[QUOTE="ishayajazz, post: 883713, member: 46397"] HI There! I know about this. I just got back from the range using the 55 grain ttsx out of a Savage 12 LRPV .22-250. It is a 1:9 and was beginning to show signs of stability issues at 5 degrees fahrenheit. So, I would say that the answer is a definitive no out of your 1:12. The issues associated with bullet stability are more related to length of the bullet than its over-all weight, although weight is a factor in the equation. This bullet, at .896", is long for a 55-grainer, thus requiring the high twist. FYI 35.3 grains of Hodgdon Varget with Lapua brass and CCI BR-2 makes a 1/2" group at 100 yds out of my savage with this bullet. That said, this is at or above 30 degrees. which corresponds to sterility of 1.43 or higher. At 5 degrees the stability was 1.32 and groups opened up to 1"! So… just use the berger bullets stability calculator for your future satiability calculating needs and keep the SG around 1.5 or greater and you'll be fine. [/QUOTE]
