I had a chance to run out to the range today (06/22/12) with my little Chapuis .375 to shoot it across the chrony. Temp was about 85 degrees.

I had asked that my gun be regulated with Kynoch ammo and then later, at the urging of some fellow AR members, I asked that they change it to Norma ammo. Well somebody didn't get the message because I have a perfect regulation target and it was indeed regulated with Kynoch ammo.

The Kynoch ammo is not "hot". I shot five rounds across the chronograph and got an average of 2344 fps with an extreme spread of only 20 fps. (R2355, L2335, R2339, L2351, R2343) The Kynoch ammo was loaded with 300 grain Woodleighs RN SN. All bullets were crimped in place.

I shot four rounds of some ammo that I had loaded. The load was a Jamison case, Federal 215 magnum primer, 72 grains of H 4350, and a 300 grain Hornady RN SN. My loads were a bit faster but not as consistent. They were running 2390 fps with and extreme spread of 47 fps (R2406, L2406, R2359, L2389).

My plan is to back my load off one grain and try crimping them in place.

What type of groups did you get?

Dave, those are nice numbers no matter what. A 300-grain .375 slug at 2350 means trouble for whatever it strikes.

Is this rifle a 375H&H flanged magnum? If so that is right in the ball park, and if the composite group is mixed with the point of aim in the middle of the composit group you have a safari maker! Look out Simba and Mbogo!

I want a 375 flanged double in the worst way! I simply have always had a warm spot in my hart for any 375H&H rifle rimless belted in bolts and single shots or flanged in doubles.

congratulations

Mac. I agree on the allure of the .375 Flanged. The first double rifle I ever held in my hands was on old off-face in .375 Flanged that was handed to me by one of the Duckworths at a sportsman's show in Portland, Oregon, about 25 years ago. I've been a goner ever since.

Yes, it is a flanged .375. Steve Hornady winced when I told him I was shooting Jamison brass so I put my hands on his shoulders and said "that's cause my friend Steve won't make me any brass." He laughed.

I hope that Steve listens to you. I will have a new Searcy .375 H&H Flanged sometime in Sept and would sure like the availability of Hornady brass too.

What's wrong with Jamieson brass ?

.

My understanding is it is pretty good stuff, but can be a little hard, a little thick and the company is out of business.

I always thought it was fine.

Hard ?
Anneal it.

Did I miss the pics of the rifle?

Antlers:

I sent some pictures to Biebs. Told him to pick out the ones he thought came out best. I am sure he will post some soon.

If we had the .375 Flanged Mag in this country, no one would be shooting 9.3X74Rs. I definitely wouldn't have been, for the past 30 years. Hell, back in the day, when 9.3 bullets were hard to get, I used to swage down .375s in a bullet press. Not sure why the 375 flanged was/is not produced more.

Nosler is suposed to have tgeir line of safari ammo out this summer including .375 flanged.

Disagree.

Their has always been a high demand for 375 Fl guns, as shown by how quickly they are generally snapped up.

Brass was available for years from Bell (both incarnations but less so in the second company) and then others started making it as well.

Brass is often available if people seriously look for it as opposed to waiting for Midway to have it on special.

I see it the other way around; no one made guns so all of us got 9.3s because they were already being made. And I am talking about over the past 30 years, when I got my first 9.3. If european makers had been making 375s, they would have been bought readily; bullets were already widely available and brass could have been. The demand followed the supply; it didn't drive it, on such low production items.

I was referring to Bill's question.

But I do agree with you that no one was making guns in that calibre.

In fact, up until the 80's, DR's is any calibre weren't exactly hot to trot in the US and 9.3 was a dead calibre until recently for the MAJORITY of shooters.

The demand was there (for 375 Fl Mag), just no one made guns and those that were already made were snapped up.

+1 The Jamison brass is great stuff, but it is expensive and hard to obtain. I hope Steve decides to make some. Butch Searcy sent me a note the other day saying CorBon is now making loaded ammo for the .375 Flanged Magnum.

I have a few hundred pieces but could always do with more so add me to the list for Hornady 375Fl brass.

BTW, I've never had any problem with Jamison brass in 600OK, 585 AHR or 375Fl.

I was referring to Bill's post as well. What I meant is that for the past many years, if you wanted a medium bore double (regardless of how many were available), it was usually imported in 9.3 caliber. Brass was so hard to get that I used to buy .444 brass stretched out to 9.3; it was crap but was all that was available; sometimes you could get RWS but that was hard to find. .375 Flanged was and is a much better choice; maybe we have a chance to influence that and change the course of history if we all order one.

I started on a 375 Flanged Magnum project about 15 years ago and there was almost nothing available. I bought the only brass I could find. That project is being finished this summer and it seems that there is 375 Flanged ammo and brass everywhere.
