shoot57 Posted February 3, 2013 Report Share Posted February 3, 2013 i have a tikka varmint in 243win and load my own 65gn v max [when i can get them] , at the moment using 70gn sierra blitz king , but i do like 55gn heads but i can no longer use these as i cannot seat them deep enough in the case. Is there any way that a rifle smith can shorten the chamber? I usually seat about 15 thou off the lands but if i try with 55gn they hardly go in the case Quote Link to comment Share on other sites More sharing options...
JonathanL Posted February 3, 2013 Report Share Posted February 3, 2013 Sounds like the throat has been eroded a bit if you were able to use them previously. The only way to rectify that issue would be to set the barrel back further and re-cut the chamber. J. Quote Link to comment Share on other sites More sharing options...
nicholiath Posted February 3, 2013 Report Share Posted February 3, 2013 I use 56 gn vmax which also are too short to seat .15 from lands so i was advised to load to standard oal 2.650 and crimp . it works for me. Quote Link to comment Share on other sites More sharing options...
kent Posted February 4, 2013 Report Share Posted February 4, 2013 Forget jump length totally. Just load them correctly into the case, you wont get near the rifling with any factory .243 win and these 55 grn rounds (or any similar) yet they still shoot extremely well in most. There really is too much talk and theory about jump and Jamb in factory guns its mostly meaningless. Quote Link to comment Share on other sites More sharing options...
