Bill... this may be too much but... If there is a sudden need for 14.7" barrels with WC brand muzzle devices, how nice it would be if WC welded and pinned the muzzle device on and installed the gas block. I know it would cost extra but likely much less than sending it to a gunsmith to have the same thing done. Just a thought.

We've spent quite a bit of time and I've done a LOT of accuracy and terminal performance testing of the new Lehigh Defense 115gr ME (Maximum Expansion) bullet specifically designed for the 300 HAM'R. We learned in order to optimize the terminal performance we had to have a design specific to 1-12/1-13 twist barrels and another one for 1-15 twist barrels due to the rotational speed of the bullet in flight.

SKU #s are:
01-308-115-SP12 (1-12/1-13 twist)
01-308-115-SP15 (1-15 twist)
Price will probably be the same as the current 125gr Control Chaos and I estimate availability in mid March.


Here's a photo of the performance of the final design.

At Lehigh Defense we've finalized the design of what I believe to be the deadliest bullet available for the HAM'R. I performs the same from point blank out to 250yds+ and does TREMENDOUS internal damage while still producing deep penetration. It always sheds 4 pedals weighing approx 11gr each that radiate out more than a Controlled Chaos with a 79-80gr base that has slight expansion to .330"-.340" with jagged edges. As you can see it performs pretty dramatic on hogs!

100yd groups from a 16" 1-15 Ranger barrel

SKU # is 17-308-125-XC $51.50 retail per box of 50, will be available late February

Big Sam, load data will be the same as the 125gr CC, I'm getting best accuracy with 26.2gr A1680 for 2450-2460fps from a 16"

Bill...how does the new Lehigh bullet do out of 1/13 twist barrel?

Performance is even more dramatic

How about the accuracy?

Bill,

I'm sure it has been asked and answered somewhere on here already, but I was unable to find it. Could you please tell me how many grains of CFE BLK you are loading in the 130 GN Speer Hot COR factory rounds? They shoot very well in my rifle and figured it would save me from having to work up the load or pull apart a factory round to measure the powder. If I wasn't an hour drive to the range it wouldn't be a big deal but it very time consuming to work up and dial in the load if I can just duplicate what I already shoot.

Thanks!

For what it is worth......
I've noticed that once you get a really good load that has the accuracy you are looking for you need to make note of its velocity. Then if you change lots of powder you want to find the load that matches that velocity.

The velocity is a result of the pressure as is the accuracy. It takes very little effort to match velocity from one lot of powder to the next IF YOU ARE USING THE SAME BULLET AND THE SAME BARREL. When I began playing with the 300 HAM'R, and the Speer 130 gr HC, that bullet gave me good results on game, but accuracy was only fair. In my playing I dropped the load down by just 0.3 grains and the results was highly noticeable. If I change powder lots I run a simple test to match velocity to the old load and I get the same accuracy results.


Not every group will match this one ( a hair over 1/2") but they will be MOA. The nice part of these results is that I now have a stash of the 130 HC (these bullets are rather inexpensive) loaded up and set aside, I can go on and play a bit with the new Lehigh Defense bullets Mr. Wilson is bringing out. When you spend hours in a deer stand waiting for the big one to step out of the brush, you want the best bullet you can get not the cheapest!


As a pat on the back to the guys working in the barrel department at Wilson Combat, I get the same results from one barrel to the next. The velocity will change depending on barrel length but the accuracy stays about the same. Those guys are consistent and their work is remarkable!
I don't want to hurt anyone's feelings, but I can't help but to laugh when I see a thread on the forum where someone is trying to find the "best" cheap barrel. That is the same as asking, "How little do I have to pay to be disappointed?"

You're welcome sir. Going from one lot to the next of the same powder really isn't that hard. (If it was I would be lost!)
I wish they would come up with a good way to measure the pressures of various loads, but at least the velocity is a halfway decent method of matching the pressure from one lot to the next. The only time I drop the load several grains and slowly work my way back up is when I'm dealing with a sensitive powder like H110 or 296. The combination of CFE-BLK and the 300 HAM'R has always been somewhat safe to work with.
At least the prices for a good chronograph have dropped over the years.
Just remember, this is a method of working with lot variations of the SAME powder. Just because I can match velocities of the same powder doesn't mean it is safe to try and match the velocity of two different powders. 2500 fps of CFE-BLK with a 130 HC may be a safe load, but trying to get 2500 fps with a different powder may be a dangerous overload with another powder type. Another common mistake is believing that a load with one bullet is safe for another bullet of the same weight. Just look at the number of 125 grain 30 caliber bullets are on the market. Each one is a bit different and the pressure each will generate can very greatly.

Thanks for the info. I guess I will load some ladders starting at 27.5 and work up to 28 and see where these guns like it.

I am guessing that most folks, like me, have gotten jammed up with shortcuts. My suggestions are to load more ammo. Shoot 4 sets of 5 round groups instead of one or two. Shoot longer. Shoot more rounds at each sitting. There is a great deal to be learned by simply shooting more in a day. And, as usual, document everything you do. I have often left the range with one impression but the documents told a greater truth after getting home and reviewing the day's results. Take pics of each group shot with each target. Let us know how it goes.

I have a question for those shooting a 13 inch barrel. I was curious what kind of velocities were seen with 115 to 130 grain bullets. Handloads or factory ammo? How was accuracy? Thanks
