Working with my remington700, scope and 308 reload for a few months. Today is the first time to get consistent result and working up with the load. Pretty happy with that.

• Rifle: Remington 700 ADL ($400 from Dicks)
• Scope: Primary ARMS 4-14X44 FFP 308/223 HUD ACSS
• Ammo: 308 reload. Lake City brass, CCI200, AMAX 168gr, Varget (42~45gr with 0.5gr incremental)
• Setting: sitting with sandbag front and rear

total 40 rounds, with 8 5rds-groups. The middle one is to set zero, then shot in the order from group 1(42gr) to group 7(45gr)

While I am happy with the result, through it is not exactly sub-moa yet, looks promising. The scope is a good one just it is not for benchrest shooting with the chevron reticle. I do have a few questions:

1. Almost sub-MOA if use the best of 4 rounds(out of 5). what should I improve from there?
2. group1(42gr) and group2(42.5gr) are very close to the center, but group 5(44gr) and group 6(44.5gr) though grouping well are to the upper-right corner. what's the reason?
3. Group7(45gr) is a bit hard to open the bolt after firing. I attached a picture of primers. Is there a pressure sign?

thx

Different load will have different rifle harmonics.
My previous savage model 10 also likes 44gr varget on 168gr Bullet.

@tsoiky, thanks for your response. I moved the post to reload section in hope of answers about the reload

Dont choose your ammo based on the scope and hitting center. Pick the ammo that gives you the best grouping. Once you settle on ammo that gives you the best groups, you can zero your scope using that ammo.

PS. your 2nd and 3rd pics dont work
