Henry Repeating Arms 41 Magnum Big Boy Steel

Written by Sierra Bullets Ballistic Technician Gary Prisendorf

When Henry Repeating Arms announced the release of a 41 Magnum Big Boy Steel in January of this year, I immediately went in to a must-have-it mode.

After saving back enough money with my Ramen noodle and hotdog diet plan, I was able to get one a few weeks ago.

When I received my new rifle, I was impressed.  It has a perfect fit and finish and the wood on it is excellent.  Really what else would you expect, it’s a Henry.

To be honest I wasn’t too excited about the buckhorn rear sight, so I elected to throw a scope on top of it just to see what it was capable of.

The only scope I had laying around that wasn’t already mounted on something was a 2.8-10×44 Simmons Aetec that I had removed from another rifle that was traded off a couple of years ago.

I got the Big Boy scoped up and loaded up 30 rounds of ammo, because that’s all the brass I had on hand.

I loaded 15 rounds with the Sierra 210 grain JHC SportsMaster #8520 and another 15 rounds with the Sierra 170 grain JHC SportsMaster #8500 using Alliant 2400 powder and Remington 2 ½ primers.

At the range, I sighted in the rifle at 50 yards with both loads.  Both grouped very well clover leafing less than an inch.

At that point I figured 2 inch groups at 100 yards should be very achievable and set up to test on the 100 yard range.

Before I give you my results, I want to point out that this Henry 41 Magnum is a pleasure to shoot, it functions perfectly and the trigger though a little heavier than I like, breaks clean and crisp which was a surprise for a lever gun.

Now back to my 100 yard accuracy test.

I believe it was Colonel Townsend Whelen that once said, “Only accurate rifles are interesting.”  And I sure hope my Henry gets a little more interesting.

Honestly I was a little disappointed, the 210 grain load shot 2.778” and the 170 grainers shot 3.214”.

henry-41-magnum-big-boy-steelI am certain I can improve the accuracy by a little load development by tuning a load to the rifle.  After all, I just picked a couple of loads out and threw them down range, so there are a million things I can do to improve my preliminary results.

I really like the rifle and look forward to finding a good load for it.  It’s plenty accurate to pop a whitetail at 100 yards, but I know it can do better than that.  Shooters have good days and bad days.  My first day at the range with my new Henry Big Boy Steel definitely wasn’t a good day, but as we all know, the worst day at the range is still better than a good day at work.

    Bought one of the .41 Mags as soon as they came available. It is a perfect mate to go with my Ruger Blackhawk .41. Also recently bought a Ruger Super Blackhawk Hunter in .41 (available only in stainless steel). I have always loved the .41 as a hunting and general shooting cartridge. It is also a shame that .41 ammo is becoming rare and hard to find. Thanks for the report, I agree with the summary but, my Henry is a keeper!
