FYI, check your factory ammo

[mtank]

Nothing to "blame". They have their test barrels and he has his rifle. Not unusual for a rifle to be over or under the published data on factory ammo. It is just a fact that he will not got the same results as the factory published.

Do you blame the manufacturer of your vehicle when you do not get the same gas mileage that was on the window sticker when you bought it?

You don't think they could say his chronograph is bad? I said equipment not rifle, I've never used a chronograph so I'm not sure what the norm for muzzle velocity fluctuations is. I would think with today's technology that 400 ft/s discrepancy would not be acceptable.

And I'd be out that many bullets, charges of powder, and the all-important primers. And my BIGGEST issue is I'd have had to have taken those several hours of careful workup and repeated the process in what would likely not have duplicated my original data, since the volume would have increased significantly, so I'd have had to have done it a THIRD time.

I get 1 day off every 2 to 3 weeks, and in that day, I have to get haircuts, oil changes (I drive like 1000 miles a week), Dr appointments, vet appointments, honey-dos, etc. I have 1 day to go back to the range before hunting season opens (and then I have 1 day to hunt this month), so whatever I do has to be complete and final on that day. I drive between 45 minutes and 90 minutes to a range, depending on which is available at the time. My choice may seem irrational to some, but unfortunately, it's the best I can do. And if I'd have done it the correct way, I wouldn't have gotten to post this lovely thread so folks could take time out of their busy day and tell me what an idiot I am. It's real important to me to know I'm an idiot. I need to know others see it, too.

If it matters at all, I'll tell you what you already know: YOU ARE ABSOLUTELY CORRECT!!

You still have to fireform it and now you've wasted all this time with Remington when you have no intention on using their product in the end since you are going to handload.

Il semblerait également important de leur dire que votre carabine possède un canon de 8" !

Je plaisante. Ce message est une preuve supplémentaire et une raison de recharger. Comme d'autres l'ont dit, il est courant de voir des gens dans les champs de tir publics et de camper avec un mélange de munitions de différentes marques/types/âges... certaines personnes ne comprennent tout simplement pas.

Merci pour l'avertissement.

We all do things differently and probably for good reason.

Agreed!

I'm not criticizing the use of factory ammo for break in. I just never gave that a thought.

I, too, do not usually use factory ammunition to do barrel break-ins. I won a 6.5 CM TC Compass for $20 in a 2018 raffle. I slapped on the scope and purchased a couple of factory ammunition, 125g Winchester Deer Season XP (different lot #s for a reason) boxes for sight-in and barrel break-in. For all my off-the-shelf choices, Winchester is my choice of brass and was $10 cheaper than the rest.

(Lot # 40N71 - 4-shot group at 200Y).

(Lot # 44NC82 - 3-shot group at 200Y).

As you can see, lot #s can make a difference. So, I went back and purchased all they had on the shelf. Since then, I have harvested 2-3 deer under 300Y every year, not counting friends that have used my rifle.

This week, my first-time hunter troop harvested a WT buck and doe using 150g Winchester Deer Season XP out of a Savage. He was getting a .5 MOA group at 200Y.

I just shot my first 3 rounds of factory ammo in 30 years. I am helping diagnose an accuracy issue for a friend's brand new 7 PRC. 175gr bullets advertised at 3000fps... 24" bbl average 2730fps.

Now he's even more disappointed

But it met my expectation exactly.

That seems to be the norm for the 7 prc. Well with the Hornady anyways .

Mine was almost exactly as advertised in 7 PRC. It's probably an older box from when they were first introduced, though.

We'll find out about the Remingtons soon enough.
