First of all I am new to this site and looks like a nice site and I signed up last night.
I am from mid Michigan.
My boy got a 243 and 20GA.combo and I also got her a 7.62x39 for Christmas.
Then I read all the bad post after I found this site last night.
WELL HERE IS THE BAD NEWS I FOUND ON THE 243 .have not messed with the 7.62 yet.
I shot this this morning and yep all over the Target! I used some 70 gr Speer TNT loads to test.
So I checked some things out!
#1 I took a new factory Winchester/100gr and pulled the bullet from the new case.
#2 Then I set the bullet just in the case mouth, then put it in the gun and closed the action, then took case and bullet back out.
#3Then I got a big surprise,the bullet was just in the case.
#4 I double checked and double checked to be sure before I made a false post here.
#5 my boys gun has a lot of free bore,you could not even get close to the rifling with a 70 gr tnt bullet as the bullet would be right out of the case.
#6 this is the specs on my boys 243 chamber.this is with a new Winchester case and 100 gr bullet.
bullet seated out to touch the rifling is 2.506"
bullet just touches the case mouth at 2.676"
this leaves .170" of the bullet in the case to touch the rifling.by no means not enough to hold a bullet.
you have .258 jump to the rifling. 1/4 inch.
Remington factory 80 gr I also tested is a .281 jump to the rifling.
I used a dial caliper and stoney point tools to measure these.
SORRY ABOUT THE BAD NEWS.
this very well could be apart of why nobody can hit the broad side of a barn with the 243.
I will try to contact Rossi with this info and see what they say about the junk they sell.
