100 grain grand slam loads for .243

[buckeye hunter]

I don't have a speer reloading manual.   Could one of you give me some of your load recommendations for this bullet using IMR 4350 and or H4895 powder with a Remington #9 1/2 large rifle primer?   Please send them by PM if you don't like to post loads.

#12 shows
imr4350 34-38 max
h 4895 not listed.
my bullet 105 speer is listed with the 100 grand slam.
my 243 will put one ragged hole at 100yds with the
105 and 41.8 H4350 yours may like H4350 also that is
H4350 38-42max
as alway work up to your loads.but mine loves that load and it loves
the H4350 with Hornady 87 hpbt also.
mine also likes Varget with the 58 Vmax by Hornady.

Speer #14 (2007) shows the following for 100gr Grand Slam with IMR 4350, using Winchester cases and Federal 210 primers:

Start 37.5gr, 2643fps, Max 41.5gr, 2880fps

H4895 is not shown.

Hogdon's web site shows the following for 100GR SPR BTSP with H4895:
Start 31.0gr, 2683fps, 44,900 CUP, Max 33.0gr, 2818fps, 50,100 CUP

And for comparison, they show the following for 100GR SPR BTSP with IMR 4350
Start 38.5gr, 2760fps, 43,000 CUP, Max 42.0gr, 2958fps, 50,100 CUP

Hope this helps!
