.243 cal, 1:9 twist, Short Barrel - What Are You Loading?

[waynewjw]

Just got into reloading, shot my first 5 rounds of .270 at the range yesterday. Success, gun didn't banana peel, no black eyes, and now it's time to tinker for the perfect load.

So, I've just purchase a Ruger M77 MkII RSI Internationl in .243 cal, with an 18.5" barrel. I tried out some 95 gr. Federals just to get the scope sighted in, but ran out of range time to do anything more. I'd like to develop two loads, one light in say a 55 gr. for varmints, and one in 95-105 gr. for deer.

Anyone out there with some experience in this calibre that can offer some accuracy advise>

I don't have a short bbl but I have great success with varget and87 g v max

Varget and H 414 or IMR 4064 all work very well in my 20" bbl 243.check your manuals.

A 1 in 9 rifling twist probably won't like 55 grain bullets. A 75 or 80 grain varmint bullet will likely be better. Mind you, there's no reason not to work up a deer load and use it for varmints. Nothing beats varmint hunting for practicing with your deer rifle.
You'll have to sight in again after you've worked up the load.
Been using 90 grain FMJ's and 105 grain SP's with IMR4350 for eons myself. Not with a short barrel though.
