25/35 data

bobwesley

for my t/c need loading data for unique and 2400, bullet 69gr gas ck. data seems hard to find thanks

FWAddit

You're right, very scarce info on 2400 in .25-35. You may need to work up loads from scratch. I found some recommendations on the internet for IMR 4227 and SR 4759 with similar bullets; starting loads are 7.5-8.0 grains. Since Alliant 2400 is a little faster than those two similar powders, If I were doing this, I would start with 7 grains and work up.

Don't take that as a recommendation--just information about the way I'd do it. Your choice may be different.

I couldn't find any data for it, either. There used to be loads for it in the T/C Contender brochure/load guide - but mine seems to be hiding from me.

Even my "Pet Loads" doesn't have .25-35 loads, and there are VERY few rounds that Ken Waters never reviewed! He does say that the rimless 25 Rem is the ballistic equivalent, but he lists jacketed loads only for that.

If it were mine, I'd work up to about 1500 fps in a handgun barrel or 1900 in a carbine and call that good. That's about as hard as I push cast bullets even with gas checks. I'd begin with the Unique, and whatever charge weight I topped out at would be my start weight for the 2400.

thanks, i loaded 5.4 gr unique sofar its accurate but a little weak. sounds about right to start with on the 2400, i have a little data for 4227 thanks again

O.K. Lyman Ideal handbook #40 printed in 1955. .22 Savage Hi-Power. (This is the 25-35 case necked to .22 That is all that old Arthur Savage did to come up with the Imp[:0]). #2400-12 grs, 4227-13 grs, Unique-6.5 grs, & 15 grs. 4198. This is for the 60+ or - cast H.P. bullet. Same book for 25-35 with cast 85 gr bullet. 10 grs. 2400, 10 grs. 4227, & 7 grs. unique. I shoot a lotta lead, but not in my 25-35 contender carbine. It likes 27.2 grs. 3031 & a 90 gr. Sierra HPBT. Have fun[:D] Eddie

thanks a million, was trying to work on a 90 gr deer load also, is the 90 gr load accurate say at 75 to 100 yds?

I use 5.5 grs. Unique with a 100 gr. Lyman GC in my 25/35 Contender. Makes a nice light, accurate plinking load.

My old Lyman Handbook of Cast Bullets has a number of 25/35 loads using cast bullets but nothing lighter than 85 grs.

Using 85 gr. bullets, loads using Unique run from 7.0 to 9.0 grs., loads using 2400 from 10.0 to 11.0.

They also have some loads for 100 and 110 gr. cast bullets. If this would be of any use to you I could post it as well.

Hope this is of some use to you.

yep my dad gave me that old mould, he started loading right after ww11. sorry to say he lost all his old manuals and notes. hay but thanks.

Bob, This load is super accurate in my 22" Texas Contender carbine. Velocity is 2650 average F.P.S. Coyotes out to 250 yards are a given. Due to the 8" twist, I believe it's killing power is greater due to the bullets high rpm's. I have "misted" Remington 86 grain 25-20 bullets using this rifle. By the way, these are explosive & accurate if kept below 2400 fps. BTW, I tested a lot of loads before settling on the one listed. Bought my cases & dies from the auction side also the barrel. Search Contender barrel. There are always 160+ for sale.[;)] Edquote:Originally posted by bobwesley

60 grain lead, 6.5/Unique @ 1,790 fps
86 grain lead, 7.0/Unique @ 1,660 fps
60 grain jacketed h.p., Unique 7.0 to 9.9 (1,720 to 2,160)
60 grain jacketed h.p., 2400 12.0 to 20.1 (1,870 to 2,880)

Lots of other loads for 86/87 up to 117 if your interested.

Old data though, Phil Sharpe, Complete Guide to Handloading, 1953

Doing the math we find the bullet rotates less than once per foot of travel. What "witch-craft" is at work that makes folks believe bullet rotation has anything to do with killing power. Just something to ponder - I'm not hijacking the thread.

bobwesley

thanks alot and yes the more data the better, will try them as i empty my 20 cases. or my new brass makes it to me.soon i hope. thanks

bobwesley

to elubsme, ed i tried the 90 gr bthp with 3031 in my 10" tc didnt burn all yhe powder. any suggestions?

Rocky Raab

There is already a thread about "High RPMs and killing power" in this forum.

elubsme

How was the accuracy? Maybe try a faster powder, but Hodgedon's 2009 manual lists 3031 for all bullet weights from 60 to 117 in a 10" barrel 25-35. As mentioned earlier mine is a 22" carbine. Part of the fun in reloading is the experimenting. Just don't take chances. Edquote:Originally posted by bobwesley

ed,accuracy was ok can i use a hotter primer, i have used 3031 alot in the past in other ctgs,really like it.also 4227 what do you think. the 90 gr i have does not have a crimp groove. (cannalure)
i have alot of old bullets that i use on my 257 rbts, 256win.trying to get a use from me and pappy's old stash.
