300m ISSF prone and 3 position

Recommended Posts

After shooting ISSF air rifle and smallbore competitevely since 2001, and dipping my toe in F Class last year, I decieded  to build an affordable .223 Rem 300m ISSF rifle. It is supposed to be affordable with affordable amunition for a casual shooter. I'm building a T3x Tikka in a custom stock with Walther sights. According to ballistic calculator with 80gr Sierra @2800fps I will be giving up around an inch of wind drift in 4m/s (10mph) wind compared to factory 6mm BR Lapua. It doesn't seem too bad... Will see if it shoots :)

Interesting project Michael


look forwards to seeing the results - stock looks not dissimilar to Sig 205 Phantom in design

Looks very business-like............223 with 80 grain bullets at 300yds should produce some good scores. My 223  is based on a Tikka M595 action with a 760mm 8 twist barrel.

It shoots 80 grain SMK's very well at 600yds. MV 2900.

Hi Michal

Nice looking stock, a bit Walther anatomic. Any testing yet?

I've now done my first tests on my 300mt .223 project, sadly the only date we've had so far this year at Bisley (our only UK 300mt range) was on 16th/17th March when the conditions were not ideal for a light calibre, shooting on a very tight target, in fact they were horrendous, with gales all week end, and the range on safety shut down warning, so a bit of a trial!

BUT, I was impressed, as a .223 virgin, I was impressed with the low recoil, and surprised by how it behaved in the at times crazy winds, in fact I also shot with my 6 mmBR as did my wife, and it was very similar scores, and wind responses. I did shoot a full 60 shot match on the Sunday when the conditions were just very difficult, as against crazy, and with reasonable results, not a lot below what I'd expect with my full 300 mt set up in those conditions.. That was also with not ideal ammo, in that I used the GGG 69 gr match, as the GGG 77gr match is not yet available in the UK.

Although my wife and I shoot 300mt seriously with 6mmBR Keppeler 300 mt rifles,  like you, this project is to see if it can be shot to a standard with a cheaper, but still top class rifle, a Barnard/Bartlein, and using factory ammo, as the GGG 77gr is priced near enough what it costs to reload with high spec materials, and save the hassle of reloading as an option for newcomers to the discipline.

I'd like it to shoot to a good standard with the GGG 77gr, so will try that as soon as it arrives, but if its not available or does not perform, then I'll reload, and it would be with 80 gr Siera's, but a wait now as the ammo is not here, and we don't have a date now until the end of April.

I'm glad to contribute to this 300 mt post, and if any UK shooters would like to try the discipline they are welcome to contact me and I will be happy to advise. And just so they know the types of gun we use, attached are pics of our 300 mt 6mmBR Keppelers,  and the Barnard .223 project rifle, the lurid shades of purple rifle is my wife's!

Have fun
