Will the brass chamber without the bullet ?

Is the brass "expanded" to much ?

MattSako · #5 04-16-2011, 06:59 PM

yeah the brass fit very well in the cylinder, it just dont go all the way in.. so i was thinking the bullet isnt seated deep enough

i found some info that i should seat em flush with a 1/16 crimp. can anyone confirm. thank you

I may be wrong but i don't think you need to be crimping that load. Did you try without the crimp ?

Yeah the same thing hapenned, the amo just didnt wanted to go all the way in .. im gonna seat it almost flush and try it again in my gun

Looking at it a little more your COL is listed at 1.180" for that round in 38 Special. No listing in 357 mag as it is a target load. Are you using 38 special brass ? If you don't have a hornady manual i could send you load data for your load.

On the Hodgdon powder site's reloading data they list the col as 1.290" for 148gr HDY LHBWC. Check their site for the entire 357 Magnum loading data.

Just to rule out other possibilities, can you easily fit a factory load? If so, suggest compare some measurements using a caliper...

I load hbwc in my 357. I seat them .050" over the top of the case. As others have said play with your expander so it will still fit in the cylinder but just. I don't use a crimp with mine. Not that I think you don't take care of you pistol but is the cylinder clean? After about 100 rounds in mine the round start to get hard to load because of pure lead and unique.
