Woodlander Posted January 18, 2018 Report Share Posted January 18, 2018 I currently use Fed Match primers for my 6br,along with Varget. I'll be looking to develop a load using N140 and this may be a good time to try a different primer. Ive heard of groups/ES tightening up just by changing primer,anyone experienced this with a 6br, or any suggestions as to a preferred primer for this chambering.

baldie Posted January 19, 2018 Report Share Posted January 19, 2018 I've always used BR4's. I think you will find 140 a bit slow. Link to comment Share on other sites More sharing options...
Woodlander Posted January 19, 2018 Author Report Share Posted January 19, 2018 Ok Dave. I'm shooting 105 Amax, for a while anyway,out of an 8 twist,which powder would you try, or should I buy up all the Varget I can get my hands on? Link to comment Share on other sites More sharing options...
Re-Pete Posted January 19, 2018 Report Share Posted January 19, 2018 I use Murom KVB-223M's..............RS52 powder, and Scenar 105 L's in a 30" 8 twist barrel. MV around 2850, and on a good day will do 1/2 MOA. RePete Link to comment Share on other sites More sharing options...
The Gun Pimp Posted January 19, 2018 Report Share Posted January 19, 2018 Most of the guys using 6BR for long range benchrest (including the current record-holder) use Vit 150 with a 105gn bullet. But the 'soon to disappear' Varget will also work very well. M/vs are usually in the 2950 range but this will be from a 28 - 30 inch barrel. Primers?

Thanks Hi,,,nothing wrong with Fed Match primers but by all means experiment. I have read many times people have found the BR4,s give better all round results but I reckon its all to do with the whole "tune" not just a magic primer fix.I have not tried any alternative I must admit but with Vit powders and Fed match I,m not looking for much more from by 6BR,s,,,,,,,Hopefully I,m attaching some groups of 90 Bergers with Vit 135 and some 105,s with Vit 140 all sparked by The Fed,s. This particular rifle gives me a huge window in which to play,,,but I,ve had similar results with previous builds,,,,,here we go,,,,,, Forgot to mention the 105,s are doing 2825 with the 30.5 load in the 25 inch barrel.l Link to comment Share on other sites More sharing options...
poacher Posted January 21, 2018 Report Share Posted January 21, 2018 Hi guys I am shortly to start reloading a 22BR for a friend who is fairly new to reloading so am assisting him develop a load for a new rifle my question is would the cci br primer work as well with the 22 as it does for the 6 or should I just start with standard primers ? Do any of you have any experience to impart pls The 22 BR is new to me too I shoot the 6mm ppc so any experiences any of you have would be welcome Many thanks Steve Link to comment Share on other sites More sharing options...
Chris-NZ Posted January 21, 2018 Report Share Posted January 21, 2018 I'm surprised no-one has mentioned the 450 primer. It's known to work well in 6BR. I prefer to use the same primer in my BR and the 6- and 6.5x47s. Keeps it simple and it works. Link to comment Share on other sites More sharing options...

The only difference I can see is the massive difference in price. Link to comment Share on other sites More sharing options...
Woodlander Posted January 23, 2018 Author Report Share Posted January 23, 2018 Thanks for all the replies and Laurie's article on primers is,as you would expect,both exhaustive and very informative. I'm going to try some BR4s and see if I can tighten up my groups cheers Link to comment Share on other sites More sharing options...
17 Rem Posted January 24, 2018 Report Share Posted January 24, 2018 I use BR4s in mine. I once tested them against Federal GM205Ms out of interest. The BR4s were noticeably more accurate and the chronograph showed their ES to be better. I keep the Federals for the 222 and the Tac now. Link to comment Share on other sites More sharing options...
