it might be tempting to think of 350 legend as just an up-sized 357 Magnum
that's set up for an AR like this CMMG resolute, and that is not the case. get it?
case? anyway here is 357 Magnum today we're going to be running the exact same
projectiles and the exact same powder so we're doing the Speer this is the deep
curl 158 grain projectile right here it's a huge hollow point and I expected at no
matter what speed it hits this is going to make quite a mess we're gonna be
using this same projectile in 350 legend as well and we're using Hodgdon H110
powder now right off the bat you're gonna see that these two cases are not
the same length yeah they're kind of the same diameter but we have a good bit
more case capacity with this guy bigger than that though you have to keep in
mind that we're running at higher pressures with the 350 Legend so we're
going to get quite a bit more velocity out of there
and we're gonna be able to get quite a bit more distance we're gonna see what
these do at some of their more practical ranges let's find out what the
difference is in ballistics gel
all right here's 357 Magnum hit one came in a bit on the left side and it
ended up going out and hitting the bag round two is much better placement and
you can see that the wound track that we have here is pretty decent it kind of
looks like those 223 without as much expansion this is looking like maybe
three quarters of an inch at max but it opens up very quickly and it has what
looks to be like a 10 inch long wound Channel so very nice and then it kind of
settles down and makes a great big mess and stops out here this is sixteen
inches so that's probably about 20 inches then it comes to rest right there
that's 357 Magnum same projectile same powder let's go see what we can do a 350
legend
you
the first thing I need to show you is the entry wound that these deep curls
make check this out all these others are just little pin pricks they're little
holes in the gel except where these deep curls hit it's like a flying cookie
cutter it punches a big round hole to begin with so if you are looking for a
trail with your game you're gonna get one probably on the the entry as
well as the exit our 25-yard hit with 357 Magnum opens probably about an inch
and a half in and creates a fairly long kind of wide channel through here this
probably maxes out at about 3/4 of an inch so it's not gigantic but it does
still continue to cut pretty well right around here that's about 10 inches and
then it really starts to settle down here at about oh 13 inches or so and
then cruises through here until it makes this big kind of blobby mess you can see
the projectile waiting inside it has the petals curled back this has expanded
quite dramatically even at these lower speeds our 100-yard hit is a little
difficult to see because I accidentally fired a Winchester XP over the top of it
but it's almost the same sort of channel you have this great big hole to begin
with you can see that this extra large cut that's from that kind of cookie
cutter shape and then it opens up very dramatically very quickly right behind
this wound channel cuts through here and it continues it's like it's right here
behind my finger and this one finally starts to settle down a little bit at
about the 10 inch mark and it just keeps plowing through until it finally stops
at 18 inches right here and you can see that this is just a jumble of lead and
copper this has all kinds of wicked little cutting pieces this is going to
perform very well at 200 yards the deep curl performs much like it did back at
100 so this does open up rather quickly flares out to about one inch wide at the
max 3/4 to 1 inch wide and keeps cutting for a good long way back through
you can kind of see it hanging out behind this other hit that we had but
it finally starts to settle down a little bit here at about the 12 inch
mark after that it continues to cut a pretty good channel back through here
and it ends up coming to rest at a much deeper distance than it did with the 100
and you can see that the pedals are pulled back a whole lot so we did have a
very dramatic expansion it didn't get quite as wide this time but it did peel
those petals back and we have some chunks breaking off the projectile ended up
at about 24 inches but you can see that it had actually gone forward and then
bounced back so we're looking at about 26 inches of penetration this is the 158
grain deep curl that I loaded up for 357 Magnum and you can see that it has
curled nicely it is big all the way across the only reason that it's kind of
dented on this side is that it was clipped by another projectile on the way
through that was one of those Winchester deer season XP s this is coming out to
have a width of over a half inch so we're looking at five point zero six six
right here at its maximum width yeah about zero six six yeah
big this is looking just picture-perfect let's see how much weight we were able
to retain after hitting the gel alright it was originally a 158 grain projectile it
is now 157.4 so yeah we may have clipped off a little bit when it was
nailed by that other projectile but yeah it's looking good here's what's left of
our 100-yard 350 legend projectile and it it's certainly wide it did mushroom out
very well but it's a you can see that I did peel chunks off let's put those
little chunks in there but let's see how wide this got okay it looks like a
maximum width right here of 0.62 to 8 yeah about 0.6 to 8
huge retained weight of all the chunks that I pulled out is one 29.1 and this
did leave little chunks of copper all the way back through its track this is
definitely going to cut things up very well good performance the 200-yard deep
curl certainly has deeply curled it's like it has a train it has a long skirt
going on yeah this has peeled back a whole lot but it has managed to stay
together and that's pretty cool this did have one little chunk that peeled off
and it might have a couple more back in its wound track let's see how wide this
got we're looking at point four four five on that axis yeah point four four
two right there so this did not get quite as wide as the the 25-yard 357
Magnum hit it looks like this does want to go just a little bit slower than how
he got it going with 350 legend now let's see how wide this got back here on
the skirt okay so we're up past a half inch on this this is gonna continue to
cut a very nasty wound alright let's see what kind of retain weight we have one
forty-one point one so yeah we did lose a little bit back there but still a lot
of projectile left not too shabby this Speer deep curl is another one that
was fired at 200 yards you can see that it has peeled back just about the same
and this is one that actually made a full pass through of those 32 inches of
ballistics gel let's see how much weight we have retained one forty two point
four so very consistent with the other one as far as accuracy goes at 100 yards
we are looking at three point three seven inches all the way around now that
may not sound all that great but remember that this is a cartridge that's
not really designed for precision this has all the precision that I really need
for some of these closer up off hand attempts plus I think that I can tune this
in a little bit I was doing some tests this is my own load of course and I saw
some results that were a little bit different on my
I'm gonna try those out next time I think that this recipe is just a little
bit off we'll see if we can tweak that as far as speeds go we're looking at an
average of 2,300 3 feet per second with a standard deviation of velocity of 20
1.02 so it's just kind of it's okay overall
we're gonna see some better options over here but yeah we'll continue to tune
that in my final takeaway on the Speer deep curl is that this is a
high-performance projectile and I do recommend it but some of these medium
speeds like around the 1163 that we were getting from 357 Magnum seems to be a
good performer it yeah it it kind of stretches out really nicely gets a nice
big cutting surface and it does get some some pretty nasty petals cutting through
there as well so yeah good one if you are loading up for 350 Legend this may
work in your bolt-action rifle it kind of depends on your magazine system you
might want to try some of these out but in general if you have an AR no it's not
going to work it's just too wide up front this is gonna slam into the front
