Guys,

Just acquired a Schultz and Larsen 7x61 Sharp&Hart and was wondering if anybody had some load info for me.I used 63gr of H4350 and 140 sierra game kings pretty good luck.It's a 1 in 12 twist so I think I should stay under 160 grains? Any help would be appreciated.


thanks, Adam

P O Ackley lists that 63 grain load that you are using with the 145 grain bullet for a velocity of 3187. He also lists a load of 66 grains of 4831 for a velocity of 3128. I would guess that would be H4831.

Adam,

Very nice rifle and a very nice cartridge to go with it.

I have a resource which has over 300 loads for the 7x61.

Instead of posting them all here why don't you PM me and I can send them to your email.

Beautiful rifle, great cartridge!!!

Uses a very similar belted magnum cartridge case much like the .264 Win. Mag, 7mm Remington Mag., .308 Norma Mag., .338 Win. Mag., .358 Norma Mag. and .458 Win. Mag., the 7x61 S&H cartridge appears to have a double-radius shoulder much like the 7mm Weatherby cartridge.

Generally, rifles chambered for the 7mm S&H cartridge are free-bored like the rifles chambered for the Weatherby cartridges. I believe your Shultz and Larsen is free-bored, but to be sure... check it out.

Full 7mm Sharpe & Hart maximum loads REQUIRE a free-bored rifle to be safe. Reduce all listed 7x61 S&H loads by at least 5% if the rifle lacks a free-bored barrel.

My old reloading manual (circa 1970) shows a maximum load of IMR4350 (64.0 grains, a compressed load) behind a 139 grain Hornady Spire Point bullet sparked by Remington 9 primers in Norma cartridge cases yielded a muzzle velocity of 3257 fps out of their test rifle, a Shultz & Larsen 65DL w/ a 24" barrel which had a 1:10 twist.

My reloading manual shows loads for the 120, 139, 150, 165 & 175 grain jacketed bullets. If you can't find any other source of loads, PM me indicating what weight bullets you intend to use and I'll send you this old reloading information I have, but remember... these loads use the components circa 1970... and current components may or may not yield the same pressures/velocities. smile


Strength & Honor...

Ron T.

Good post Ron.

It reminded me to look back at my old reloading manuals and the 7x61 is listed in both my 1967 Hornady and 1967 Lyman manuals.

To the OP, just PM me and I can get you more info than you could possibly use.

Aren't there two cases that fit the rifle with different internal dimensions because of Mr. Hart's over engineering of the original cartridge?

I think that makes a difference in the amount of UMPH you want to give your handloads, too...

SWEET RIFLE!

I'm turning green here...

You are absolutely right efw. In about 1963 Norma reduced case wall thickness by .005" and thinned the web .020" thereby increasing case capacity 5 grains or so.
The outside dimensions remained constant.
Unless you have a supply of pre 1963 brass, all 7x61 brass will be the new design.
Ken Waters reports that the new cases are still very strong and durable.

Thanks on the great info,but could you please explain free bore and how I would check it. I assume it's something to do with bullet jump to the lands or something with the belt. I'm loading these to fit in the magazine well, because that's what matters...Right? I do a fair amount of reloading but this is my first belted cartridge.

nsaqam thanks for all the info, I just hope it will be enough to get me started! shocked

again thanks,

Adam
