Anybody shooting a 22 BR in long range matches? I'm looking for bbl twist rates, bbl length, velocity, bullet length, and powders used for this project.
22 BR for long range
- Thread starter Chinbullco
- Start date
I have a few 22 br's and I shot a bit of F class this year earlier in the summer.
The one I shot had a 26" gaillard barrel LV contour 1-14 twist I shot it at 300 400 and 600 meters.
I shot four rounds at a match and scored 198 and I think 28 V bulls .
Then one calm day at the range I played around with it at 685 yds and shot 3 targets consecutively 3 shots per target and I was holding about 2" groups.
I was using some H322 30Gr behind some 52gr amax.
Right now I am looking to rebarrel one of my guns to 22 br with 1-7 or 1-8 twist so I can shoot the heavier bullets cause those little 52gr bullets get blown around all over the place if the wind picks up after 300M .
I think the 22br is a great and very accurate little cartrige and a beauty to load for excellent case life c
heap to load and power to boot.
I played around a bit with a 22br with a 1-7 twist barrel a few years ago and was shooting some 75 gr and 80gr bullets I tried varget and H4895 they were both good powders 4895 a tadd bit better at 200yds I was holding about 1/2" or so.
This thread should be interesting it might make me make up my mind between a 1-8 or 1-7 . I will probably go with a 28or 30" barrel for length and heavy varmint profile.

H4350, CCI 450, Lapua 6mm BR brass, 90gr Berger VLD.
In a 28 to 30" 7 twist barrel, expect to be around 2900 to 3000ish fps.
Based on BC calculations, better LR drift then the 6BR/105gr combos.
Has proven to be very accurate.
Lower recoil, bore life should be a bit shorter then the 6BR.
Nice combo.

To my mind, if building for long range shooting, you will want to take advantage of the 90's. Exceptional Ballistic Coefficient, and like all Bergers, they are very well made. The "problem" is you should throat specifically for these bullets.
28" is plenty of barrel length and if I were building one, I would go with a 7" twist, although I have had feedback from a few shooters that are using 7.7" twsits and having outstanding success.
H4350 seems to be the powder of choice along with a CCI prime - especially in a customized factory action.
I have seen and heard of these guns doing VERY well, but my only criticism is like any one-hit-wonder bullet, if your gun don't like 'em, you are kinda hooped.
Fortunately, I have never heard anyone say they couldn't make them work, and to my way of thinking this is the quintessential 90 grain berger cartridge. Mystic is right... their velocity and BC are better than a 6BR. The 22BR has it all.

22 BR long range
Any 1000 yd. results? I guess if its capable of 2" 600 yd. groups it should be a contender at 1000 yd. Is there a better cartridge choice for a long range 22 cal?

Go bigger. 22-250 or 22-250improved.
Compare the numbers with the faster 7mm's and you will find this little slug can keep up when launched over 3200fps.
And yes, the bullet will survive that speed. Built a 22-250 to test this and had no issue going 3200fps. The 22-250 improved might just squeeze a bit more speed.
Barrel life will be short but that is par for the course these days.

22-250 or 22-250 AI
Have had a number of 22-250's over the years and found every time they're fired the brass has moved forward, improving the case would halt that. I will go with the BR case and 1 X 7.5" twist bbl. If this doesn't work the 22-250 AI will be the next step.

How much fine accuracy can one get with a 22-250 I have played with both the 22br and the 22-250 and I find the 22br to be more accurate .
If you take aggs from a 22br and compare them to aggs you get with a 22-250 the numbers will speak.
I am not saying the 22-250 isn't accurate but the 22br is just more accurate IMO.
Maybe at those extra long ranges 1000 yds or so with lots of wind the extra 200fps would be nice but on a regular day I feel the br would come out ahead.

Absolutely correct, the PPC and BR family definitely edge out alot of chamberings on a pure accuracy basis (especially at shorter distances) BUT this is F class and distances can get long and winds have been known to blow.
By BR standards, the targets are large but very hard to hit given the atmosphere in between and lack of adequate wind flags.
So reduction of wind drift is very important. here we can go into all manner of debate but the trend is certainly and quickly moving towards large cals pushing the highest BC bullets as fast as barrel and shooter can tolerate.
the other end would be the push the 22cal 90's as fast as they will go to try and mimic the wind drift of the larger cals.
Will this yield the most accurate rd? Usually not but these will be the most forgiving in the winds and we after points not group size.
F class is all about INSIDE 5's VS OUTSIDE 4'S. That would be what 200fps is worth to you.

Long range 22
The 22-250 AI is an option now with Lapua brass available. Think a barrel chambered for 22BR and another for 22-250 AI would be a good way to proceed. I'm doing both, thanks to Mystic.
