This excerpt is from the book I'm translating:
Затем настала очередь 85-миллиметровой танковой пушки Д5-Т. Ее мощность составляла 300 т.м., она имела длину ствола 52 калибра и начальную скорость бронебойного снаряда массой 9,2 кг — 800 м/с и была первой отечественной серийной танковой пушкой, оборудованной системой электроспуска, по своим характеристикам ни в чем не уступавшей немецким. По дульной энергии Д5-Т превосходила 75-мм пушку KwK 42 (205 т.м.) и незначительно уступала 88-мм пушке.KwK/36 (368 т.м.).
"т.м." may be a typo for "т·м." This is from the Wikipedia article on the KV-85 Soviet heavy tank:
Дульная энергия орудия Д-5Т в 300 т·м превосходила аналогичный показатель пушки «Пантеры» KwK 42 (205 т·м) и не сильно уступала пушке «Тигра» KwK 36 (368 т·м).
Мощность пушки equivalent to дульная энергия and measured in terms of "т·м"? But I can't imagine what the units are. Muzzle energy is usually measured in terms of foot-pounds.

tpm or t*m (tonnes per meter)
Hi James,
Energy (and work) is measured in Joules, which is N*m (Newton per meter).
As these units are small for artillery gun, instead of Newtons they use tonnes, having in mind that a tonne is not a unit of weight here, but a unit of force (F=mg).
So, this should have been "тм" or т"dot"м, but a mid-height dot is not a general symbol). So, someone who was not quite understanding, made his/her own corrections and it became "т.м" - > "т.м." which was a "human factor" ))

Discussion
As for the difference "т.м" vs "т·м", there are some notes in national standard ГОСТ 8.417-81 ГСИ. Единицы физических величин
8.8 Буквенные обозначения единиц, входящих в произведение, отделяют точками на средней линии как знаками умножения. Не допускается использовать для этой цели символ "х".
В машинописных текстах допускается точку не поднимать.
http://docs.cntd.ru/document/1200031406
I think that the phrase "допускается точку не поднимать" means that one can use "." instead of "·" (for typewritten texts). Actually, I think someone just didn't bother to use Alt-codes to enter the correct symbols, that's why "т.м." appeared. Perhaps the author does not know the following requirement of the same ГОСТ 8.417:
8.2 Буквенные обозначения единиц печатают прямым шрифтом. В обозначениях единиц точку как знак сокращения не ставят.
1 ton-force per meter = 1000 kgf·m, that's why I posted the link to Wikipedia.
