Starting to warm a little to this little 450/400. Really expected it to feel neglected once my 470 arrived, but since it needed some additional attention from JJ, decided to show the 450/400 a little attention today since I had to run out to the range to test a few rounds through my daughter’s Fieldcraft before her moose hunt. With moose season underway and many folks getting ready for late season hunts, the club was relatively busy where I couldn’t go down range to mark every shot or two, so set up two targets with small orange aiming points.

Trying to get my feet back under me shooting open, iron sights. It’s been some time since I did much rifle shooting without a scope/optic of some kind. And while I may well run an RMR or similar, trying to see what my abilities are with the factory irons. When I first shot the rifle, I had decent light and was pleased with the factory brass front sight. When I finally got to shoot my 470 late last week, it was raining and shot from the main rifle range, where all stations are covered, or in the shooting house (Where you cannot shoot offhand). I found it very difficult to pick up the front sight on a black target while under the roof and therefore shaded. So figured the cardboard and orange dots would help…proved true.

These were first shots with the factory DGX I’d taken through the gun. The two outer holes were the first two and did those kneeling off-hand, which I seem to be imparting some vertical to the gun in doing so, especially with the solids. Then followed with the next two that I shot off a bag that stacked well, and seems most consistent point of impact with other groups, although the next 4 shots I tried to adjust towards getting the rifle centered. Found success, but then after some offhand shooting the following went back to the same shifted left POI.

Here were the next two shots again off the bag rest…and was really getting happy with myself, my aging eyes and the gun.

Then came the next two rounds, again of the bag rest. First shot was super happy., quick check through field glasses and saw it hit essentially same POI as the pair before, then fired the left barrel and felt like a good shot but left guessing, did I pull it just enough to slip through the first hole, it looked ever so-slightly ovate to the bottom right, but wasn’t sure if my mind was playing tricks on me instead of considering I’d somehow pulled it entirely off the target. I don’t think I did, especially using the bag rest. Even my marginal, at best, total off hand and kneeling off shots were not far enough off to miss the target entirely…one was close though.

Here is the whole target.

Then to mix things up a bit.

Had a chance to go down range and put up another target, and switched to the factory DGS, only had 6 rounds of the DGS with me, and shot three pairs kneeling offhand, which in retrospect I wish I’d shot the final two off the beg to see if the vertical was something in my kneeling offhand position or the load itself. When I switched back to DGX, I also decided to stand up and shoot offhand, concrete on my knee and vertical groups were starting to make me grumpy. Next pair of offhand DGX were widely spaced, but vertical was gone. Still unsure if it’s me, the DGS, or some combo of both. Certainly didn’t do myself any favors in trying to ascertain which. Shot two more pairs, back to the bag rest with similar, size and POI of the first pair I shot off the bag. Rifle seems to like the DGX.

With other folks still shooting on the line, and have several rounds left, figured I’d throw a pair onto a steel plate at 100 yards. The sound and somewhat centrally placed splashes were satisfying, so sent another pair down range. Not the best group, front sight essentially covered the square plate, or at least most of it.

Still waiting, moved over to the target I’d shot with my daughter’s Fieldcraft, and couldn’t really aim at the individual targets, front bead just totally covered it and couldn’t really get a repeatable aiming point, so decided to use the white void between the bottom four targets. Squeezed off a round, checked through the glass, about fell over, hit the exact spot I was aiming for. Maybe this little 450/400 should stick around a bit. Fired the left barrel, and as folks were looking almost ready to go cold, quickly reloaded and sent two more downrange. Cleared, line went cold, went to see where the next three went and pull targets. Whelp, the next rounds were closer to each other, but not to the first hit, so think it was likely just a lucky anomaly.

First shot is the perfectly centered shot into the center of the white void between the targets, I do not know the order of the three below, so cannot say which was the left barrel, or the L/R in the second pair. Lots of room to improve, but given the size of the front bead at 100yards, wasn’t entirely upset either.

I will play around with an RMR HD or SRO on the 470 when it comes back to see how things improve. Absolutely think it will help at distances out past 60-70 yards especially. Regardless, I am warming to the petite lil’ 450/400….lol. It’s the plain, yet lovely gal on the right.

That’s great shooting and regulation with factory ammo.

Really nice shooting and groups!!! Beautiful guns!!!
 
That's great shooting, personally I'm struggling with my double rifle open sights without reading glasses!!! I fitted an RMR red dot for a recent hunt on my .500/416NE double, it allowed me to shoot well with a lot of confidence out to around 100 yards. I suggest you give it a try, it looks like your gun is well regulated and shoots well, the RMR will help with quick target acquisition and getting the rounds where they need to go.

The DGX bonded ammo shot really well in my double and I decided to hunt with it as I did not have much time for load development, it performed great for me on Australian water buffalo & camel.

Good luck with future range days and hunts.
 
Wildwillalaska, those are a beautiful pair of rifles. Thanks for sharing with us
 
Looks great. If you’re hitting a paper plate, at 100 yards, it’s plenty good enough!
 
Nice shooting the 450/400 is just a nice round, and your rifle is regulated VERY well. You will find if you put a red dot on it the groups will become more consistent and will most likely take the vertical impacts you saw outta the picture as you will have a much more consistent aiming point. I have a 1moa Mr on my 500/416 and shoot it out to 150 with confidence.

Thanks Dave. It really does shoot the factory DGX well. The barrels will need to make a trip to JJ for slots to mount the RMR, but will allow the new owner to make the decision as to if/when he does that. I shuffled a couple things around a bit towards my long term pairing/trio goals. And JJ fixed the firing pin issue on my 470, so it’s headed back to Alaska. So hopefully I’ll get out for my first real range day with it soon.
 
I'm telling you Will, my Heym 470 and 500 are going to sit in the safe or vault as the little 450-400
Heym of mine has truly gotten a warm spot in my heart. My mom shot almost everything in Africa
with her 450-400 using crappy Kynock ammo 60 years ago. My dad called it her "little double". With
good bullets like A-frames and North Forks, it's no wonder it's becoming the favorite client DR gun in Africa. Put a RMR 1 MOA on the rib and you will find it the most useful DR in Africa. JJ has a slick mount and if your guns rib isn't milled (pre-2014) he will do that for you. Give me a call or PM me and I'll Give you my loads and they will be close to where your gun is regulated with very little messing around!
 
Hello WildWill, is that 450/400 built on the Heym Light Frame? Do you have a weight for it? That would tell.

Good Afternoon,
How firm are you on your Dakota 416? I am highly interested but looking at a few different guns currently.

Best,
BJ

What is the minimum you would take.

I have a Chapuis 450-400 double that looks brand new and shoots well, never been hunted from what I can tell. I am willing to part with it as I have a 375 H&H Sodia on it's way from Dorleac & Dorleac. I am looking for $9,250 for it and if you are interested, I am happy to send you some pictures. Regards,
Steve
