Need advice for reloading a .243

Hey guys, I could use some advice on bullet/powder selection for reloading a .243. I just bought my son a Browning Mountain Ti in .243 with a 1 in 10 twist. I've read so many forums that say 100 grain bullets are OK or no an 87 grain is max for that twist. It's overwhelming!! I plan to use it to take my son (now 12) whitetail hunting. Any advice on bullet weight, powder loads? Anything will be much appreciated. Thanks in advance, Tim

An 80grn Nosler BT with 46-47grns imr4350 works well as will a 95grn Hornady SST with 46-47grns H4831sc.

I had my best luck with 37gr IMR4064, Win Primers, and 100gr Sierra Game King's. I can't get the velocity much past 2850 FPS as I have a short 22" barrel. RL22 also worked well but same scenario on the velocity. Good luck.

Re: Need advice for reloading a .243

you do not say where you are. whitetails vary from the 60 pounders here to 350 in alberta. the .243 deer bullets generally are the ones 85 grains and up . i have used the 85 sierra bthp, 95 partition, 100 partition, 100 horn, 100 grain sierra btsp. for accuracy I4064 and varget. for a little more velocity H/I4350 or re-17 . my most common load is 42.0 of I4350 and a 100.

Re: Need advice for reloading a .243

Thanks to all of you for your advice. I live in South Carolina and deer wt. can range from 70lb. does up to 200+ for bucks, but around 140-170 are average. Wanted to get some loads ready to find my sweet spot for my rifle before it gets too hot here....and deer season does start August 15th. It'll be here before you know it....thank goodness!!!!

Re: Need advice for reloading a .243

The faster the twist, typically the heavier bullet you can/may need to shoot.
for example, berger recomends the following twist rates for these bullets:

95 vld 1/9 twist
105 vld 1/8 twist
115 vld 1/7 twist

I have a 1/9.25 twist ( a little faster than the 1/10) and it loves the 95 berger vld hunting with 41.5 grains of H-4350. it is very picky with the oal, but once that was dialed in, it shoots them great. I didnt try the 105 berger,but did try some other bullets in the 100- 105 grain range and couldnt get them to shoot well.

with all of that in mind, i would say your gun will likely favor something in the 90-95 range. I am not saying this is the gospel, but if it were me, i would start in that area. actually because of th luck i have had with the berger 95 vld hunting and h-4350, if i was doing another 243, thats exactly where i would start.

good luck

"I've read so many forums that say 100 grain bullets are OK or no an 87 grain is max for that (conventional 1:10) twist."

Well, sadly, that kind of BS is a great part of 'web guru' advice. Fact is, a .243 in 1:10 twist works well for any common bullet weights from 100 down to 60 gr.; if there's an accuracy problem it's NOT because of the twist.

I've had excellant deer killing service on SC/GA deep woods deer with a .243 for years using common 100 gr. cup and core bullets loaded around 2600 fps, think I like Hornady's round nose best and any one of the 4350 powders does a good job. The accuracy and penatration has been well within need out to as much as 150 yards and the recoil is quite mild.
