The gun is good for a repeatable 0.25" @ 50 yd so....
For what it’s worth - for the last five years my gun club has held a combo 100/200 yard rimfire rifle match. At the beginning we separated the 2 matches so anyone could compete at 100 yards - all rifles had to be magazine fed, no tuners, no one piece rests. At 200 yards, shoot what ya brung. The targets have varied at 100 from golf balls to Tums to 20 ga. shells laid on their side (because we had so many clean score ties). The targets at 200 have remained unchanged, the old golf ball. Each shooter shoots 2 relays of 10 scoring shots, score being total hits of the two relays. The ball must be knocked off the rail! Initially, a total score of 4 or 5 would put you in the money. Last month, one of our regular shooters ran 17/20. Lots of fun and vocabulary expanding.
I was trying to find the tune for my 40X with a Harrell tuner and a bloop tube that threads into the Harrell that was cut to length as prescribed by Tony Purdy - PRX. and I decided to shoot at 100 yds for the first time.
The ammo tested was Midas+ and Center-X sorted by rim to ogive length (25 on the gauge). The groups are 5 shots at 100 yds off a rest and rear bag. All the Center- X groups are 1” or less.
200 on the tuner was good previously with Black box so I started there. The bottom row is with the bloop and different settings on the tuner.
Strangely or not, a setting of 416 on the tuner with the bloop and sorted Center-X shoots way better at 50 yds - 5 shots consistently in the 2’s.
I haven’t shot that tune at 100 yds.
I shot more than a case of pricy ammo and spun the hell out of that tuner to get this far. A 2oz trigger tightened the groups quite a lot.
Now I’m lookin to get a bloop tube for the Harrell that is adjustable for length. That’s gotta be the ticket or another gizmo to spin...
I have not read every post here, but I have read enough to see that the ability to read the condition, and consistently shoot in the pick up, let down, or lull will be the determining factor. And the ability to do that only comes thru practice and keeping range notes. I'm still learning.
Use the rifle you have and learn it....reading the wind is is harder.
I got into rimfire to practice for ELRS with 308 & 338 LM, then I got hooked. I bought a used HB Savage MKII in a Tacticool stock scoped with a 4-12 Bushnell from Japan(now a 36X Sightron) all for $275 on RFC. This was whem ammo was tight & everyone thought TAC22 by Norma made by RWS was for 22lr ARs. 1st box I shot 10 5 rd groups at 85 yards, each group was good but each new one was a bit better & the last 5 shot group was .198 C-C at 85 yards. I now own 50+ rimfires & shoot golf balls at 300 yards. I have a range outside the back door on our farm so I shoot alot. I buy 10 cases of 22 a year. This year it was Aguila Std Vel for $150/case. The Savage has close to 100k rds & still shoots great. Maybe I got a unicorn or maybe it's thinking thru every shot doing it right over & over & over. I have targets at 85,100, 200 & 300 yards & plan to move out to 500 next spring. As in many sports I've done like motocross, flying antiques, mountain biking, scuba, etc it's about 85% personal skill & 15% equipment. I did a mtn bike race in upper Michigan called the Ice Man Cometh & saw guys on $5k-$10k bikes get smoked by this guy on a Sqwinn with a baby seat on it. I havent even scoped my CZ precision or Tikka or many other good rifles, I just shoot the old Savage & only clean when the accuracy drops off. I just bought 6 Athlon 4.5-27 Ares scopes while on sale & a 1959 Marlin 99 semi auto(same vintage as me) for $170 OTD as I put in 5 dueling trees at the ranges listed & what a blast. My shooting buddy & I bought Webley & Scott bolt actions when they were about $180ea & he scoped his up last week & we sighted it in then were shooting these spinning targets that were supposed to drop in slots facing you but kept ending up 90 degrees from us so we had 1/4" at 85 yards to hit. he did 5 in a row so I tried & did 5 in a row. Luck? Maybe but I think practice & slowing down & doing it right was the key. He's 70 & I'm 60. Maybe he got a unicorn too I don't know but it sure is fun spinning golf balls on cord at 300 yards. If you get near Kalamazoo let me know & if the weather's good we'll shoot. On the Tikka I'd check the headspace, play with the torque settings & borescope the barrel before throwing $$$ at it but that's just me, Good Luck!
Using wind flags helps ALOT.
In regards to the question “what is the real word repeatable accuracy of a 22lr @ 100 yards”
My personal requirement for a top end rimfire rifle is 100% consistent sub 3/4 MOA or less. Over the years I have owned many rifles that would do this very easily. Please keep in mind that I am talking about how I shoot my rifles on decent days, if the wind is gusting and switching over 5 MPH or the air temperature is below 25f-32f the game changes. Also an important note I am not shooting factory rifles, they are all custom built with no expense spared shooting premium ammo. I have only owned 1 factory but rifle that would hold this level of accuracy, a Sauer 200 STR with the Sauer 22lr conversion.
Oh, I also only shoot prone off a bipod and light weight TAB rear bag. I may be limiting my rifles by doing this but I’m not a benchrest shooter...
The best group I ever fired was from a (then) Sauer TR 202 rimfire conversion. Eley Benchrest gold. One .22 diameter hole.
They are such a nice rifle, I wish they were more available here in the US.
Shooting Smallbore F Class you need to able to shoot 1 inch consistently at 100 yards ! The 10 ring is 1 inch. Everything inside the ring without cutting outside edge is an X. Everything not touch the 10 ring line is a 9. The 100 yard target is a A-33. Most competitors can hit this target, and can do it fairly consistently with 10 shots per record bulls eye. It's a wind reading skill with an accurate rifle/ ammo combination. This is shooting off of a bi-pod or front rest with rear bag on the ground. I would say most are full custom rigs with a few stock Anschutz. Attached is one of the very best 10 shot groups. Second one is about the genorous norm.
That's impressive. Now I am thinking I may need to go custom on the bbl after all. thank you for posting.
@rmist ... you just convinvced me to go ahead with an F-class build (even tho I refuse to use one of those mega $1,000+ rests )
I use a bi-pod...it's a SEB Joy-Pod...Nothing better ! I shoot the F-TR class not Open. Plus don't want to lug around all that extra weight either.
Yeah, that looks interesting, tho I love my Atlas 'pods.
I was hoping you might show some of your targets in this thread. Reading the wind, reading the mirage, properly tested ammunition to match the barrel is the key.
A couple more at 100 yards during competition. All but one are 10 X's. With ten shots per bull.
This 10-shot group measured under 1". Do your ammo testing on flat-calm days. Once you find the best ammo, put a tuner on. You will then have to spend a small fortune finding the tuner setting. If the .22 ammo makers were smart they would GIVE a Harrel tuner to anyone who wants one.
So you wanna see where the rifle shoots decent without the tuner then put it on and play with it from there?
I just got on the waiting list for a 2500 Trident.I have a Harrell’s tuner and weights coming also along with 2 HV 29” Kreiger blanks.This will be for a TR and also dabble in some BR.
Question... Why waste valuable ammunition without a tuner on? If you're not going to put a tuner on at all then by all means test without! If planning on using one then your just wasting time and ammo!! Set the tuner at zero and test lots. You can tell very soon whether or not it's going to work in your barrel. If it looks promising then move on to other tuner settings.
IMO, I'd use the weights last. I did try them after I had a very good tune. The weights actually made my barrel shoot worse.
Actually my suggestion was made to avoid wasting ammo, but maybe there's a better way to skin the cat.
