Thread: 7 Rem Mag - barrel length

Just put a new timney in yesterday. Has had some form of bedding work but have it noted to watch. Load dev went ok, .7" at 100 but if they aint touching I'm not happy The trigger may improve my groups. First round hit at 895 so she's put a smile on me dial so far That the furtherest I've shot with my own rifle, the 270 is all but a distant memory

Nice work... I've dialled mine in now but being a Tikka its taken a few trips to the range and a lot of shooting other rifles in between as I can only shoot 3 shot groups with the barrel and suppressor set up as they heat up to much and it starts walking the POI to 11o'clock - regular as clockwork beyond 3 shots. Hence the comment about heavier contour barrel in the future.

I'm also gonna try federal primers instead of the Winchester magnum primers as I've had a few click - no report misfires of late, good indentation just no boom. Have also been using IMR7828 for powder and getting really good accuracy out of this between 62.9 and 63.1 grains - bugger all difference in the groups. But Reloaders was out of these federal magnum primers when I started so I was kinda waiting to get an issue before I changed out. fortunately my issue wasn't like rambo260's in the weekend. Still have 2 and a bit packets if anyone wants them...

Will be interested to hear your results.

Can lend ya Nathan fosters book on accurizing if ya want (drop me a PM) think I'm gonna be busy over winter with reloading at the moment.

I've got a Lammington CDL in .223 and it is a absolute corker after those two things!!! although guys tell me its bust due to the bolt being on the wrong side.

Bolts definitely on the correct side.

I went through similar thoughts, now have a 26" rem mag with brake in manners stock and a suppressed 19" 284. One for open country tahr shooting etc the other for my general hunting. Ballisticaly on paper they aren't far apart but in a practical sense they are completely different the bigger setup is much nicer to shoot long range and groups very well a long way out
