looks very nice, that kal fella seems to be very handy at this duracoat business, I wish I could finds something that needs coated.

It certainly looks a very good job indeed (bedding, end cap and Duracoat)

 

 

Well done!!

I saw this action at Kal,s the other day...and very nice it was indeed. You will love the 6mmbr matey, its a wonderful cartridge.What twist did you go for?

Pretty specialised then Col. Mine is also a 1 in 8". I had it specifically set up for 105 berger vld,s and its benchrest accurate with them, but i think you could maybe get down to 90 grain heads with this twist, and i may try it myself sometime. I assume its one of Steve,s? He was in the shop friday, came for some stocks. We had an interesting chat about the 6.5 grendel, as he,s applied for a reamer license from alexander arms. I think it will be a very interesting cartridge.Its not doing great in the ar15,s as i know a couple of lads with them, but they cant stoke the case up to its proper capacity, because they dont extract from a straight pull when they do. However, a bolt action will be an entirely different kettle of fish, only drawback to it, is its ppc bolt face. It would make a smashing roe round i reckon.

hi Dave

 

its not a S kershaw, its a long story and not one i would want to bore everyone on here with.

if you had your reamer specked to the 105g VLD then its the same as mine and will shoot down to a 75g V max bullet, we have been getting good groups with this combo, 87g v max as well.

the thing is with a 105g VLD is they have a Short bearing surface, and this lets you still reach the lands with the 75g bullet and still have enough bullet in your case, this was the reason for specking my reamer this way.

i have not tried any smaller heads than this,so I'm unsure how low you can go.

the 1 in 8 should have no problems stabilizing the bullets as well,

 

Steve did the bedding and the barrel re profile, re set the head space, kal did the dura coat and i did all the running around,

all work was done at cost to me,so i should not really take all the thanks.

Steve did the work in super fast time,1 week to do all the work,and he did it after he should have finished for the day. and agreed to me doing the job for trade.

kal all so did the same for me,he all so advised on the colour and got it spot on as sako loves it. and it is much appreciated.

Your comments about the reamer throated for 105 vld's and lighter bullets have certainly given me food for thought Colin.

 

I have a .243AI reamer that is throated for 105 DTAC's, but if I could use this for lighter bullets is may be able to perform double duty............

Quite right about the 6.5 Grendel not working too well on a straight pull AR Platform. I am having a 6mmAR built at the moment on an AR Platform but already have a 6mmAR Remington 700, it is very accurate. The 6mmAR is basically a necked down Grendel an will take bullets all the way up to 107 grain SMKs, the heavier bullets don’t work to well on the AR as they are restricted by magazine length.

Hi Ronin

 

David Tubb does not make a 105 DTAC, he does do 115s, a new boron coated 117 plastic tipped bullet and I think I read somewhere recently that he is developing a 111 grain bullet.

 

I was shooting 115 DTAC this weekend in 6XC, managed to get 3025 FPS average velocity with 39.9 grains of N550 (6 shots over a chrono ES 10, SD 3, AV 3025, 30” Mike Rock 5r 1 in 7.5 twist barrel). The round only needed 24 minutes elevation from 100 to 1000 yards and I was very pleased with the way it shot but will be doing a little more load development and tuning.

you are quite correct, those pudgy typing fingers again :lol:

 

The 115 Dtac performance is very good from your figures, 24 MOA is not much indeed - what is the BC at that MV?

 

My reamer is specced: .243 AI, .270" nk and .140" free bore - Col, could you advise on FB length of the 6mm BR reamer you used, I would be interested to know the difference bettween the 105 and 115 bullet set up.

 

Cheers :lol:

hi ronin

i will see if i can dig out the drawing,PT&G normally send out a drawing with the reamer,but I'm not sure if i have one or not.

I found this from another forum; posted by Robert Whitley

 

" It depends - if you are working with a 1 1/2 degree throat angle, a .165" freebore is about right for a 115 DTAC. If you go with Tubb's 3/4 degree throat angle, you would typically use a .123" freebore for the 115 DTAC. "

John, Colin

 

thanks, it is a PT&G reamer, but I havent the print as it was bought from a friend who used it once for a project.

 

It may be a compromise bettween 1.5 degree and .75 degree throat angle as it fits neither spec - it did work exceedingly well in the last chamber though ;)

I would estimate the BC to be somewhere between 0.585 to 0.595, my bullets differ from the published data available in that I re-point, trim and re-point them; it is supposed to uniform the BC and add a few extra BC points.

Not wanting to be funny but where did you send it to be reproofed?

 

I ask as a good friend has been waiting something like 3 weeks to get his 300wsm done.

hi harry

 

we don't send them anywhere.

 

we only take them in by hand, IE i will not post them.

i use Birmingham proof house,and i have never en counted any wait of that degree.

you can ring them direct 01216433860

and they will normally fit you in next day or the day after.

depending on how many rifles you take in,will depend on how long you have to wait.

about 1 hour or 2 will normally get the job done.

it costs a bit more but it is worth it to me and my customers.

 

a back street metal fettler is all ways happy to help. ;):( may be he should have gone to a real rifle smith,and had it written in to the contract.Caveat Emptor! :D:lol:

but as i say,i am all ways happy to help.and that extends to you as well harry ;)
