Propelan yang telah digunakan pada munisi dalam negeri berasal dari banyak produsen dan masing-masing memiliki karakteristik yang berbeda. Karakteristik propelan yang diamati pada penelitian ini meliputi komposisi utama, kestabilan, titik nyala, moisture content, bulk density, nilai kalori, bentuk dan ukuran granulasinya. Dalam pembangunan industri propelan di dalam negeri, diperlukan penjelasan ilmiah mengenai pengaruh karakteristik propelan terhadap balistik interior agar penelitian dan pengembangan propelan di dalam negeri dapat sesuai dengan kualitas yang diharapkan. Metode yang digunakan dalam penelitian ini adalah melalui eksperimen di laboratorium dan dilanjutkan dengan perhitungan menggunakan metode Heydenreich. Semua karakteristik propelan yang diamati cukup memenuhi spesifikasi yang diperlukan untuk munisi 5.56x45 mm dan karakteristik yang dimiliki propelan cukup memberikan pengaruh terhadap performa propelan. Kemajuan teknologi yang begitu pesat membuat propelan single base (sampel A) mampu memiliki performa seperti propelan double base (sampel B, C dan D). Kecepatan yang dihasilkan pada balistik interior sangat dipengaruhi oleh dimensi granul dari propelan meliputi bentuk dan ukuran granulasi propelan dimana kecepatan pembakaran dari propelan extruded dengan single perforated (sampel A) cukup lebih tinggi daripada propelan dengan bentuk ball (sampel B dan D) dan flattered ball (sampel C). Sampel dengan ukuran diameter lebih kecil (sampel B dan D) memiliki kecepatan pembakaran lebih cepat daripada sampel yang diameternya lebih besar (sampel C). Metode Heydenreich dapat konsisten dengan hasil eksperimen, dapat menghitung kecepatan dan balistik interior terhadap panjang laras.
Kata Kunci: Propelan, Karakteristik Propelan, Balistik Interior, Munisi Kaliber Kecil, Metode Heydenreich
