I noticed that.... not many 308's All the more of a challenge....
Were you in Bby when the ranges were open on the Barnet Hwy? I cannot recall if the Barnet Rifle Range had a 200 or 300 yd. pin... That place used to tease me all the time... But I didn't have the firepower back then.. Now its a friggen bike park... smh.
I have to try this challenge.. I'll start my attempts shortly. Never forgive myself if I dont..
I read it was permissible to post failures siimply for curiosities sake? yeah?
I think I have a target that qualifys. I would like to find some one arround here to measure it as well to confirm my measurements or to tell me I didn't make it. And then to figure a way to post it.
Simplest is to so as suggest in the OP "Measure the extreme outside spread of your group and then subtract the bullet diameter" place a caliper on extreme os spread, snap picture. Group size for .308 is measurement - .308
Bullets often cut a smaller hole depending on target material... for a more accurate group measurement the first thing is to measure one hole... write that measurement on the target for reference... then measure the group and subtract the reference mesasurment... that is the way we did it in Centerfire Benchrest before we had a proper tool...
At a shoot you need something to measure the targets quickly and get the results posted on the board... the most popular tool is one of these or similar to one of these. Very reliable and easy to use.

I did, I offered a much cheaper alternative to someone who wants to just try it out. It works perfectly fine for this challenge.
I hope I did my calculation correctly. I measured tonthe outside edge of the two furthest shots and then subtracted my bullet diameter from it. Was just at silverdale today doing my ladder test and got this group.
Remington 700 SPS Tactical .308WIN
Timney two stage trigger
Vortex Crossfire II 6-24x50
MDT HS3
MDT skeleton stock v4
CoreTac Solutions clamp-on brake
The load was Hornady Match 168gr BTHP, 41.6gr Varget, Winchester brass and CCI LR primer.
EDIT: oops. i just realized that i need five 5-shot groups. i guess i will have to try this again later this year. lol

Hey there Chinese Guy,
interesting numbering on your loads. Any particular reasoning for the way you have your tenths organized?
Nice looking rifle too btw. I am considering the MDT setup for my savage 10FPC.
Good shooting.. Looks like a satisfying day out at the range.

Finally got to the range yest. after more than 6 weeks wait for the road/parking lot to defrost from sheet of ice to muddy potholes. YES, Vancouver does get snow once a decade.
Took a gamble, sighted in at 100m, luckily took only two shots. Did several 5 shot groups from min powder, then .5gn increment. Post is the last group using OnTarget Precision Calculator, nice free software, hopefully got it set up correctly.
Just one group, very happy with it. Time to start load development, then off to try this challenge which the rifle seems capable of, not sure about the shooter.

the numbering was because the hornady book said max load was 44.0gr so i did decremental weights by 0.3 from there (44.0, 43.7, 43.4, 43.1, etc.)
satisfying would hardly describe it. i was so cold with the wind that i was shivering while shooting which threw off quite a few of my shots. im going to do another smaller ladder test from 41.0-44.0gr when it gets warmer. it was the first time where i was glad to leave the range. lol

Haha... c c c c oooldddd....
It was like that here last week.. soon as the sun went behind the hills it dropped to sub zero temps. I dont mind the cold so long as Ive got good shoes and good gloves, but last week was about as much fun as your trip sounds like. Looking forward to see what you and your rifle can do when youre warn and cozy!
That theres some nice shootin' Tex.. What range did you go to? Mission or Coquitlam?
Im still gotta get my sorry butt out there.. I want to see if I can get my lakefiled to do this.. then the 223 and then the 308.
lots of fun coming up.. hopefully!
POCO. Nice several yr old wooden shooting benches. Heated covered shooting area. Hot water in the washroom. Kitchen with kettle, stove, coffee maker, bottled water. Target backstops. Just bring your firearm, paper targets and stapler.
Sounds like paradise compared to conditions described by outdoor shooters in other areas.
