Take a fired cartridge, clean and size it, then cut a couple of slots in the neck as shown in the image below and remove the burrs, a nail file is as good a toll as any for this. Now pop a bullet in the end leaving it sticking out quite a way, place it in your rifle and close the bolt carefully, open the bolt, catch the bullet and you *should* have a round sized to your maximum OAL. Measure it and repeat the process a few times to get an average.
S'easy!

Yeah, I'd seen that method in the post i linked to earlier about excessive chamber pressure:
I need to be able to cut the bullet, i was thinking the more accurate the better.... and the hacksaw I have needs new blades, and even then I don't think I'd be very accurate with it!
I'll see what i can do, but thanks again for the heads up on it... definately something I'll be having a go at.

When you didn't post yesterday, I was concerned you'd had a 'wash out'...but it looks like you got away with the weather
Considering you guys were shooting at a small target (in the aperture) the results for the 46.5 look really encouraging.
You can operate those targets with one person - So you could take turns shooting at the correct 100 yrd target (would tighten up the groups), and marking for each other. You can buy the marking bits and bobs very cheaply, and score cards are only pence (can photocopy a few for load testing), and you don't need a spotting scope - any half decent binoculars will do....
Keep us updated - Now you know your 'zero', I'm looking forward to seeing the results at 300 yrds...
Yeah, we sent my gf down to the butts to mark for us, but it was just whilst we were zeroing enough to be able to get on target so we actually hit the paper plates.
Speaking of, I'm not sure if its worth trying some development of loads a bit more powerful - these were about a 5 inch drop lower than where the RG rounds were coming out on the test target - atleast in Mo's rifle - maybe a 3 inch drop in my rifle. any suggestions as to why this would be?
I think I'll need to borrow a chrono at some point!
300 yards will be fun, if we ever get to go do it! haha, I'm not sure when the next shoot is, although we have our clubs open competition coming up in august which should be a blast! hopefully me and Mo will have the edge on competetive ammo! haha!
when I'm home next I'll have a look for my previous scorecards (there arent many!) - I think I've only ever shot 300yds with Mo's rifle - when i went to Oxford open (the only time I'd shot my RPA not on a zero range) we did 400, 500 and 600 yards....
...need some serious wind coaching to be able to tidy it up though... I didnt have any misses, but I came 1 but last!

Well done to TattooedGun for taking it all in and taking it all to the range and posting a report.

:goodjob:
no Probs :) I'm sure there will be many more posts and questions and stupidity from me yet!
Thanks again to everyone whose helped me along the way so far!
If we'd have got to the range without any help from you guys I'd be shooting dangerous loads at god knows what targets :)
:lol:
It'll take ages and take it out of proof
