Neat
Two 6mm cartridges. .243 with 69gr and a 6mm ARC with 90gr. Neat. Hope he does this again with some non monolithic bullets

Those are some hot loads

Comparing light bullets at max velocity to heavy bullets at max velocity out of 2 different cartridges is not a reasonable comparison

Second those rounds look so hot it not even responsible to be posting them
Third he goes through numbers so fast I couldn't even follow along

where shots are sub 300 and max point blank is the critical number then light and screaming fast is generally always the answer

I played with his numbers a bit use the same weight , same Hight over bore grabbed the mid range of load data
now think of it this way if you ran that 90gr bullet in the 243 at 3150 your minimum velocity for expansion you would be a pinch over 710yards

if you take that zero to 255yards and figure 5 inch radius or in this case 2.3 high 2.7 low you come in right at 300 yards for max point blank

now you have a bullet that had a flight path like the 243 with the 69gr bullet but your pushing max distance to 700 yards and you can have one bullet for deer , hogs , and coyotes you learn all your holds and shooting and not go back and forth. you can easily push those ranges if you have a good range estimate.

That's why the comparison was so bad. He took the heavier 6mm bullet and put it in the less powerful cartridge, then took the light 6mm bullet and put it in the more powerful cartridge and compared velocity and drop to decide a lighter bullet is better in his situation. The deck was stacked against the heavier bullet in this comparison before a round was fired

And yet now many will say light bullets are better all the time and more game will be lost and wounded because let's face it your normal gung guy is uninformed or miss informed and has very limited experience. Light bullets for many will=all light bullets and most of those are varmint bullets. And why I don't llike most Internet gun guys

Idk seemed like a neat comparison regardless. Was cool to see the lil ARC do what it did vs a larger case with a lighter bullet.

......so your saying it's bad .... because after his test .... He looks at what he wanted and decided which was best for HIS situation? I mean that sounds like it's just understanding what you want making making you pick off of your test data.

Yeah Ed is a speed demon type of guy. Just his thing for the most part lol. Has some stupid hot loads ..I know his .17 stinger which is basically the Ackley improved version of my KAK .17-5.56 is pushing 5'000 fps ..think he's blown up a .22 creed or .25 GPC too

it is a cool comparison but it would be cool to see the 6mm arc in a 55gr blitz king or a 58gr vmax

because I think he would find it very useful for HIS use which sounded like the flattest thing to 275-300 he could get

if you ran a 55 or 58 you could run 3500fps it would seem from the load data I found from the 6mm ARC for as hot as he likes it maybe 3600somthing

that would be very close to the bullet he was using in the 243win for velocity , and trajectory because speed works with light bullets to about 250-300 yards

6mm arc could be very interesting in light and fast , but that isn't the direction they typically go with it

that is where the varmint shooter and the long range shooter differ

many of your varmint guys like lightning bolts to 275-300ish
most of their shots come inside 300 and they would rather not be calculating hold over.

what wouldn't be to like a almost 243 in a AR with STANAG mags

Lol, @ 5000/FPS he’s barely getting a barrel broke in before he needs to rebarrel.

Think the smallest he's gone is this 69gr hammer.....yeah Ed is an...he's an interesting guy... Does thing very perticular . Now that I think about it he does seem to do a lot of : big case light bullet small case heavy bullet... Idk he's a intresting guy .
As far as 6mm arc he hasn't don't much with t compared to his wild cats




And an example of his....other type of experiment lol

The comparison is about light bullet at max velocity vs heavy bullets of same caliber at max velocity. But when you put the heavy bullet in a cartridge with much less power its not a true comparison. If you want to compare cartridges use the same bullet if you want to compare bullets use the same cartridge. It's not a comparison when you change two variables in same test.

You do the test using a 6 ppc and put the light bullets in it and and the heavy bullets in the 243 and the heavies would win in every measurable category.
