243/Retumbo/100gr

[Ksmirk]

Ok fella's first off I know that this is not the best powder for 100gr. bullets but it rocks with the 107smk's and being I have close to 10# I was wondering your thoughts about loading some 100gr BTSP Speer bullets for some deer. My 308 finally crapped out and the barrel went South and there is no way I can get it re-barreled in time so I just thought I'd load up some bullets for deer. I have a case full of the Retumbo with the 107's and really don't know if I could get enough of the Retumbo in the case for the 100gr. bullets? let me have your opinions here folks. Later,

IMO...Retumbo is a bit slow burning...even for the 107's...but if it works for you, use it.

You're probably not gonna get a good "seal" around the brass with the 100's and Retumbo...but that's just a guess because I have never tried it.

Look for soot (black stuff around the neck...maybe also on the upper 1/3 of the brass).

Yes the Retumbo is right on the edge of being too slow with the 107's! I get a little ring about 1/16" of soot on the neck the 4350 would have a clean neck but I just never could get good groups so I just deal with the little ring of soot, get out the steel wool and make it go away. I was told about some powder I belive Hogdon is making Hybrid 100V that is supposed to be great for the 100 and 107's trick I'm having is finding some around town. Thanks I pretty much figured the Retumbo would be too slow but I just needed someone to verify for me Later,

I'd agree that it's going to be too slow for anything lighter than the 105/107s. I shoot 105 Scenars with Retumbo and unless I stay close to the top, it's not consistent. For lighter bullets, I'd go to H4350.

I like Alliant Reloder 19 for 100 grain bullets in 243...it gets the best overall performance in my guns...best mix of speed and accuracy.

[Ksmirk]

Has anyone got to try any of the Hybrid 100V powder yet? the charts I have looked at is stating it to be a good powder for both the 100 and 105-107gr bullets but have yet to see any in town yet to try out. Later,

try 4831sc near or at max, I never could get 4350 to group in my Rem 700 vls.
