New Toys

07/31/2016

 I arrived home Saturday Night and sitting on the dining room table was a couple of boxes that I have been expecting for a while, and quite happy to finally have received.

 The first was a bag of 500 .308 caliber 175 grain bullets manufactured by Nosler ammunition company. They are part of the Nosler Custom Competition line of components and used in the company’s match grade cartridges, and sold with the normal ”Match Grade” price tag.

 Being that they are .308 diameter the number of different cartridges that can utilize these bullets is quite numerous. One of my goals is to have 10,000 put away for my retirement. Also in case that another run on ammunition, and components occur I will at lest have some items put back.

  This particular lot will be segregated for load development, and normal use.

 The second item was a 25 round box of of Nosler Brass in of course 300 RUM. These will also be put to the side for later use.

 The most important item is the reloading dies. Now I can start my load development which if I do my part, and if the rifle is mechanically capable I will be starting on my next leg of my journey for 1,500 yard hits.

 More to come shortly.

Ohio

Well the wife and I recently returned from visiting family, and friends in the kind of great state of Ohio. It would be much better if the dummies had not elected the bag of dog shit John Kasich Governor. But that is a rant for someplace else.

One of the things I wanted done was to have the muzzle of the rifle threaded for a muzzle break, and maybe at some point a silencer. 

 I had Dana Brownfield of D&D Shooting Supplies do the needed metal work. Though at this time the break has not been installed. The particular break that we decided would work best had to be ordered, and I decided to have Dana apply a light sand blasted finish to  give it a flat appearance. This will help with not spooking any game if at some point I decide to use this rifle for hunting.

 Because I now live about 900 miles from the Dana’s shop he will be shipping it to me. This should not cause any issues as the break that we chose to use has port holes milled 360 degrees around its surface, this will eliminate any timing issues.  

 Had I gone with a break that exhaust to the side, having the port lined up perfectly would be very important. Because the ports are 360 degrees there will be no correct position thus eliminating any negative pull off during recoil that could occur with a break that was timed incorrectly.

 The disadvantage to this system is that the muzzle blast will kick up dirt, and stone throwing this debris into my face.

 Don’t worry ladies nothing in this world could ever harm my most lovely appearance.

 I also purchased a set of low profile scope rings, a new set of sling swivels, a set of reloading dies, and some virgin brass for load development.

 The new mounts should go a long way in providing me with a much better cheek weld. Something I have been whining about since I started this project.

 Much more to come soon.

Just sitting waiting for the repair truck to come and fix the problem that was supposed to have been fixed last week.

Scopes and mounts.

 Not much has been going on in the 300 RUM world these last few weeks. I have been on the road only getting home on the Fourth of July weekend then doing some local, and overnight runs. 

 Arriving home last night Susan and I started preparing for our trip back to Ohio to see family and friends. But I am most excited about the fact that I will be having a muzzle break installed on the RUM. 

 Yes I have been told my priorities can sometimes be misguided.

 Now to the topic of the title, as stated earlier the cheek wield on this rifle using the S.S.A.L.T mount from SWFA is not working at all. This is affecting my ability to maintain a solid follow through hold during recoil.

 A low mount will be installed later this week after the metal work is finished. And as of this morning the rifle is at the shop waiting to be started on.

As of this morning A set of Weaver 30mm rings have been added and the metal work should be starting. Hopefuly I will be able to get some video of the mill work. 

  More shortly.

 

5 Shot’s

 Monday, June 13 I went back to Gateway with the plan of shooting several rifles, but with the heat it was not going to happen. Though it was still a very productive day.

 First I fired two rounds over the chronograph to get a velocity reading. This is where I needed a camera filming.

 The chronograph was mounted on a regular camera tripod with the shaft that the chronograph mounts to extended up about half of its total length. After firing the first round the muzzle blast caused the shaft to retract to its lowest position. Annoying but funny. The second shot had to be taken from a less than conventional position but all worked out in the end.

The readings work out to an average of 3,144 FPS.

 My next problem was that my ballistic program would not allow me to update my load information, and instead kept the old load information from a .308 Winchester load. This made it necessary to do it the old fashioned way .

