Re: SMK flaw
This is a problem I am very familiar with ,I have a 338 L.M.Imp. that was built for shooting 1500 yards and beyond and was throated for the 300gr SMK . let me go over the positives and negatives of this awesome bullet.
I have weighed probably 2000 of these bullets and have NOT been able to cull even 1 for this reason (positive). the meplats (tip of the bullets) do have a bit of a problem ,but it varies quite a bit from lot to lot.so for this reason dont waste your time ( as I have ) and buy box's of fifty ,buy a 500 box (stock #9300t).
I have given you the GOOD the BAD and now the UGLY ,the meplats are not the biggest problem with the 300gr SMK the BIG problem is bearing surface lenght. right about now you are thinking "I've got to go to the hacienda and relieve myself" .
The tips (meplats) can be uniformed with a TUBB meplat uniforming tool (or the 99cent version shamelessly promoted on this forum). but the biggest varience with this bullet is bearing surface lenght. not something as easy to measure as you would think,you can try 2 stony point Ogive bushings on a dial caliper and come close but to get a true reading you have to get a bearing surface comparator.
Buy a box of 500 and segragate into 3or 4 bearing surface lengths then just turn off the high side of the meplat (dont uniform meplat all the way flat or it will decreacse B.C.more than you would think).
hope I did not ruin your day let me know if you need more info.
