[QUOTE="300rum, post: 873961, member: 6231"] Hi Dan, well, your grup is opening up because the barell heat (with sporter barels after 3-4 rounds the group will start opening up), or using temp sensitive powder. Switch to Extreme hogdon powder (H1000, Retumbo, 4895, 4831) and your groups will be rugged hole. Using 168gr is ok up to 700yrd on elk or 1100 yrd on deer, but using the 180 VLD Berger Match will do a better job on elk, moose closed to 1k. Get a 1-8twist barell (to be ready fr 195gr VLD from Berger) or using Matrix 190gr VLD's 26inch is to short for a LR rifle, and if you replace it go on 28-30in (min 28in) to achieve extra speed. matrix bullets - 190gr VLD for 7mm [url=http://www.matrixballistics.com/.284-Caliber-rifle-bullets.html].284 Caliber Bullets Custom Built for Accuracy | Matrix Ballistics[/url] For muzzle brake i have on my 7RM this model on sporter barell and i swear to good is like shooting a 223 caliber. ( I can spot all my hits, and the scope stays on target all the time.) [url=http://www.grizzlygunworks.com/D1_Rifle_Muzzle_Brake.php]D1 Rifle Muzzle Brake[/url] Choose a Benchmark barell with sendero profile and the accuracy will be outstading. I own RockCrick on my edge - only down size is ... to heavy contour Stainless - all the way - specially if you are hunting or shooting in rain or snow (no rust) Set your timney trigger as light you can (3lb is to heavy to achieve tight groups) make sure you do a full bedding on the stock (even if comes with aluminum inserts) [/QUOTE]
