Cant use the 6mm data in 243.
Just axeing a question...The 243 case will hold any load that is listed in the reloading charts for the 6mm data loading charts.I shoot 81 grains of powder in my 243 every day..The actions ARE the same.But like people are saying,the 6mmRem chamber is bigger, it will have lower pressure..That is what puzzles me ...But I guess it`s true.No arguement there..Just like a 30-06 has a lower chamber pressure than a .308
Regardless, which powder is it? There are a few powders that will go to the 51 grain area in 243, but those same powders load in the 54 grain max range in 6mm. Superform is one of them. Because of the similarity in case size, there will be significant overlap in the load data, but it's a really good bet to say that every 6mm Max load will be severe overpressure loads if crammed into a 243 case.Sorry,morcey2..I meant to say 51 grains..Not 81..Sorry.
That's almost 2 grains above the max load I can find anywhere for any weight bullet for the 6mm with a standard primer. It's over 3 grains above the max for 243, again with any bullet I can find and a standard primer.Win780..I also use the Mag. primers
Yes you can..............Cant use the 6mm data in 243.
I realize the 6mm is more powerful.but is it as accurate?Or more so?..I only shoot at paper.
Put that 50.0 gr. Compressed, in the 243 for me. Photos please.Yes you can..............

Thats just being ridiculous, I`m just saying you can use 47 grs. of H1000 in the 6mm Rem. & the .243 Win. safely.............Put that 50.0 gr. Compressed, in the 243 for me. Photos please.

i am pretty sure the op was asking if he can use the reloading data for the 6mm remington with the .243. Considering the 6mm starts out with a higher minimum and ends up with a higher maximum, the answer is no!!!
Do they have loads that overlap? Yes...but why would the op look at the loading data for the 6mm remington in order to find an overlapping load for a .243?
use the loading data for the cartridge you intend to shoot!!!
why would we confuse the op by saying anything else?
I use a Lyman`s book ``Lyman Reloading Handbook,46th Edition``,,70grain bullet-Win785 52grains....I`ve been using this since 1963..The 6mmRem.=52grains Win 785.
Why would the OP be reloading without a Reloading Handbook ?.................This right here is the reason I don`t usually answer reloading questions, and I am done with this one !..............I am pretty sure the OP was asking if he can use the reloading data for the 6mm Remington with the .243.
