Speed test results Matrix 380 & Bulldog 400

[Troubleshooter]

Speed test results on youtube: matrix 380 and Bulldog 400


1. Bulldog 400. Real speed = 387 fps (18 inch bolt / 350 grain)

2. Matrix 380. Real speed = 365 (18 inch bolt / 350 grain)

You also see: if you are buying a bulldog 400 comparing with a other bow (using 400 grain / 20 inch), you learn that the bulldog actually is shooting about 360. In fact it should be called: the new matrix bulldog 360.

FOr the record, I own 2x380 and 1 x 400BD. I'm not sure what your point is? If you shoot that same 20" 400 gr bolt out of a 380 you will get 360 ish....so then you will rename the 380 the 360???? My BD get 396-398 fps with the 20" 350grn arrow, with my hunting weights it gets 367-369.

I don't want to make a point. It is just some information about speed in combination with different weights and lenghts. Maybe some people like to see this comparison.

But about the different names: that's not a bad result for your 380!
(The Matrix 380 used on youtube should be named Matrix 340 than.)

Why I say this:
Personally, i find this confusing for buyers who are looking for a bow with a certain speed and other brands use a 20 inch and 400 grain. They can say they made 400 fps from a recurve, but actually this is a bit fake.
(I know, if you're reading close enough - you can see that Excalibur use 350 grain arrows for the test.)

Next to this, i find the 'real' speeds of these recurve bows really great and this is nothing to shame about. Therefore, i see no reason for using another speed in the name of the bow.

Something different:
I just saw there is another new bulldog 380!
Does that mean the old matrix 380 is getting replaced because the old matrix 380 had many problems? (like the replacement of the Matrix 405?)

I'm not out to give you a hard time, I'm just making some comments.
Maybe it's the camera view but it sure looks like you're crowding that chronograph.
In your video, I hear that your 380 is running 3/4" braceheight. If you are shooting with 3/4" between the string and bumper, you might want to lower the braceheight to get better speeds.
One thing for sure, different limbs will give you different speeds.

The new 380 BD is the same old 380 with a BUll Pup stock, that's it. As for confusing, it's only confusing if you make it so. Who cares what other brands do. Excalibur puts out it's factory speed based on 350gr arrow and most perform at that speed give or take a few fps. Of course if you up weight it slows down the speed - this is true with any make of xbow.

He is telling the truth
I just got a mess of the new 380 Bulldogs in
They shoot real world speed high 360s with a 350
My 400 shoots 380s with a 350

I talked to Jeff who is the us sales rep I brought this up he said as far as he knew they shoot the advertised speeds

I said they don't Jeff said he would check but I have not herd back

I love the new bows but I think they should be named what they actually shoot

i agree, my bulldog 400 is shooting same speed as the matrix 380

I chronograhed my bulldog at 367-368 consistently with a total arrow/tip weight of 400.3 gr

I tested my BD400 verses my M380. I had the same string on each, actually used the same limbs on each, had my BD string exactly 2" from end of riser as Peter suggested, and string slightly touching DrS bumpers on M380. So, same limbs, same string, same arrow : results - BD was 5'/sec faster with 352 and 397g arrows. Strings, limbs, brace height all can greatly affect actual speeds. With 352g arrow @ 5' in front of Xbow 352 was exactly 380 and 385 for 380 & 400 respectively. I used my "104" spare, blemished limbs.
So, I think the design difference is 5'/sec.

I doubt design difference is 5'/sec ,, To backup as such a person needs to test shoot several different 380 and Bull 400. Even with that a baseline needs to be establish to figure out the variants between each bolt and crossbow ,, temperature and other variables ..Plus the chronograph itself would have variables that need to be figured also ..

also forgot to mention my deck was lubed and serving freshly waxed to minimize friction on string

oops

No, it is not the same Matrix 380 with a new stock

The Bulldog riser is swept way back compared to the true Matrix riser. The power stroke was even increased with the BD...I suppose in an effort to get back the power/speed. But reducing the limb stress just takes away horsepower.??? right?

I still think Bill T got it right with the Matrix line...The 330 will last forever, the 355 is bullet proof and the 380 is a Dragster Dragsters are more about immediate performance, not engine life!!..And loaded with "TopFuel" the 405 taught us that the limit had been reached.

Just can't improve on profection And I don't mind changing engines occasionally to have the "Baddest bow you can buy!

I debated on whether to respond or not. But did you read what I wrote?
Facts: limbs have different strengths - a variable, strings weigh different weights - another variable, brace height differences - another variable, limbs may give different speeds at different temperatures - another variable, arrows may weigh slightly different weights - another variable , different chronographs may read slightly different - another variable, different distances to chronograph and sun or lighting differences will affect speed read outs - another variable. All these come into play if various M380s and BD400s are used. Such derived information would be dubious at best.
However, if the same set of limbs, same string, same arrows, recommended brace heights , same chronograph and distance to it, same temperature etc, were used then what is compared is the design performance difference between the BD400 and the original, unmodified M380 with no variables.
This is what I did. And what I found was a 5'/sec advantage for the BD400. I know of no more scientific, objective method that would be as accurate as this.

Second subject on this matter. Limbs vary significantly in strength. I have 4 sets of Matrix limbs. My weakest came on my BD400. Strongest are my blemished limbs, next strongest are my M405 limbs, followed by the M380 limbs. When on my M405, there is a difference of 9'/sec between my blemished limbs and my BD400 limbs (all else kept equal). The limbs we get are a matter of chance. For this reason plus others stated, I don't think comparing various M380s and BD400s would give very accurate results. This would be especially true if the original strings on the 3-4 year old M380s would be used while the current BD400 strings were used. There is a significant weight difference.
It's just not all that simple. I tried to take out all those variables. That's why I stick with my 5'/sec.
