    Default Mark V Synthetic 30-06

    Here is a picture of my Mark V Synthetic 30-06 that will be here Thursday. I will put a Zeiss Conquest on it when it gets here and I will post a picture. I will also use this thread to post my load development results and data. I will be using the 168gr TSX with IMR4350 and H4350, Winchester brass, 210 Fed primers. Hoping to get 2900fps plus and good accuracy.

    Dude....your obsession with Weatherby rifles in troubling. I had that same rifle some years ago chambered in 270 Win, it shot alright, but it rusted badly on a sheep hunt.

    You better burn some of that wood before the ants and termites get it.

    Nice looking rifle. Isn't it comforting to know that you have a right to keep a gun for traditional purposes?

    Flyer55 you are right about the wood but my chimney just got fix. Katrina damaged it and it is just now repaired. I will burn it this year. Yeah, a gun for traditional purposes.

    I use a special synthetic oil that a friend of my and his company developed and I wipe down my rifles with it each time I begin a hunt and the stuff really works keeping my rifles in good shape. You might be right about the obsession thing with Weahterby's.

    Here is my initial effort at the range this morning with the first 165gr bullet I tested which is the Sierra Game King HPBT using IMR4350, IMR4895 and H380. The pictures are velocities and groups which are max loads with the above mentioned powders and bullet. It is encouraging both in accuracy and velocities and I believe I will be able to tighten up my groups some more by not having to shoot through the chrony but solely focusing on my target. These groups are already good hunting groups but I think I can close them up. Still have to test the Accubond, Partition and TSX. The last target and chrony picture or on the following post.

    165gr HPBT at 100yds using IMR4350


    Average for IMR4350



    165gr HPBT at 100yds using IMR4895


    Average for IMR4895 (flash blurred out last number which is a 2)

    Default purdy groups...

    That is some fine shooting, beartooth. If it was me, I would stick with the 4350 and 165 gr Sierra and not think twice about it. But then again, I don't have the time or money to put into thorough testing. But if I did, I certainly would try it, because the more shooting, the merrier

    I went back to the range real early this morning and started shooting by 7:20am. I upped my load a half grain with the IMR4350 load and did not exceed a safe load. Here is pictures of the group which is a little over an 1 1/4", and the case which extracted very easily and the average velocity. Now I have not cleaned my barrel since I started my first shot to test loads because I want to see how long it would go before it was very evident I need to clean the bore. I will clean it now and see if this group gets back to the size of the last group I shot yesterday.

    I will clean my bore, then shoot three fouling rounds then I will shoot a five shot group with this load and that will tell me what I need to know.

    Beartooth, those are some awesome velocities for a 30.06. Do you have any secrets on how you're achieving them? Great groups also. Thanks for the posts, it's very interesting to watch the progress.

    MontanaRifleman, I believe it is a few factors such as the Mark V receiver and obviously a great chamber, IMR4350 and 24" of barrel which is giving me fantastic velocities for a 30-06 with know pressure signs or ejection problems. I have owned a lot of 06 rifles, Sako, Winchester, Remington, Savage, Kimber and Ruger and not one of them every gave me these speeds with a 165gr bullet. At these velocities I am actually getting 3296-3300ft pounds of energy at muzzle with this load. Which leaves me 2750 at 100yds, 2275 at 200yds, 1862 at 300yds and at 400yds still have 1509ft pounds of energy and that is not shabby for a 30-06

    MontanaRifleman, I thought about your request for a while and so that no one is confused or left in the dark let me explain further about my load. The first post of IMR4350 was a max load and since I was not getting pressure signs and cases were ejecting fine and group was good thought I would knock it up a notch (1/2 grain) and see how it did. So both were in my opinion max loads and they are a couple of steps above some published loads. What I meant by safe load was that it was safe in my rifle. Sorry if that confused anyone thinking I meant a published max charge. These loads I am working with are over the book max. Now for the sake of your curiosity my first posted velocity for IMR4350 was 60grs and this last post is 1/2gr more and you must use Winchester brass because this is a compressed load and Winchester brass will hold it. I would recommend that anyone reading this start a 56-57grs at the starting place and work up looking for acceptable accuracy, velocity and pressure signs especially if your rifle is not a Mark V. Please do not use the charges I have if you have not worked up to them. Even a Mark V with not a favorable chamber would show real pressure signs with this load. Now the picture of my brass is evidence that my specific rifle is fine with this load and the easy extraction is all some evidence.

