Nice rifle, John.

I've mentioned before that I had a Valmet 512 with three sets of barrels: 12/12, 12/.222, and .30-06/.30-06. I used it a lot and had a great deal of satisfaction from it.

I swapped out the single trigger for a double trigger assembly and was quite happy with that.

I've got three other barrel sets as mentioned before on the forums. Still need some final fitting.

12g/.223
12g/7x65R
.30-06/.30-06

I'm thinking the .30-06 might be able to be converted to .30 Super Rimmed. Just for fun.

I also acquired a twin trigger set, but also need to have it fitted.

I want to get a Trijicon RMR sight and get it fitted to one of the Valmet bridge mounts, so it can be put on and removed as one wants. Might work well with the 7x65R barrel and shotgun.

How is your Trijicon RMR sight going?

John - what is the manner of it's regulation of the 2 rifle barrels - do the barrels converge into a single group, or do they remain parallel, or does the bottom barrel rise to meet the top barrel, but not quite until extended range?

I'd think with some forethought, one might develope ammo that would give long range shooting from one barrel, say an automatic 350 yard zero, while normal shootin, as say a 100 to 200 yard zero from the other.

Yes if the calibre and load allows, there is no reason why one barrel (the top perhaps) or both barrels can not shoot at decent ranges.

Depending on the load and calibre. The 9.3x74R is no "magnum" especially the load I am using which is a 286 gr Woodleigh Protected Point at 2,170 fps in the 9.3mm. I could try a faster load but that was superbly accurate in my rifle.

Maybe the .30-06 barrels when fitted will show what they are capable of. As the barrels can be self-regulated, I can try lighter bullets in it, not the usual heavy round nose bullets usually used in DRs.

Tikka 512SD with U/O 9.3x74R barrels and a set of 12 gauge barrels with exchangeable chokes.

Nightforce scope 1-4 1/2 x illuminated scope.










A 1x scope is great for quick shooting in brush or at close range with both eyes open.

Same action as on my trap gun, a Savage 333T - back in the 1970's- made by Valmet. Valmet's combo guns were out then as well. Always wanted one - seemed a terrific action & excellent top lockup idea.

What is the largest calibre you have or seen made well for them?

The largest I believe I have heard of, is a .375/444 or something like that.

Thanks.

Largest cartridge, OR largest caliber? I'm always confused when someone ask me that question, because many seem to refer to "calibers" when they mean cartridges.

I designed a line of "rimmed" cartridges, then having them chambered in the Valmets 412's as "custom guns/bbls.,

left to right: .416, .375, .338 and the 30-06 for comparison


I built two 416's as "experimentals" one had problems and i never built another. I did build quite a few 375's in combo's and DR's, and they worked out very well. I also built a couple 338's and still have one around here in a combo...

There were others, but those are the most powerful...

The cartridge i liked best, is the "improved" chambering i came up with for the 9.3x74R. You can see it compared to the factory 9.3x74R in this pict.,



You can fire factory loads in the chamber, then reload the "improved brass" for a bit more power, as after fireforming it to the larger chamber, the case will then hold a bit more powder.

I did all of this for my own purpose, long ago, and do NO work for anyone else, or even play with these cartridges any longer. I've moved on to different things, but i still enjoy shooting them...

Ballistically how did the improved 9.3x74R compare to the original?

Thanks.

John, the photos of you with the game are great.

Just one question ...Why did you lay the rifle upside the animal, and don't you think you should see an orthodontist about those teeth of yours?

---

Ummm ........ ?

Have you been experimenting with the Nitro Express cocktails?

I had one of the Valmet 412s a few years ago with a set of 375 Winchester barrels. The barrels had a 1 in 12 twist. I re-chambered them to 375JDJ (444/375) regulated it and soft soldered it so it wouldn't change. The rifle was a real shooter and played hell on the New Mexico mule deer population! I wish I still had that rifle.

I like the look of those improved x74's.

John,do you like the NF scope ?.
If you had your time again would you buy another ?.

I see you had a Leupold 1-4 or 1.5-5 on it in the NT.

Someone asked me that in another thread. I haven't developed an opinion yet as I haven't used it for long enough yet.

These 30 mm scopes are too heavy IMO for a nice lightly balanced double, but on a 'Valmet' that doesn't matter. But the Zeiss. S&B and Swarovski scopes one sees on most DRs are all the same, 30 mm and heavy. Especially illuminated ones. The Nightforce is probably not as heavy as many of them. I really wish GOOD scopes in 2 1/2x, 3x and 4x were available again, especially for DRs and big bore bolts. One does not need a large variable.

I prefer a different sort of reticle to those available, but on a double for closer range shooting it should work well. I do like the 1x scope setting. Allows both eyes to be open for very quick target acquisition. Also if used on one of the combination barrels might be fine to use with a shotgun.

Given the above, I would consider another without doubt, but really would prefer a German no. 4 type reticle perhaps with the lighted circle and a dot.
