keeping your pressures back and actually watching barrel heat a bit will do more for barrel life then powder choice will usually. Look up the 204 ruger if you want to see what dropping the pressure will do for barrel life. They were able to roughly double barrel life by dropping the pressure to 58000 psi or so instead of 6400-65000 psi like normal high pressure rounds use.

If I'm out knocking off prarie rodents, I'll bring both my striker pistol in 22-250 and my 25wssm rifle. I used to bring out my striker in 243 out too, but the barrel got tired and I traded it. It keeps the barrel a lot cooler if i can alternate between the guns.

For the heavier bullets (105 and up)... Retumbo can't be beat.








these are running around 3000 fps from my Douglas 8 twist, 24 inch barrel. use magnum primer... cci250 or fed215

Re: slower burning powders used in the .243 winchester

I have a factory 700SS with a 24 in barrel that shoots great with RL22.It does not seem like that case should like such a slow powder, but I've also had good results with IMR7828. I read another post about Retumbo with heavier bullets.
The 243 is the first rifle I loaded for almost 40 years ago. It is still my favorite round for deer.

Re: slower burning powders used in the .243 winchester

I have a few pound of 7828ssc, does it make much diffrence between 7828 and it ssc brother? Im thinking 95 grain bergers.

I wish I could shoot 105+ but my factory tube only has a 9-1/8 twist.

Re: slower burning powders used in the .243 winchester

I've never used them yet, but from what I understand is that the regular and short cut powders are interchangeable.For the cost of one box of 105's it would not hurt to try them. You may find that they perform OK. Brands other than Berger , like Sierra, might work.For those a 1in9 is probably fine.

My stock Remington 700 243 loves H4831SC. I also shoot the 87gr v-max.
