speer load data needed

[lonewolf5348]

I have a early speer reloading manual from the early 70's and it seems not to have a listing for 105 speer SP in 243 cal. using IMR 4064
any one have a newer edition that may have a powder charge using IMR 4064 and the 105 Gr. speer Hot Core bullet

speer #12 100/105gr sp, imr4064 30.0gr 2414 muz. vel. - 34.0gr 2650 muz.vel. hope this helps.

My 1964 Speer manual list a min. load for 105gr. sp of 32gr. to a max. load of 36gr.

I went with 36.5 to day shot excellent funny thing I tried them with IMR 4350 and no matter what charge I used they seem to tumble or Keyhole on paper.
I tried them the other day just to get the new scope on paper and to my surprise using IMR 4064 they did not KeyHole WHY I don't know any one would like to add to the subject?

That bullet should not tumble or keyhole in the .243 unless you have a slow twist barrel. What is the twist?

1 in 10 H@R Handi

Who knows why a Handi-rifle does what it does.  I had (past tense) a new Handi chambered in 22/250Rem that  shot a 50 grain Rem powr-lokt bullet and 35.6 grains of H-4895 real well and without any pressure issue at all and the next time I shot this load, which was a cooler day, it locked up tighter than a jar of pickles.  I started over with load developement and the d&^% thing would get sticky with loads at starting weights.  I got rid of that thing and never looked back.

My H&R 22 Hornet keyholes the 55gr loaded with anythng.
