I drill and tap the muzzle end, its fast and makes a secure connection when sealed with something like a Dowty washer. You will be removing an inch of the muzzle at least anyway so it doesn't cost you anything.

OK so heres a question. Could barrel to action torque have an effect on barrel harmonics and ultimately accuracy? I dont suppose any of use would expect much from a hand tightened barrel on a match rifle so could there be an optimum torque? Or more likely could there be a minimum that we need...

Guys, Is there any reason why I would not be able to lengthen the neck on my existing Dasher chamber to run the new Norma brass? My existing neck is .271" and I have a .272" chucking reamer that Im thinking would be fine with unturned Norma Dasher brass? I dont want to throat again so the...

Thanks for your input guys, I have made a tuner that weighs 12oz for a 30" 1.250" diameter barrel. My current load for this rifle (105Hybrids from a 6 Dasher) is decent, 5 shots into the mid 0.2s but I will try the tuner on with that and see if it can be tuned any? If I do any new load...

Confused... Guys, Can you tell me where I introduce the tuner? My load development usually consists of an OCW test where I monitor ES and assess the bullet/powder combo by looking for a stable POI, when happy I choose my OCW then fine tune things with a seating depth test and then once I find...

Tuner Applications? Thanks for a great thread guys, as always it has raised more questions. Are there certain applications where the effect of a tuner is more noticeable and has a greater effect on results? For example; Would a tuner work just as well on a 1000yd heavy gun with a 1.250"...

Guys, Im looking to make a muzzle brake for a 600/1000 yard bench rest light gun in 6.5x47. Ive never made a muzzle brake before, I see the pepper pot style and also others. Is there any info out there regarding what if any types have a detrimental effect on accuracy and what dont, best shapes...

Guys, I moved this subject to its own thread so as to not lose it in this one. http://benchrest.com/showthread.php?96835-Setting-up-the-bore

Great question Dave and one which deserves a thread of its own I feel.

You dont have to live in the US to have the right of an opinion and Im certainly all for that. I f you have a machine and a specific requirement that allows you to replace the compound with a solid tool post then again I have no issues in that regard if it works for him. My issue is how he makes...

Im now questioning how we ever managed with frail compounds for all these years. On any lathe the compound and/or the tool post is quite often the least rigid part of our tool holding set-up yet I still manage both heavy cuts and good accuracy with mine as will most others. Sometimes I see...

Thats pretty much where Im at now with my thinking.

Thanks for your thoughts guys.

Yes, I would agree Jerry but if your tailstock centre is very close then it shouldn't be an issue. I check my tailstock about once a month by turning between enters over 18" - taper is kept to less than 0.0005" over that distance which would mean much less at the distances between centers that...

With respect Al I can't discuss anything with you, you ramble or talk in riddles far too much for me :)

I dont disagree with this at all. That said my question was about what you describe as a slight amount of oversize, I wonder how many rifle builders actually check for this? I see lots of videos showing low runout figures but nothing about oversize. Ive chambered a couple of barrels since I...

I clocked the reamer Mike as you suggest, unsupported but pushed to the bottom of the chamber and with the stylus maybe an inch from the chamber mouth which I guess will also give a bigger reading that the chamber mouth. Interestingly I cut another but this time I didn't apply any preload on...

Could I ask in which cases it would be enough to be significant as you used the term 'most cases' rather than 'all cases'

OK, thanks for that Jerry. I dont build bench rest rifles, Im more into long range varminters or accurate hunting rifles where brass will be specific to one chamber and never need to be interchanged. I figured that it shouldn't make any difference to anything as the brass will form to its...

I understand and accept that the idea is not to have our reamers cutting oversize but please humour me guys, how much oversize, if any would be acceptable? I ask this because yesterday I tried cutting a chamber on a scrap blank end using a collet chuck in my tailstock to hold the reamer instead...
