Loading for my BRC 32-20 and 25-35 choked barrels

So the 32-20 barrel is on the 44 1/2 now and is ready for load testing pending the arrival of a new firing pin. I have 200 rounds loaded for the 32-20 and 100 rounds for the 25-35. 100 of the 32-20 rounds have gas checked bullets (Accurate 31-125NG) and 100 are plain base (Accurate 31-125M). The BRC choked 32-20 barrel is a 16 twist so I am trying slightly heavier than normal 32-20 bullets. Also as an experiment I am trying SR primers for the GC bullet loads and SP primers for the PB loads. The loads are for the most part close brackets of the best looking loads I was able to shoot before I turned the action over to my smith for fitting the 25-35 barrel (and adding the scope mounts to both barrels). Powders being tested are 4759, AA5, 4227, Reloader 7, 1680 and 5744 in the SR/GC loads and AA5, 2400, 4227, 4759 and 5744 in the SP/PB loads. As for the 25-35, these will be the first tests with lead bullets. 70 of the 25-35 rounds are gas checked (Lyman 257325 115 grains lubed) and the rest are with a MOS plain base straight bullet.  Powders on trial are H108, 5744 4198, Unique, 4227 and, from a member's suggestion and because I have a lot of it, 800-X. Winners: to be announced.

Sounds like an interesting experiment.

What is the twist of the .25-35 barrel?

It is a 10 twist.

That's a lot of numbers mister.  Be careful.

Westerner, especially since he might be a FOP.

Definitely an OP but not so much F these days;-) It is a trick to keep track of so many bulls on a target when the loads being tested can vary so much in where they land. Also the chrony will be in use and have to keep track of those numbers also. I like to get to the range early to get the range officer's vest so that I don't get a cease fire in the middle of a string. Hey, it's all fun!

Chuck used to post a target with the blank side out and load it up with targ dots. I've seen him put hundreds of shots on one piece of paper. I always considered that practicing. 

Now days I do most of my load developement on targets in matches. I've become a tightwad in my OA. All out of Fs here as well, lol.

Maybe I should do that. I have a roll of "construction" paper from Lowe's that is the width of the height of our target frames and I just staple it on and cut it to frame width. I have target dots I can stick on and use for aiming points. Use a lot less staples that way. Just have to maintain a sheet of paper on a clipboard to note who goes where.

I went to the range yesterday. It wasn't the best day but it was above freezing and the wind was only about 12 mph or so coming from my left shoulder and twitching about 45 degrees back. But, I was anxious to get the shooting going;-) So anxious, in fact, that I failed to notice, until I was cleaning the rifle afterwards and lifted the tang sight (for which I had made a nifty leather cover) off the comb, that I had removed the top tang screw to touch up the blue and not replaced it. Ergo, the stock was held only by the lower tang screw into the pistol grip. So I set up the chrony and fired off the 200 (almost) rounds at 100 yards with some interesting results. First I shot the loads that had gas checked bullets and small rifle primers. The star was AA5. The SDs for the 3 loads were 8, 5, and 6. No other loads I fired had single digit SDs (including the AA5 loads with small pistol primers). Next go round I will try to tweak the best AA5 load plus or minus .2 grain. I will also do a little more testing with 1680. Now, the plain base small pistol primer loads were not as exciting and the next go round with them will be with 2400 and 5744. I have a lot of AA5 so I'm happy with that. I'm also refining my bench rest technique as I go and I feel better about that and of course I will have the stock firmly attached..

Oneatatime,
Ive had excellent results with the 31-125M breech seated in my 18 twist 32/40 Stevens Tip-up. Im pretty sure it started life as another cartridge with that twist. On a hunch, I designed the Accurate 31-156C and 31-156CB(bevel). Both are tapered from .314 at the two base bands to a .308 nose. Results were excellent as the accompanying targets show. The 156CB target shows that I pan lubed with ASL and then sized in a .313 die..go figure! The green dots are 3/4 dia.

So a 32-20 will shoot well at 100 yds. Have dies,brass and lyman's 311316 which is a gas checked bullet and some 32-20 jacketed bullets. But no 32-20 to shoot. Going to check out the BRC website and see what twists they have for the 32-20. Have a BSA 22rf thick walled 12/15 which I am seriously thinking getting either relined with a TJ's liner but faster twist or rebarreled. Will following your 32-20 post with interest. Frank

SBoomer, I may have to try that 125 in my 32-40. I don't really want to try a heavier bullet in my 32-20 at this point. OldMan, BRC only makes the 16 twist for the 32-20 barrels but that is faster than the old standard 20 twist. Joe, I did use the contractor's paper (I think that is what Lowe's calls it instead of construction paper) with 1 inch stick on aiming points (I found a bunch of them in the bottom of my large range box that I had forgotten about). I was able to put 12 points on the paper but could have had more since all the shots were clustered tight around the aiming points. I want to try some H108 next time as I have a lot of it and it is what I use in my 25-20 SS. I haven't found anyone who is using it (or WC820 or even AA9) in 32-20 so I will have to maybe start with a ladder test.

Oneatatime, Thanks for the heads up regarding the 1x16 twist from BRC barrels. Local newspaper used to advertise that they had left over rolls when they printed newspapers. Usually just about $5 for a good sized roll. What I have left will probably last until they shovel the dirt over me. Check your local papers as they may have some left. Funny story, as you can guess,setting up the concrete floor for a printing press is no easy thing. Massive weights,vibration and stability and alignment all have to be taken into consideration. So floors are usually cast of a dense, high strength concrete and none of this 4" thick sidewalk stuff. In this case over 2" thick with rebar. Contractor shows up and starts with the jackhammer. After about a half hour he's wondering why nothing is happening. Site engineer shows up and tells the guy the specs they used when the original concrete was poured. And your jackhammer ain't gonna do it. Gets one of these cranes with the wrecking ball. Up goes the ball about 75' and free spool down. Whump just a little dent. This goes on all day with little progress. Guy had no idea what he was bidding on. So they call another contractor who used to bust up airport runways for a living. He starts up and concrete is being busted up like no one;s business. Took him 3 weeks to break it up into chunks, then about two weeks to load the chuncks into 40' dumpsters. Nothing left but grassy fields. The second guy had all the heavy equipment and a crew who knew what to do with it. Frank

For my first Pistol Cartridge Cowboy Silhouette match my load will be my 125 grain plain base bullets over 7.5 grains of 2400 with small pistol primers. I'm still working with the AA5 with the gas checked bullets and small rifle primers. I did run some 10 shot strings comparing CCI BR4 primers with Federal Small Rifle Match primers and the results were: average velocity BR4 1326 fps SD 21, FSR 1307 fps SD 7.4. Best group (and a very good one) was with the BR4s. So primers do make a difference but SD? Also will be doing more testing with the H108 in the vicinity of 7 grains with the BR4s.

If you can find it . Try some HS-6 . After trying many different powders in my Uberti 1885 32-20, I found this to work best in my rifle. 5.2 gr. with 115 gr bullet.
