garyw Posted June 21, 2010 Report Share Posted June 21, 2010 bob-when i had mine i went down to 23.5gns with rel10 but accuracy dropped right off.i found the sweet spot with a 40gn berger at 24.8 but this gave a bit of pressure so i dropped to 24.5 this seems to be the right amount of powder for the 40gn bullet in relation to case size. i think i gave you some load info when you first got the rifle if not let me know and i will let you have data for 30- 32-39-40gn. gary Link to comment Share on other sites More sharing options...
alled12 Posted June 21, 2010 Report Share Posted June 21, 2010 Given 20 tactical and 20 practical are very similar: 25 grains vit 133 39 grain blitzking lapua match brass federal primer It shoots straighter than I will ever do. I will say I found good accuracy around 24.5 grains of vit 133. Link to comment Share on other sites More sharing options...

Guest Scotland Rifles Posted June 23, 2010 Report Share Posted June 23, 2010 I think i need to have some nice brass to load, I'm not that keen on the Dakota stuff but as its all i can find down here, I'm just wondering if better brass will have the same problems. bob.

Scotch_egg Posted June 24, 2010 Report Share Posted June 24, 2010 Bob, Dakota brass is made by Lapua. I don't think you will get much better. If I recall corectly your rifle was chambered by Dasherman, with the results 6mmbr is getting I would use his OAL and load as a starter for ten. I believe Dasherman built his rifle too. I am having a .20Tac built by Dasherman and with all the research I have done I will be using N133. Reloader 10 has been recommended by Tod Kindler, but the published results I have seen are consistently better with N133. Dasherman informed me my barrel arrived last week, I can't wait to get the finished rifle out into the field. Link to comment Share on other sites More sharing options...
Scotch_egg Posted June 24, 2010 Report Share Posted June 24, 2010 I have just found this thread also regarding excessive pressure in .20 Tac. It may be of help. http://www.accurateshooter.com/forum/index...,3739104.0.html Link to comment Share on other sites More sharing options...
jordang Posted June 24, 2010 Report Share Posted June 24, 2010 what pressure problems are you getting Bob? Ive seen heavily cratered primers in a friends 20TAC (the bloke who started the thread above actually with what I beleive was gary's old rifle!!!!) but thats really all ive come across. Although the virgin Dakota/Lapua brass does seem to be a bit tight the quality is excellent - I weighed and measured my first batch and it was very consistant. I havent bothered with the last 2 boxes and have had no problems other than the tight necks. That said I have been using a mild load!! Once this N133 is gone im trying a few different powders with the once fired, neck sized brass. There seems to be alot of powders the cartridge shoots well!! there is alot of good info on the saubier forum too mate. Link to comment Share on other sites More sharing options...

I also find the ones with the primer problem also seem to be a weeeee bit tight on the way out, i think i will really have a good go at checking everything on my next batch of 50 and see where we go from there. thank you all for your help and support update to follow. bob.

20Tac Posted June 25, 2010 Report Share Posted June 25, 2010 Hi Bob I was using 24.7 10X for a while - I have run loads slightly higher than this on neck sized once fired brass. Are these pressure issues with new brass or once fired? Have you tried neck sized only cases - the pressure does drop slightly due to the slight increase in case capacity, depending on your chamber size. I'm now using up a batch of N133 with 40gr and 32gr, though the velocity will be slightly lower. Have you also changed the seating depth - that might help.

Dasherman informed me my barrel arrived last week, I can't wait to get the finished rifle out into the field. Your right Dasherman did build and chamber my .20 TAC the only difference is mine is a 1 in 9 twist Pacnor. This shoots the 50 grain Bergers superbly. My main load as said earlier was 23gn N133 this is superbly accurate and adding any more powder does nothing for accurracy. I've had no problems with the Dakota brass other than loosing one or two to split necks after multiple reloads. Mine shows cratered primers on almost any load and I think is more of a problem of the diameter of the Remy firing pin, I believe if I had the pin turned down and the bolt bushed this would solve the problem.

Sakoboomstick Posted June 26, 2010 Report Share Posted June 26, 2010 bob im running 23gn of n130, had very good results, im keen to try reloader10, ive got a couple of tubs sat here, i tried the 10x on 35 gr bergers a while ago but wasn't that happy. i have had no issues with he brass from Dakota either, ive only just started reloading with once fired cases, the first 1200 fired as virgin brass have been great.
