My 243 (not an M77 however) would not group the little boat tails at all. 1-1/2" was the best I could do with the 58gr and 75gr v-maxs. Soft-pointed boat tail hunting bullets of 80gr and 100gr also didn't fare very well. I was losing hope. Finally tried some 95gr SSTs because they were flat-based (friends advice). I had all the little stacked-up groups I could shoot. I didn't measure all the groups but the ones I did were in the 5/8" - 3/4" range which I was happy with.

I'm a pretty big fan of the sst bullets they have performed outstanding in the calibers I use them in ,but I havnt had a chance to load any up for my 243 yet.

The only bullet I tried which was too long was a Swift Scirroco (95 gr.?)

Another trick to try on a Ruger M77 is to open the magazine trap door and see if the mag sleeve will move just slightly with finger pressure. There needs to be some movement to ensure the action isn't being pulled down on the mag sleeve and causing some distortion of the action when it's torqued to 90 in/lbs. Both of my M77s were tight and it's not uncommon that this one little thing will correct a poor shooting rifle. Generally this will render better results than a pillar bedding job. On the bottom side of the sleeve, not the action side, Using a HAND FILE, at the contact point of the the trigger guard in back and the trap door hinge in front, remove just enough metal to get the sleeve free front and back when the action is reassembled, usually only a couple of thou/ in. More is NOT better and you may need two or three tries to get it right. Takes 15 minutes to accomplish. Worked for me on a 6mm and an '06, it may work for you.
