Savage 110 & Viper PST Ranging Practice at 953 Yards
HTML-код
- Опубликовано: 10 сен 2024
- Here I am practicing my mil-dot ranging at (what turnd out to be) 953 yards. This is my first time shooting at this great a distance, and I DO NOT actually hit the target. It's a 12" steel action target Evil Roy set on the side of the mountain across the valley from another mountain top where I am located. I was very close to hitting this thing a few times, but I need a bigger target for that distance. I'd have to be a super-sniper like Tibor to hit this thing!

Also get a cheap laser thermometer at harbor freight and log your ammo temps prior to shot. Watch for the ammo heating up in the chamber, minor temp changes can cause big point of impact shifts at that range. Keep bolt open until you're ready to fire once you have sent some down range. Increased velocity due to heating ammo also increase spin drift.
I really like your videos !
thanks for sharing !
What's up Izzy! That's a long way for .308. You gotta be very accurate with your MVV and wind reads to hit that MOA target. I'm in the process of recording muzzle velocity variation at all temperatures possible 0F-100F. I noticed the powder I am using (Retumbo) is not very temperature sensitive so the mvv curve chart didnt work off of my one mv recorded at 100F. The curve chart left me 80fps too slow at 60F. I learned almost everything I know from Rex's videos. I am going to the desert on early Thursday morning with my ammo in a cooler and I am going to take a shot though the chrony at every 10F ammo temp rise. Measured with my infrared temp gun. Shots gotta be quick because of chamber temps but Ill try to let it cool between shots. It should help to make decent tables. I just helped my good buddy hit 1000 yards for the first time last week with his self bedded $400 Savage 30-06 with a $300 6x42 Swfa Super Sniper. Kevin
What's up 11! Thanks for the comments. Sounds like you're probably way more dedicated to the task than I am! I definitely need to rewatch all of T-Rex's long range videos. Excellent stuff. I also haven't been able to get out as much as I'd like. Need to get out there and practice more! Thanks again. Izzy
Download the ballistic tables in the description of this video and get good data on your muzzle velocity. ruclips.net/video/KpSPqJV3RnY/видео.html
Also watch the spin drift and Coriolis correction video from T-Rex sniper101 RUclips series.
Hey Cloud. All excellent suggestions. I do need to review Rex's stuff. I'm about to go out and try this again this week. Thanks for the tips!
Hey Izzy ... are you shooting slightly up hill? If you are could affect POI! Also I agree with 11 that ammo temperature will have a marked effect on your shooting and POI.
For what it is worth! :)
Try to get a spotter out there with you.. Log every detail about every shot. Do you like the Acutriggers on the Savage?
Looking at this video makes me think of the explanation tutorial video about how ammo temperature has a significant effect in muzzle velocity due to certain powders change burn rates dramatically.
Having about 1 to 3 MOA worth of drop or rise due to muzzle velocity change is a big deal out at close to 1,000 yards and farther.
Wind was not a huge factor in the misses but it can't be ignored either.
I doubt the shooting angle had much of an effect here, as the steeper the angle the shorter the adjusted range would be. You would be hitting higher, not lower.
In short, if the gun was zeroed properly and all other data was correct. I think you were chasing the elevation gremlin caused by poor ballistic data on your bullet velocity.
Good shooting!
Izzy, you're getting into the transonic zone for 308 at that distance. Unless you're running Berger 185s or heavier and pushing the velocities that's something to be cognizant of.
*True your ballistic algorithms at around 880 yards (start of the transonic zone for 175 SMKs) by inputting different MVs until the theoretical drop is the same as reality.
*Practice reading the wind. A bad wind call will cause you to miss more than a high standard deviation.
*When you dial for wind, make a full adjustment. Don't adjust half way then favor/hold the crosshairs. Then you'll be "wishing in" bullets and they just won't cooperate.
*Load your bipods with a slight forward pressure. Get behind your rifle then lift your chest slightly and move forward an inch or two to provide forward pressure.
*Whenever you break your cheekweld you run the risk of having a slight POI shift, especially if your parallax isn't adjusted properly (crosshair and target in same focal plane). Make sure parallax is adjusted properly and load and fire three rounds without breaking position.
*Fire two or three shots as accurately as possible (good fundamentals) then make your windage/elevation adjustment...otherwise you'll be chasing the spotter. Two or three isn't a proper sample size (statistically) but it'll give you a general idea of where the bullet will impact, then you'll adjust your high density hit probability onto the target.
*Practice relaxation techniques and your mental game. I use the key word "center" when I practice relaxation then I use that word when I'm on rifle. "Center" will induce a relaxed state when I'm shooting....Pavlov's dogs. Also do the positive mental attitude talk...I shoot best under pressure, in 112 degree heat, with rocks in my ribs, with heavy mirage, etc. Instead of saying I missed by .1 mils say I was within .1 mils of connecting. It's some Jedi Knight Ninja tricks that make all shots possible!
Hey Browneye. Excellent commentary. Thanks a bunch. I need to get out and practice this more. You've given me a lot to think about, and I appreciate it. Thanks, Izzy
Just video the first time you connect at 1k and post it! That's what makes it all worthwhile. We had our medic connect on a clay pigeon at 1k...he could've walked on air!
browneye77 Definitely will do! I've been so busy I can't load the damn ammo I need! Soon. . .Izzy
+browneye77 For me, shooting a clay at 500 would be big bragging. That's a small target.
Ha ha ha! Shooting a clay pigeon at 500 is big bragging!
I noticed no one has posted in a bit. You are doing your part by getting out there and getting some trigger time. I'll give you my professional opinion and a few tips. One is load a heavier bullet. Berger or even a monolithic round. The solid copper rounds have a very high BC and the extra weight helps to carry the round a bit farther. They aren't as fast at the muzzle but they hold up better for the stretch. The round itself has a lot to do with the balancing of the weapon. Once you find the sweet spot with your reloads, stick with that load! Second is don't wrap your thumb around the grip. Let your hand rest on the stock and keep your thumb tucked with your hand. Eliminates sympathetic muscle response which can throw the shot off. We can't tell how you are laying behind the rifle so I can't say anything there, but make sure you are loading up that bipod and doing it the same way for every shot. Otherwise keep up the work!
What scope are you using and what are your thoughts on it for the distances you shoot?
The scope is a Vortex Viper ffp 4-16 x 50 with modified mil dot. I think it's a great scope for the money. You might prefer the one that goes up to 24x power, but it's a pretty nice scope with clear glass, and excellent tracking. I think it works great for long range shooting and ranging. Very accurate, as long as your gun and loads are up to the task. Izzy
+2HrLunch I'm getting old, I want about 100 power, but I settle for 24. lol
Not bad Izzy tough distance and target you'll get it.
Good Stuff ! Long shooting is more addictive than heroin. I'll just bet your ballistic calc was dead on for the range but didn't compensate for inclination. It looked like you were shooting uphill. Good vid brother. Subbed!
I like your setup. What kind of rings and base are you using?
That's an EGW 20MOA rail, and Burris XTR tactical 30mm rings in low. Izzy
Nice been looking for good ones. Just bought a gun and the bases I have bent after 10 shots. Made by burris
"Fun" video man keep working it. Next time don't end the video until you get a hit haha!
Love that stock m8
love your videos:)
Take it easy on me its
my first time
Work on the camera work.
