Good luck with those 55grainers. I had some 50gr. TNTs also from the early 90s. I tried them in my 1 in 9 twist Savage with a 26" heavy barrel and had to keep them in the 2900-3000fpr range just to get them to hit a 100yd. target. I gave up and switched to the 50gr. VMAX. Thousands of CO and WY prarie dogs have been turned into red mist from those vmax bullets. I think the TNTs will work if you had a slower twist but not in a 1 in 8.
Just my experience
