7mm Intl Rimmed

[Lee Martin]

I always wanted to work with the 7mm International Rimmed. Growing up during the IHMSA heyday I remember how popular it was on steel.

We just got this one put together so I thought I'd post a picture:



I'll be using SR 4759 powder with a 162 grain Hornady Match. 18.5 grains to be exact which should give 2,000 fps from my 14" barrel.





I haven't got it to the range yet but will report back with how it shoots.

Anyone else work with this round?

I haven't worked with the round, but read a bit on it. It's an excellent round as I recall. And that's a beautiful custom Contender you've put together, Lee. As always, very impressed.

I had a Super 14" 30/30 and ran the 150 grain Nosler Ballistic Tips at around 1900 fps and they slammmmmmmmmed the steel with authority. That 162 @ 2000 should be perfection.

I was always surprised how well I shot the Contender. It was practically magic in my mind and really opened my eyes to the accuracy potential of a finely manufactured pistol. It seemed like I never missed with that Contender.

Since nobody is helping you out here Lee, I will give it a shot at the risk of being a HIGH JACKER!! My improved 7mm on the 30-30 case is Reeders 7mmGNR. I get wonderful accuracy out of it. I run the 120 grain NBT and have killed quite few hogs with it. I suspect it gets a bit more velocity than yours as the shoulder is blown quite a bit more forward. Its a killer of the first order!

[Lee Martin]

Neat rig Fermin. I've heard good things about the GNR. It definitely has more throttle than the 7mm International with its improved shoulder position. And while the International has a 38 degree step the long neck cuts capacity a bit.

Looking at load data I may be high with my velocity expections. It appears 160's go a tad over 1,900 fps from a 14" Contender. Still a hitter and the load cited above is supposed to be accurate as hell. We'll see once I get it on the bench.

Oh I bet it shoots just fine. When that 160 lands I bet it will do so with authority. I seriously doubt any fairly hit critter will know the difference between yours and mine.....

Never got into the single shot scene, but very nice Lee, Really interested to see how it shoots

, If your looking for a fun "Explosive" bullet on small game take a look at the speer TNT bullets, 115 grains. I loaded some with my 7 rem mag for future use on coyotes, Tested them on wet new pack very impressive. It be alot for a ground hog but sure be fun!

I picked up a 14 inch 7TCU barrel at the last Alabama Gun Collectors show that has been re-cut to a 7mm International Rimmed. I was beginning to believe I had a fairly expensive tent stake because I couldn't find dies listed for it anywhere. But I see hope.....where did you find dies for yours, Lee?

[Lee Martin]

I lucked into a never used set of Redding dies. I think they still offer it as a custom but they're not cheap.

Here I was thinking that I had pretty much everything that I needed.

You guys are not at all helpful.

That's a very nice Contender Lee. I was on a silhouette retro kick awhile back and had OTT make me a 15" fluted barrel in 7mm Intl Rimmed. Added a Ken Light short rib for scoped use and the Bo-Mar/Bond iron sights. I haven't gotten around to trying SR-4759 yet, but that is my favorite powder for the BR cases and many others. I'm using IMR-4895, BLC-2, W-748 and H-322, mostly with 150 grain bullets. I really like this round in a TC.

[Lee Martin]

I like that. The fluted barrel and target sights look spot on. Glad to see others working with the round.

That is a really nice looking rig. I'll bet it really shoots well too!
