30-06 imr 4064 load development

well nevermind on the seating depth change. i cant reallynraise them much without loosing too much contact with the case mouth. at the current depth they have exactly .308 inches of bullet in contact with the case mouth.

Sure you can. One caliber in is more of a guideline than a rule. My most accurate loads in 2 different military rifles are run out to 1/2 caliber in the neck. Concern would be excessively rough handling.
 
and it looks like these bullets will reach the lands at about 3.41 inches. if i set it at 30k off the lands i would only have about 150k in contact with the mouth

idk man. i better stick to the old guild lines. otherwise i could get in over my head pretty quick and not even know it. still new at this
 
im thinking about running one of the lighter loads, if i run it at all. it would put me around 26-2700 fps according to hornady data and thats not bad for where i hunt with shots ranging from 30-150 yards mostly. its also a little tighter group and closer to point of aim as well.

Do you notice how your groups walked up and then back down. That is barrel timing. The high 49s and low 51 area peaked and then came back down. I would work that area at the peak and run seating depth test.
Noticed you adjusted poa never mind.

A 150 grain bullet at that speed has killed a lot of deer...and Nazis
 
View attachment 1135935 The Nosler guide suggests you’re a tad low on powder charge. What other powders have you tried ?
i tried 52 grains first. got a rec from a member here. figured id give it a shot. it was the worst so i did a ladder test.

i have been using blc2 with these and my best was a 1.25 inch group. i figured good enough for deer but i cant see buying more imr 4064 for this load. blc2 is much cheaper

i have a pound of stayball 6.5 on the shelf. i think ill save it for something else.

im gonna test a ladder load of imr 4895 with 150 interlocks soon and some 150 grain interlocks over 50 grains of accurate 4064. if niether of those are mind blowing ill just buy hornady whitetail from now on. it shoots 3/4 inch groups from this rifle and its cheaper than buying a bunch of components for testing.


lets get down to the nitty gritty, these sst bullets in this rifle sit .2 inches off the lands and the rifle is old and shot alot of rounds. i think im gonna move up to 165 and 180 grain bullets. they will be longer and maybe i can get closer to the lands and still habe plenty of bullet left in the mouth of the cartridge.
 
Push them out a little, and use same headstamp brass. Better yet if you do a full prep and sort by weight or same lot and short size brass fired in your rifle. If this is OF random rifle brass, probably explains your inconsistent primers and vertical stringing. Using mixed brass, your groups are about what I'd expect.


99% of these were rp. there were 2 winchester in there.
 
so it wasnt a great day of shooting. best group, measuring widest distance from center to center of the holes, was 1.31 inches for the 48 grain load. the 47 grain load measured 1.62 but 2 holes touched.


im thinking of ignoring the cannelure and seating 30k off the lands and trying some loads again. maybe from 47-48.5. what do u guys think?
What’s your goal on working up this load? If you don’t have chrono data, then if it’s a 100 yard hunting load, what’s wrong with the load at or around 48.5?
 
I personally would stick in the 48-49gr range and not bother fiddling around with seating depths. Nor would I bother crimping unless it's an auto loader.
IMR4064 is a great powder in 06 with lighter bullets, sure there are better these days, but I could always get 150 and 165 gr bullets to fly good with it. Moving up to 180gr bullets, you'll want a 4350 burn range.
Old rifle lots of rounds......when the last time the copper was completely cleaned out of it?
The primers aren't much of a concern, you may want to check the brass. I'm not much for Remington brass unless I absolutely have to use it
 
maybe it is the rifle....but i doubt it. it shot this group a couple months ago. honady whitetail box ammo 100 yards. i clean it after every session. im more apt to believe it just doesnt like these sst boat tail because after 2 work ups with 2 powders i cant get smaller than 1.25 inches.

nothing, itll work for deer. i just cant see spending $50+ for powder when $35 powder shoots about the same with the same bullet.
 
I have fired hundreds of 150 grain bullets through a 30-06 using IMR 4064 and my standard generic load was 51 grains with the base of the bullet set flush with the back of the case neck. I used this load in several rifles and it always shot good. One thing that will help anyone's reloading is to full length resize the case and then use a Sinclair neck sizing mandrel to size the neck .002 under bullet diameter. The bearing surface of a 150 grain boattail is so short that they get out of the barrel in a hurry. There is no reason to crimp bullets used in a bolt action rifle. Sierra 150 grain GameKing bullets shoot really good in my rifles with Reloader 17.

That rules the copper theory out
well the next ladder test will be with 4895 and flat base interlocks. i think thats the exact same bullet in the whitetail line. im curious to see how it does, but like i said if it doesnt i wont waste any more money chasing 150 loads when the box ammo is $1.50 a shot. Ill try longer bullets like 165s or 180s so i can get closer to the lands
 
I don’t think the rifle likes that particular powder even if you did change bullets, none of those groups really came together and showed much of a pattern.
this rifle has shot alot of bullets. its also possible its showing its age and prefers a flat base now. ron spomer was talking aboit rifles getting wore and not shooting boat tails well. idk its a little over my head. well see how it does on the next test but im thinking the 165s may do better anyway. .2 off the lands is a big jump
