Mark V Synthetic 30-06

[bullet]

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.

I went to the the range this 4th of July and it was a celebration for sure with my Mark V 30-06. I had good results and bad results.

First the bad news was the 168gr TSX was not accurate using the COAL I chose along with the CCI 250 mag primer I decided to use with H4350. The smallest group was 2" but the velocities were there using H4350 59grs gave 2943fps, 60grs gave 2994fps and 61grs gave 3020fps. I had no flatten primers with the last load and no bolt marks on the face of the brass and the cases ejected easily. I will change seating depth and primers as I use IMR4350 as well as H4350 and will see what happens.

Now the 165gr GK HPBT was just awesome with a five shot group. Here are the pictures of my target showing the first three shots, then four shots and then five shots. This will be my deer load at without question. This load averages 3060fps for five rounds. COAL was 3.179" using IMR4350, Winchester brass, Fed 210 primers. All rounds were full sized because I am developing hunting rounds and want them to feed into the chamber with ease. Group size before subtracting the bore was 1.017" and minus .308" bore was .709". As you can see I had a flier on the third round then got to shooting good again.

3 shots

4 shots

5 shots

Thanks Scott, it does shoot good. It was my pleasure to give a running account of the development of this deer load. :grin:

I went to the range this morning to try a different powder using IMR4350 instead of H4350, changed to 210 Fed primers instead of CCI250 and changed the seating depth for the 168gr TSX. Accuracy greatly improved from 2" to 3/4" and velocities improved also to 3033fps. Here are pictures of the group and the average velocity.

Well considering it is a Synthetic which are not free-floated and not a B&C Metalist Stock on my Weatherby, I am happy with what I am getting. Next spring since I will have to wait around two years to get a Nosler Custom in 30-06, I will put a new B&C Metalist stock and free-float the barrel and that will close things up some

Well bullet, even in factory dress it looks like you have a pretty good starting point. Good groups, consistency, and speed.

I bought a box of 165 ABs mostly to see what they would do, but also to have an -06 load that would complement the .270's 130 load. Had not done much with them yet but after seeing this I may have to pursue further.

Good shooting.

Hey, that is cool, do it and lets see what yours does. I am going in the morning to fire a 6 shot group of the 168gr TSX to check the consistency of this round and also to try the 165gr AccuBond and Partition as I make my final choices concerning a deer load and bigger game load.

 

[bullet]

Well, it is time to end my load development with my Mark V Synthetic 30-06. I was able today to establish that the AccuBond was not what I want but the Sierra Game King HPBT, the Barnes 168gr TSX and the Nosler 165gr Partition did well.



Here is a summary of the load work for the Weatherby Mark V Synthetic 30-06 with Zeiss 4.5-14x44mm Conquest

The Weatherby Mark V Synthetic did exceed my expectations in Accuracy (especially in light of the fact that it had a tupper ware type stock) also the Zeiss Conquest did help out. The Mark V receiver and excellent Krieger Criterion Barrel allowed for above average velocities for the 30-06 cartridge using IMR4350. The following are the loads that I will be using for deer and large game. I will uses these loads until next spring when I will have a B&C Metalist Stock on the 30-06 and this will tighten up even the acceptable hunting accuracy that I have already obtained with this rifle and loads.


The Sierra 165gr Game King HPBT preformed the best in accuracy and velocity.

1,017" minus bore is .709" this is a five shot group averaging 3060fps

The Barnes 168gr TSX was second in accuracy and second in velocity.
1.083" minus bore is .775" this was a three shot group averaging 3033fps

The Nosler 165gr Partition was third in accuracy and third in velocity.
1.096" minus bore is .788" this was a three shot group averaging 3005fps

I think this is great accuracy considering the velocities I was able to achieve and these will be very good hunting loads for deer, black bear, Russian bore, antelope, elk, caribou, moose and plains game in Tanzania Africa.

Bullet, don't you just hate that "one out" stuff.

AAAAAAAAAAAAG...

 

[bullet]

Yes!!!!

:shock: :roll:

The B&C Metalist stock and free-floating the barrel will solve that puppy :idea: :lol: 8) :wink:

 

[bullet]

The Synthetic stock is my problem. Although it was quite phenomenal for a tuper-ware stocked Mark V to shoot three different types of 165gr bullets, from three different manufactures, and all be under and inch at 3,000fps plus with a 30-06 cartridge. I know that the groups could all have been a 1/2" or under with the proper stock and free-floated barrel. Although most would just be happy with what I have obtained I know it can be better. So it will be an imperative to put a B&C Metalist stock on this puppy. I can make this hunting season with it I think but for sure this coming winter I am going to have to have some work on this rifle. This is to good a receiver and barrel to get these velocities and this accuracy with a plastic stock not to do something about it.

As good as it's shooting, why not just free float it and bed it and see if you don't really like it before restocking it? Would be a lot cheaper and not take much time at all. My 30-06 shot under an inch without doing anything to it the first time to the range. I bedded it and it shot 1/2" five shot groups only the second trip to the range. Either way, you should be in great shape for the fall and the nice thing is you have time to tweak it and practice with it before it's time to get serious.

I am not really sure that a plastic stock can really be bedded. If it can and some one has tried it and it worked, I would like to know how they did it? What bedding material could eve stick to a plastic type stock like the Synthetic???????

http://www.varminthunters.com/tech/bedding.html

I have used marine tex to bed my dad's adl 30-06 in plastic synthetic stock. Believe it or not, it will shoot the 150 rem core-lokt ammo in 1/4" groups at 100 yds. (no need reloading with results like that). With some exceptions to the instructions on that website, I would roughen up the areas to be bedded after inletting for the bedding for a better stick and also, clear shoe pollish called "neutral" will work great for release agent and is cheap. Apply it liberally! You can also use Johnson's paste wax. Acetone works real good for removing any bedding compound that gets where you don't want it. The instructions say wait 24-48 hours for it to harden. I found using a hair drier will cut the time in half. Also I snug up the action screws and then back out and then snug up again after 6-8 hours for a stress free bedding job, which is what you want. You basically want the action to sit tight to the stock with the action screws as a guide more less. Most bedding compounds are an epoxy which will bond well to the plastic, but some run more than others. I have had good luck with Accruglass gel, miles gilbert, and marine tex.

 

[YoteSmoker]

Definetly make sure you use lots of release agent on every bit of the action screws. Personally, I use q-tips to make sure i pack the threads and every part thouroughly. Cotton swabs work great for the larger areas including the barrel. I also tape the front bottom and front side of the recoil lug and about 6 inches of barrel. Thouroughly, apply release agent to everything. I have never had a problem with an action sticking, and do not ever want to experience that!

 

[Antelope_Sniper]

That's good advice Yotesmoker.
Some 30-60 grit sandpaper works well for ruffing it up.
And like he said, use plenty of release agent!!

 

[old #7]

A dremel tool is a must have for bedding work. I use a small tool to create little angled cavities for the bedding to "lock" into.
I apply a light coat of Tetra gun grease to the threads of the action screws and threads in the action.
I worry about the release agent coming off while tightening the screws.
I agree with the other guys, why but a new stock when the gun shoots so well.

Thanks for the advice, instructions and encouragement. I am not sure I could do a good job bedding, have to think about all of this. It does shoot good but not as good as my customs do which are all under 1/2" shooters. Now I will admit for hunting purposes my Synthetic is more than accurate enough and it sure is a hot rod for a 30-06. Like I said, I need to take some time to think about all of this. I really do appreciate the impute, it was kind of you guys to take the time to do so. Thanks :grin:
