My rifle has a very long throat , got some tsx's to try and my max OAL to feed in the magazine is still .74 off the lands .
that will set the mouth/top of the brass at the second pressure relief cut on the bullet.

Is that okay ?

will it seal/crimp there?

will it affect the bullets performance

:confused:
 
Work up a load with the bullet seated that far out and see if the accuracy is something you can live with, chances are it will be. Next, see if the rounds cycle reliably through your rifle. There is no safety issue with seating the bullet to the second groove from the base. I prefer to crimp all my hunting loads, and that might be a good idea in your case, as there is so little of the bullet shank in the case neck. Nothing like unloading a round only to find the bullet stayed in the throat and you have powder spilt all though your trigger group and magazine. If the combination proves unacceptable, try a heavier bullet, TSXs gain wait by lengthening the shank rather than the ogive.
 
thanks boomer
its in the second one from the tip not base of the bullet . Got a email from barnes they say its fine crimped there.
your right with the bullets being longer , its better with the grandslams & partions , I quess I could try the 175's too

This should not be a problem. Even if you had a single shot target rifle where you could touch the lands, we recommend at least .030-.070” jump for best accuracy. Unlike “squishy” lead core bullets that often need to be close, the all copper bullets like the jump. .070” is a great place to start. IF you need to adjust in or out to fine tune the groups, that is fine also. As far as the grooves on the bullet: forget that they are even there. Where ever they end up is fine. Thank you and let me know if you have any specific questions.

Did U forget a zero - .74 is almost 3/4" ???
Barnes reply assumes you mean .074" I believe. Details matter if communication is to be meaningful - especially since this measurement is the main point at issue.
