Re: What should I expect from my rifle?
If your getting 1/2 average moa groups at 100 yards, the next step for you to do is to step back to at least 300 yards and see what the load does at longer ranges.
No one here can tell you if your load will or won't shoot at longer range. Only your rifle can do this.
More then likely, it will shoot fine but everything must be tested at the longest range you plan to use your rifle at and it is even better to test farther then you plan to shoot.
Range is the greatest judge of a good or bad load. You can take two loads at 100 yards, one that shoots into 1/2" groups and one that shoots into 9/16" groups. At that range these look basically the same.
Those same two loads at 500 yards may print 1.5" and 2.5". Longer range makes it much easier to tell which loads stack up and which ones do not.
To be honest, the grouping is a good start but it all depends on yor bullet if you plan to hunt past 500 yards.
In the 7mm family there are B.Tips from 120 to 150 gr. I would only use the 140 and 150 gr for hunting at long range and for true long range shooting, I would much prefer the higher B.C. of the newer 160 gr Accubond over any of the lighter bullets.
At long range, high velocity means very little compared to high B.C. which will cut your judgement in wind errors a bit less critical.
What I am saying is you have a slightly larger margin of error judging the wind with a high B.C. bullet compared to a lower B.C. bullet.
