Home Forums Reloading Big Game Rifles 30’06 200 yard groups, Which would you hunt with?

https://www.24hourcampfire.com/ubbthreads/ubbthreads.php/galleries/14671472#Post14671472

This link has my 165 Ballistic tip, 200 yard groupings w R17 in my Nosler 30’06 rifle. Powder volumes were...
55.5gr. -2840 FPS....1.1” group (5 shots)
56gr. -2870 FPS...2.2” group (4shots)
56.5gr.-2920FPS..1.5” group (4 shots).

Looking at the 55.5 vs the 56.5gr loads, which would you choose for a hunting load. Max range is 500 yards for whitetail.

If 500 yards is potentially on the menu, even with a little less velocity, I’d go what is behind “Door #1”....55.5 grains! memtb

Definitely load #1.

You could also try 56-57gr of IMR-4350 with that bullet and see if that tightens the groups up any.

Higher velocities won't mean much if you can't hit the target.

Load #1

If nobody has mentioned it yet, Load #1 looks to be the most useful.

You need to shoot more groups. A decent load isn't going to double in size with a .5 gr increase in powder, what you're seeing isn't statistically valid. Shooting two groups doesn't tell the story.

These are 200yd groups at 500 yards it even the 2.2 is only 5.5.Still in zone of an elk. Doesn't matter all that much.A t500yards,the accuracy is going to be the shooter,but still go with be best if you have it.

What is the drop of any of them at 500 yards?

I would still be shooting at 500yards to check out any load

100 yard zero @guesstimated 2800 fps 54.5” @ 500
200 yard zero @ guesstimated 2800 fps 45.01” @ 500

Crow hunter, is correct. The smallest group (1.1" 5 shots) may turn out to be the most accurate, but with such a small sample you can't know for sure. Also, saddlesore has some good thoughts too, in the end, it really shouldn't matter much.

When fired from field positions you won't shoot a 1/2 MOA rifle a bit better than a 1 MOA rifle. Those group sizes are only relevant from a bench. And while you have enough velocity with any of them for 500 yards all else being equal speed never hurts. I'd choose #3.

Option 1. Confidence in your ammo is mentally important. A 1/2 MOA load is more than adequate for 500yards; spend your time practicing field shooting positions.

I would shoot larger groups of 10 first to see if there is any real difference in accuracy among those three loads. The data you have is inconclusive. Barring that, I'd go with the fastest load, because with the small sample size you are shooting 1.1" and 1.5" are essentially the same.

I'd re-shoot 55.5 grains and see if it was repeatable or not.

Trick questions?? 😂

Not enough groups to validate

Don’t over think this - your 55.5 gr load would be my pick. Small differences in velocity mean nothing, especially in this day of rangefinders and ballistics calculators.

That is why my main hunting rifle in 30-06 gets 200 gr Partitions for everything - it is very accurate and I know the trajectory. Oh, and that 200 gr bullet will kill everything pretty quick and not cause much meat damage.

I'm loading 56.0 grains of IMR 4350 behind 165 grain Sierra Game Kings, 100 yard groups are great and killing power on whitetails is exceptional.

Even if this rifle is one you have shot for a long time and have supreme confidence in, one group of 4 or 5 shots means nothing. You need to burn more powder before making an informed decision.

I've always found IMR 4350/58gr/any 165 to be an "accuracy load". Essentially, even other powders "in that burn rate" have also been very good from 56-59gr. "what I do", is to shoot, say #3, over again and if I think its a good one, I actually shoot it out to 500yds ( though I don't shoot unwounded game much past 350) to look at drops and groups. If its consistent, bingo. I think any of the groups show promise, and try to stay at least around 2800fps/any 165. Good luck to you pard!
