    For my best shooting with the freedom arms
    On bench, very firm 2 hand grip but not so that you are compensating for muzzle lift. Concentrating on grip squeeze. Hands resting on a pad. Front of barrel is on a rest but barely touching it. Just enough to steady aim with light contact

    I actually have to write this stuff down, firearm to firearm as change in hold has significant effect on outcome

    I had been preloading my Atlas, but likely too much, I have not been preloading it all all lately, but that might explain some of the vertical I have been seeing. Maybe a light preload is the way to go. I am still learning shooting from bipods, I always shot off of a front rest until not long ago.

    My old Benchrest setup. I built the box for it, and would bring it all down to the bench in the box.

    216.4 yards, cci standard velocity, offhand 2 handed ruger single 6 with irons. took about 30 shots.

    I had to put 4 clays around it to see the darn thing. By the time I popped the container, I was down to 1 clay left to see. Distance shooting is so much fun with .22s.

    Yep, long range with rimfire is a hoot.

    I've seen it more than once that shooting .22LR out to 200 and 300 yards is much like shooting .308Win out at 800 to 1200 yards. And yeah, wind will blow the bullets off target in both cases. But learning to read the wind and compensate is part of the fun.... I can't do it worth spit... But I do appreciate trying to read it and guess. It's practice after all. Can't get any good at it unless we dive on in.

    My 300 yard data for 22LR matches about 675yrds with my 308win 165 ELD load. 123” drop, 12” drift in 10mph wind.

    I just found this thread. I have a nice Kimber K22 that I haven't shot yet, but just picked up a Bergara BXR001 last week. The Leupold Mark 4 3.5-10x40mm has +15.4 milrad of vertical adjustment sitting on the 30 moa integral rail and with a 50 yard zero. This should get me to 300 yards but I can use the Tactical Milling reticle for an additional 5 milrad holdover which should get me out to 400 yards. I've never shot a .22 LR beyond 100 yards, at least I don't think I have, so I'm looking forward to seeing what this rifle will do.

    I ran some numbers today and this is my starting point using SK Long Range Match ammunition which is subsonic.

    50 yards > 0.0 mil
    100 yards > 1.8 mil
    150 yards > 4.2 mil
    200 yards > 6.9 mil
    250 yards > 9.7 mil
    300 yards > 12.8 mil
    350 yards > 16.2 mil
    400 yards > 19.7 mil

    From my experience in shooting 22's the accuracy in ammo varies enormously. What's the best ammo fairly easily found without having to purchase it online?

    Is there a book or other resource that explains how to arrive at these numbers?

    Any ballistic calculator should work. Many online - Google search it.

    Just need your muzzle velocity, ballistic coefficient, and environmental conditions, and run it all through a ballistic calculator. There are several available online or as free mobile apps. Hornady’s is very good, and free.

    Hornady Free online ballistic calculator

    Here’s a table of some ballistic coefficients for various 22LR ammunition.

    This post reminded me of my Ruger Standard Auto that I mounted a 2.5X Weaver on, back in the 1960s. One day I was walking around the woodchuck fields with the pistol and a rifle and noticed what I thought was a rusty can about 100 yards away in a hayfield. I decided to plug it with the pistol, bracing against a small hardwood. I shot and heard a weird sound...more like a "plop" than a "ding", so I went down to check. I was amazed that the large "can" turned out to be a dead woodchuck...freshly shot through the head. Ruger Auto Scope.jpg

    The ballistic calculators a chronographs and a BC can get you pretty close.

    You can also just shoot and note the amount of drop you actually get.

    My buddy I was talking about in the earlier post was down again recently. Interested in playing some more, he brought a 4X8 sheet of coroplast and we put it up on an adjustable stand I have. This is it on the left of the gong target being shot (with 405 grain subs that also have a rainbow trajectory, you can see the amount of elevation compensation for the rifle zeroed at 100).



    Then you just need a good rest so you can have the rifle setting where you were aiming and drive the reticle to the point of impact. Good idea to record the number of clicks, if you are wanting to go back. Pretty much like this.

    While back, i mounted a vernier tang sight on my single shot win mod 67a. Was a blast hitting 5" square plates at 200 yds.

    @Varminterror, that's some useful information there. I use a couple of ballistic programs but was using Exbal yesterday to back out the BC of the SK Long Range Match bullet shown in the link below. I tweaked some values until the numbers were close to those provided by SK and the G1 BC I ended up with is 0.16 which isn't too far off some of the numbers in your chart. SK used a 26" barrel for their data whereas I'm using a 16.5" barrel with a suppressor, but I'll shoot at 100 yards and 200 yards this week to see if my numbers are close. I have a LabRADAR so will measure muzzle velocity. I have the accessory microphone for that unit which will help since the noise signature with suppressed/subsonic is very low.

    @MCMXI - I forget where I found that chart - I’ve had it saved on my phone for years, but I’m fairy certain I just googled “ballistic coefficient 22 LR”.

    Years ago, when doing gun repairs for a business, I had to sight-in a lot of rifles, often after mounting scopes. I bought a Sweeny Site-A-Line, which is a movable rifle vise with rubber feet. After verifying mount tightness, I'd take the rifle to the range and shoot one shot from my benchrest setup, then I'd clamp the rifle in the Vise, adjust the vise vertically and move it on the bench (horizontal adjustment) to get the reticle centered on the target center, then adjust the scope's reticle to coincide with the bullet hole or other impact point desired at that range. Then I'd fire a couple of shots to make sure the bullets actually hit where I wanted them to in relation to the bullseye. (Most people wanted theirs to hit center at 100 yards.) After I was satisfied that the rifle was hitting where it should, I'd fire a few more shots to confirm the setting and check that everything was working properly and that the settings weren't wandering. The nice thing is that scope, mount or rifle problems could be found rather quickly.

    Recently, I used the vise to check-out a friend's rifle and discovered that the base screws were relatively loose, so fixed it at the range and completed the sighting-in.

    I was shooting Rimfire Benchrest several years ago and the ten ring is 1/4" and the "X" is just a Dot. Recently, a perfect 250x25X was shot at our club range which is the first time one has ever been shot...by a guy I know. I once fired two 250s and a 249 and the X-Count was in the teens. That was the best I'd ever shot, with the only 9 being on the last shot of the last target. This competition is shot at 50 yards and considering the price of ammo, I never tried shooting that rifle at 100 yards, because there's no point in doing so when there weren't any competitions at that distance.

    Note that the scope was a K 2.5 with about 3" eye relief. We didn't have special pistol bases back then, so I mounted the scope off-center to the left, so I could use either iron sights or the scope and could remove the scope and not have the bases block the iron sights. The other weird thing was that I turned the scope so the reticle was an "X" instead of a cross. It worked well, except sighting-in was a bit weird. Kind of innovative for a high-school kid in 1963. BTW, the grips were made by Fitz and they had a large thumb rest.

    For long range, is the consensus that supersonic ammunition is better than subsonic? Running some numbers, a 40gr bullet at 1,600 fps with a G1 BC of 0.15 goes transonic between 100 yards and 125 yards.

    Used to spend some time shooting golf balls at ~230yds. Don't have any pics beyond that of one of the rifles. When I really wanted a challenge, I'd shoot at paint cans with the iron sighted Single Six.
