produced!

Here on this forum a good friend of mine says he routinely splits playing cards at 200 yards with his air rifle. You and I both know he cannot even see a playing card on edge at 200 yards, regardless of the scope used. What he has is the playing seated on edge placed in front of a large black circle within which he places his crosshairs. Every now and then he strikes a card..

So, have your discussions but remember we take it all with a grain (maybe a few grains) of salt!
