Winchester model 70 243

Sounds like it is time for a re- barrel. Anything with a 243Win bolt face.
There are quite a few choices. --- SAWMAN

Yep, already had a discussion with my smith about it, just have too many other projects going on right now.

Real nice rifle you have. You may need to check headspace. Those model 70s don't tend to wear out of they are cared for unless you shoot tons of high speed (top + load charges) rounds.

It isn't a simple fix, but as Sawman said, it could be due for a rebarrel. Good thing is, Winchester still makes them.

Lol, I know that rifle like the back of my hand. Shot many thousands of rounds and a whole lot of critters. As the throat eroded away, I kept pulling the bullet out farther and farther to maintain the jump and good groups. I ran out of bullet, even with the heavies.

Depending on the contour you could stub the barrel.
But to me a rebarrel would be best. Around the same price,could change twist to 1:8,could change contour,switch to stainless,and have it floated. You could also have the gunsmith turn you a 11degree target crown.
All just possibilities. ---- SAWMAN

Lesson learned about shooting in that kind of heat. I just reshot the same loads and got great results. The ones I neck sized only also produced good results. I have another 243 that I may use at some point and if the full length loads shoot well in that gun I’m not going to worry about neck sizing. I think seating the bullet longer also helped a bunch

HUGE swings in temp can have a big effect on ballistics.
When I lived in Maine I would typically reload all my ammo in the summertime. Our house did not have air conditioning and it would be 75degs inside.
The problem was . . . . my 223Rem ammo was shot on a 10 above to a 10 below night while coyote hunting in Jan and Feb.There would be a pretty significant drop in velocity until I learned how to load for it. ---- SAWMAN

Hey sawman. How much if any difference have you noticed with one brand of brass to another? Say you have a pet load with hornady brass then switch to Winchester?

Glad it worked out!

The differences are substantial. I have found that some of the most consistent is Privi Partizan,Seller & Bellot,and Lapua.
I sort my brass by weight. Win,Fed,Rem,Hornady,etc,etc. And different chamberings . . . 308,243,223/5.56,etc,etc. If the weight of different brass is within 2%,I use it. No matter the headstamp.
Of course I trim to length,chamfer the mouth,deprime,square primer pocket,debur flash hole . . . then weigh on a digital scale.
The name of the game is CONSISTENCY. --- SAWMAN
