I need help with a 125 gr. CB load in 30 Carbine with Win 296

[Sendaichoro]

I have a been looking for load data for a 125-130 gr gc CB in my 30 Carbine. I have good luck with Winchester 296 and 110 gr RN bullets. I have a large keg of Win 296 and would like to use it (if appropriate) with these heavier bullets, but I have not been able to find any load data or even a place to start working up a load. Any suggestions? Thanks!

I loaded a lot of cast bullets of 130 gr weight in a 30 carbine Using H110 which has a similar burning rate to 296 I would try 14 gr and work upwards if necessary

Thanks NickSS. I have noted the similarity between H110 and Win 296 as well. I was thinking that I would start working the load up from 12.5 to 13 grains. As long as the action cycles and the bullet clears the barrel, any reason with Win 296 that I shouldn't start lower? Also, I seem to remember a warning about light loads with Win 296 and a hard crimp. Does that ring any bells. Any precautions I need to take specific to Win 296? Thanks again for your help!

I'd be careful with crimping the 30 Carbine case for use in an M1 Carbine as it headspaces on the case mouth. I've never used 296 with cast in the carbine but have used it for years with the Hornady 110 grain FMJ carbine bullet. Don't see any reason it wouldn't work with cast.

Cheers,

I use 13.5 gr H110 with the 311359 (120 gr) at 1870 fps for years in several M1 Carbines. Try 12, 12.5, 13 and 13.5 gr of 296 as they a similar powders.

Yes .crimping the 30 carbine is a pain! I had some problems after crimping them. I tried NOT crimping and found some time the bullets pulled out a bit on loading.Never all the way out of the case though. I had to be carefull when opening the action with a loaded round in the chamber.

Jhalcott,

Not crimping the boolits shouldn't cause any problems when unloading the firearm. The more likely cluprit is that the boolit is engaged in the lands which holds it there when extracting the case.

I have extracted brass and powder before and left the boolit behind. It makes a mess!

When 296 first came out there was a lot of flap about loading it down causing SEEs. I wouldn't let the pressures get very light! I would hazard a guess as to not more than 10% below max.

My loads in .30 Carbine have all used H110, it is a little less space consuming, a little faster burning than 296, and probably much more forgiving at lower pressures.. And it will probably give higher velocities.

As I under stand it, the .30 Carbine headspaces on the mouth. It is critical therefore to trim cases quite closely to your rifle's chamber (just a little shorter than the longest csae the action will close on - a couple of thou.) This makes crimping them a risky business!
