The .338 Edge is up and running

[scope eye]

By not using mag primers, and burning the powder slower, you can use more powder or a faster powder, without causing a "spike" in pressure.

Interesting. Guess I'll try my regular large rifles and see how they do. Would there be less, consistency, with a regular LR primer versus a magnum? (As far as burn rate or anything) I'll be using the gun for ELR, that's why I ask. At over a mile, every little thing will matter.

[scope eye]

I have found more consistency with non mag primers, as far as shooting a mile, I am not going to pretend I know anything, I have no clue what it takes to accomplish this, I am going to to stick to what I know, which is 5 MOA bullet drop after that I have no interest, so basically 600 yards which is 1/3 of what you want to accomplish, I would not be surprised if the same approach applied but I cannot confirm that.

I noticed in Shawn Carlock's comments and documentation of load development for the .338 Edge noted a greater ES with the non-mag primer. Looks like his go to primer in their pet Edge load is the CCI 250.

[scope eye]

That is because he is launching 300gr bullets, opposed to my 160s and 185s,

"Magnum" doesn't necessarily mean hotter and varies by brand, could only be a difference in how hard the cup is. I've never run anything but CCI 250s in any of my 338/300RUMs...targets and chronograph never gave me a reason to try anything else.

[BarrelBurner]

With plans for shooting a mile plus I figured that's the most comparable for what UpslideDown might be loading.
I however am going to give the Standard primers a try with those 165gr Barnes. I am getting close to max load with the Mag primers so I will see if the standard primer give me a little more wiggle room.

[upSLIDEdown]

Yeah, I noticed that too. 300gr hybrids are what I'm planning on shooting. Guess we'll see what happens.

Same here. We stocked up on cci250 after I built my fist one, never even tried any other. No reason.

Weather wasn't great yesterday but i went to the range anyway for more load testing on the 160gr TTSX'S. I was able to hit 4016fps with 102.5grs RL17 and WLR mag primers, but that's my max load for that combo.
Next go round will be with standard rifle primers and see if that allows a few more grains of powder.

Accuracy wasn't bad, all 5 rounds were in a group right at MOA even with the Magneto Speed hanging off the end of the barrel, so it looks promising.

Too many "once a year to the range" guys out being Deer Season is in full swing for me to be comfortable enough to grab my targets, although they were more than comfortable enough with me to start heading down range without calling a cease fire, needless to say I picked up my toys and was outta there. I'll work on the 6br loads later.

Gotta love the amplified shooting muffs though, I learned from overhearing from one of "them there Experts" as he explained to his less knowledgable buddies that, that thang hanging on the end of my barrel (Magneto Speed) was to keep the barrel from jumpin' up when ya " let one fly". LMAO!!

[D.ID]

You didn't ask the experts for help?
Clearly the opportunity to talk to such a knowledgeable pro does not come about very often, Once a year sounds about right..... maybe a little optimistic, every other year perhaps.
I can't believe you missed that opportunity to get edjumicated.
Survived another run threw the gauntlet known as the public range..........It's amazing more people don't get hurt there.

[scope eye]

You made me beam with pride, with what you did with those 160s.

LOL, the 160's work and are devastating. So are the 300's.

i learned more than you might think! I learned that them that them there Burris scopes like he had were expensive, they wuz like the Cadillac of scopes and he corrected himself, no more like the Ferrari of rifle scopes!

Not to sound too much like the kid in the candy store but what the heck. I'm going to drag the Edge out in the woods this coming weekend and see about "meat testing these loads".
So I loaded up some more of these little demons and hit different local range to sight it in for them.

Well Now I'm really pumped up, turns out this rig really likes this load i mean really likes it. I don't go to this particular range normally because you aren't allowed to go and pick up your targets. I tried to take a pic thru the scope but phone wouldn't focus well enough.
Comparing today's 3 shot group with the .226 ctc previously posted in this thread it looks as it may have broken into the .1's with these 160 grainers.

You are "the man" Scope Eye, Thanks again.

[scope eye]

I have yet to see or hear of a rig that does not do well with this load, be 338 Lapua, 338 RUM, or 338 EDGE.
