Throwback

All the boy’s were up at Wild Bill’s Sandy River camp for the annual Memorial Day "extravagunza". I brought my .41 Mag Ruger Blackhawk and my Remington Model 81 .35 Remington so that I could test a few new reloads. I had a great time shooting a plethora of great guns.
The .35 has been a recent project of mine. My goal is to find and settle upon the best loads using Lyman’s 358315, which runs about 206 grains lubed and checked. Accordingly I loaded up with available powders for velocities ranging in purpose from plinking and light game to big game hunting. I have not finished development of the hunting loads. Those will follow later as soon as I have the opportunity to test them.
I worked my way up to the following combinations while testing initial accuracy at 50 yards with 5-shot groups. A Marlin 336 RC with microgroove rifling was also used for comparison. All loads used R-P cases trimmed to 1.912 inches and primed with Winchester Large Rifle primers. OAL was 2.043 for all loads. Bullets were quenched WW, sized .358.
#1 Trail Boss 9 grains Best Group 1 3/8 ~ Worst Group 2 ¾ ~ 1,124 fps velocity, 22.8 es., 9.7 sd.
#2 Unique 9.5 grains Best Group 1 1/8 Worst Group 1 3/8 ~ 1,290 fps velocity, 24.7 es., 9.6 sd.
#3 Herco 10.4 grains Best Group 1 1/16 Worst Group 1 11/16 ~ 1,359 fps velocity, 55.4 es., 20.3 sd.
Above loads must be manually cycled. Recoil is very pleasant and only “bounces” the action.
#4 IMR 4227 22 grains 1,677 fps average ~ Poor Accuracy and Erratic Velocity
#5 2400 19 grains Best Group 1 1/8 Worst Group 2 2/3 ~ 1,719 fps velocity, 33.2 es., 14.8 sd.
#6 SR 4759 19 grains 1,725 fps average ~ Poor Accuracy and Erratic Velocity
#7 Accurate 5744 23 grains 1,726 fps average ~ Poor Accuracy and Erratic Velocity
#8 IMR 4198 24 grains Best Group 2/3 Worst Group 1 1/2 ~ 1,590 fps velocity, 56.3 es., 25.2 sd.
Above loads were pleasant to shoot and all cycled the action reliably.
#9 Win 748 32 grains Best Group 2 3/8 Worst Group 3 ¾ ~ 1,941 fps velocity, 24.2 es., 10.4 sd.
Win 748 was tried as a potential hunting load. Groups were well centered and evenly distributed but they were not tight. This load recoils very much like factory.
Load #8 was the most consistent all around and it will get a lot of use by me. I was quite surprised that loads 4, 6, & 7 were so unsatisfactory but hey - that is why we test!
Herco and 2400 would occasionally throw some flyers so my vote is for Unique, Trail Boss, and 4198 as the most useful powders tested so far. Helpfully velocities are diferent for each. The Trail Boss is plain fun and as soft shooting as you can get. Both Unique and Trailboss were especially good in the Marlin, which of course functioned normally with all loads.
Load #9 would not stabilize in the Marlin. I suspect that harder bullets sized to .359 or larger might improve things.
The Model 8/81 is an exceedingly well made rifle that could not be made for anything like reasonable money today. But for the uninitiated it is interesting to note that it kicks out of all proportion to its cartridge with factory-level loads. With loads it likes, it shoots like a dream and it will drop anything you can hunt in Maine. Lighter loads add to its versatility.