 The first round hit about 8” right, and 3” low at 200 yards. This was with a cold almost clean barrel. Only the third shot after cleaning it. The first two being when I was chronographing earlier. The adjustments made and I was ready to run my last 5 rounds for this rifle for the day.

 Shooting from the prone position was fun. The recoil was definitely making itself known, but was not as harsh as it was while shooting off the bench. But with the scope mounted so high it makes good solid shots hard to achieve. I will be biting the bullet and ordering a new set of rings next week, and will have to start the process over again. 

 The process should go quickly because it has already been sighted in so the only adjustment will be the elevation.

 Until my next time at home it will be just working to pay for these expansive habits of mine.

 More to come. 

First Shot’s.

De Pain.            De Pain.

After getting everything put together and ready to go I hit the range. The first chore was to get the scope adjusted. I set up at the 25 yard position and fired a total of 3 rounds. The impact point was center target, but about 4 inches high. 

 This normally would not be an issue with most .308 Winchester loads as the impact point on the paper targets I normally use would still be in the black center of the scoring rings. Not so using  a round that is moving at about 800-900 fps faster.

 After firing 2 rounds I was not able to find the impact holes. So I moved down to the bottom sticky target dot. The point of impact was 19 inches high.Meaning the first shots were traveling over top of the target.  The reason for this was both the canted 20 MOA Weaver scope mount base, and the height of the scope rings, causing the impact point to be so high.

 This was a simple fix with the adjustment of the scope bringing the impacts into the center right portion of the target.

 Fatigue, heat, and the recoil from shooting a hard hitting caliber from the bench became an issue. So much so that after a couple of hours, and 20 rounds I was done. But not until my last two shots were all but touching, and inside of the 2 inch sticky target.

 More to come.

 

The activity for the last couple of days have been interesting.

Arriving home Tuesday night after Susan recovered me from a local McDonald’s after my failure to complete a bicycle ride from the terminal, to the apartment I was greeted by three slobbering dogs, and a dining room table of stuff.

 As I sat on the couch admiring the ammunition that was part of the pile I could feel the pain in my shoulder  already. But that is a later discussion.

 Also the scope mount and snap caps were waiting for my attention.

 The next day after taking care of a few things I started with mounting the Wyatt’s DETMAG bottom metal, and five round magazine. I was pleasantly surprised when the parts matched up without any problems. The original stock that this magazine system was mounted on required several hours of fitting before it would work right.

I tested the functionality with the snap caps and it seemed to be working well, so I started on mounting the Weaver 20 MOA scope base. 

 I cleaned the screw holes, then mounted the mount. First I applied a small drop of gun tight to the new screws then torqued them to 50 inch pounds of pressure. This is where I may have some trouble in the future as the two center screws were wanting to round out. Because of this I did not torque them to the full 50 inch pounds. At some later date the offending screws will be replaced.

 The next step was to mount the scope. 

 This was a pretty easy task because the Weaver base mount is a rail type that has become a common design feature on all types of firearms in this day and age. We are the better for it also. The scope is already mounted in a detachable mount that is designed for use on AR15 rifles using the same rail mount system.

 This presents a couple of problems, the most notable is the height of the mount. This causes a poor cheek weld or maybe I should say chin weld. This will be rectified with a more traditional set of mounts in the near future.  

   The scope is a SWFA SS 10x that I have been using for about 18 months. It has a Mil-Quad  (Mil-Dot) reticle and the adjustment knobs are calibrated in 1/10 Mil increments.

 The cost of this scope at this time depending on the model is anywhere between $300.00 and $400.00 dollars. The fact that it is a fixed 10 power allows the manufacturer to put more resources into the ruggedness and quality of the adjustment knobs, and internal parts making it possible for a new shooter to get into a scope capable of fast adjustments and corrections without having to get a bank loan.

 A U.S. Optics fixed 10x will start at around the $1,200.00 mark.

 I used a set of levels specifically designed for the task of squaring the scope reticle with the center of the bore, then tighten the mounting screws to 20 inch pounds.

 

 All of this took about two hours, having some experience doing these task before allowed me to quickly move through the needed steps, but the most important tool is just that, tools, having the correct tools, and a little bit of experience using them make the job at hand more enjoyable.

 More to come soon.