    Thanks for the explanation Beartooth. I guess some loads in cetain rifles will safely exeed published max while in some other cases just the opposite. I agrre about starting safely below published max One thing good about that, besides the safety factor is it's educational watching for the signs as you go up, primer flatness, bolt stifness, etc.

    Still some real good velocities there, approaching what I am expecting out of the 300 WSM.

    I would say good luck, but I don't believe in luck, and it looks like you don't need it

    Good shooting, will be watching with interest

    I am going to the range tomorrow and will be doing a final test for the HPBT with IMR4350 shooting a five shot group and also a five shot group with H4831sc and H380. Will be adjusting seating depths on all the loads which these loads are the max for my rifle and all are over 2950fps with one being over 3000fps. What ever one is the most accurate that will be the deer load for my 30-06. Tomorrow will be an exciting day for me as I conclude this stage of my load development for my newly obtained 06. Years of loading for and hunting with the 06 in the past has really cut the experimenting time down and has given some quick and good results. Will post results some time tomorrow afternoon.

    Well, today was interesting to say the least. Is it what I would have liked? Not exactly!! Would I enter a competition with this load??? NO!!!! Was it a success in someways? Yes!! I was able to accomplish some things that really makes me happy about my Mark V Synthetic 30-06 and my deer load.

    1. By adjusting my OAL and giving my bullet just a little more jump. I was able to increase my velocities by 53fps over last time using 60grs IMR4350.

    2. My shot group is enough to hunt with even though I wish it was a tighter group. I attribute this group size and the way it turned out to the fact that it was not the first group I shot today. Also that the walking up and down the range to get a very close look at my groups because I for got my spoting scope did not help my heart rate. Then I got a phone call from work saying I need to get there earlier than I had planned and I could not take the time between shots I wanted so the barrel was on the hot side.

    3. I have decided to go ahead and use this load for my deer hunting and some time next spring I will be putting a B&C Metalist stock on my 30-06.


    4. Here are the pictures of the range, target and average velocity of those five rounds.





    Being a little over an inch will be ok in my opinion for my hunting load as I believe I will tighten it up just a bit by having more time between shoots and not getting my heart rate up.


    Average of the five shot group.

    I will being going to the range again the end of this week and I think I will be able to tighten up the five shot group buy doing the following.

    1. Not shooting through the Chrony and having that as an added issue when I try for a good group.

    2. I will take my spotting scope this time for real close up looks at my target and not have to walk up and down the range between groups keeping my heart rate low.

    3. I will let the barrel completely cool down between shots so as to see how it groups with a cold barrel for the five shots.

    4. The last time I did not trim all my case lengths the same but was close because I got in a hurry at the bench, in other words got sloppy and I have corrected that this time.

    I believe that I will be able to tighten my group up and be able to use this as a hunting load and take advantage of the great velocities my rifle is giving me. I tested some 165gr Winchester Sliver Tips and they went across the chrony on the average of 2823fps. Also shot some 300gr TSX's out of my .375Wby just to make sure the chrony was responding in a correct manner and they went across the chrony on the average of 2779fps. So my chrony is correct and the 30-06 Mark V Synthetic is getting some mighty fine and fast velocities and I think that is so cool.

    Here are some ballistics using the 165gr HPBT at an average of 3060fps: 3060fps gives 3430 pounds of energy at muzzle.

    I will be trying at the range Thursday or Friday along with my 165gr HPBT in front of IMR4350 and Fed 210primers, the 168gr TSX in front of H4350 and CCI250 primers.
