Looks as if I will soon have 245496 Bullet mold to shoot in my two .243 Winchester rifles,. In have been using the RCBS 95 SP-GC for many years. This is a Loverin style bullet and has a reputation for excellent accuracy. Has anyone tried it in their .243 Win and can you share your results?

It works pretty well in my Circa 1980 Thumb Safety Ruger 77 V But I mostly shoot light target loads However I remember some where there is an article call "Cast Bullets for the sixes" The author I Believe found a most accurate load with this bullet and 2400 powder with the bullet seated really deep in the case....he mentioned it broke all the cast bullet rules but was his choice for varmints.... I tried it and he was right!
I will see if I can didg it up for you!

I have been told that Unique is a better powder to use than RL7 for the .243 Win with the bullet.

2400 hits right in the middle of the two.

but my guess is whomever was using RL-7 might have been trying for 2+K.
sometimes it's easy, sometimes it ain't.

I have used both ; If you find each powders sweet spot you can make them work!
Hey I actually shoot NOE's 246-105 vey accurately with small amounts of American Select at 900 fps!

Lyman's old cast bullet manual states that cast loads over 1,750 FPS just won't be accurate. Using the RCBS 95 SP-GC I stay at 1,600 FPS.

Both RCBS 243-95-SP and Lyman #245496 have shot well for me somewhere between 12.0 grains of 2400 (1475 FPS) and 15.0 grains of 2400 (not quite 1700 FPS). I didn't try running either bullet any faster during the time I had 243s here. I might return to the 243 World at some point, presently I am on hiatus from that sector.

Most def.

My perspective at the time I was shooting 1.1-1.3 MOA five- and ten-shot groups at 100 yards with the RCBS bullet and 12.0 grains of 2400 was more like "If it ain't broke, don't fix it". Grouping largely held up at 200 yards, too--1.5 MOA. So trans-sonic disturbance wasn't destroying things, but wind in Ridgecrest sure as &*^% could and did if I didn't wrap up the shooting by 1 P.M. Warm desert zephyrs......called "Gale force" in some locales.

Inexpensive, accurate loads that my girls enjoyed and that whacked jacks and ground squirrels decisively. If I re-venture into 243 Country again, I might try pushing the envelope a bit harder. I have seen evidence On Paper that 1-8" twists seem to have a fixed cast bullet speed limit of about 1600 FPS (the now-departed 25/35 WCF), and the 1-9" in my Ruger 77R in 6.5 x 55 Swede starts going 'Improved Cylinder' with #266469 at about the 1800 FPS mark. 1-10" stays civilized with a number of 30 caliber bullets to about 2000-2100 FPS in 30-06; this is the same twist used in 243 Winchester. FWIW.

I am an "active target" shooter with cast bullets in my CF rifles. I will set up soup cans in front of a sand berm & plug away at 150 ~ 200 yards. I had been using a Rem 700 .243 Win and the RCBS 95 SP-GC with 10.0 Promo or 11.0 Unique using home made GCs. On a good day (light wind and me doing my part) I can hit 'em 9 /10 shots. The cans are 60mm wide. I also lay used aerosol cans on teh berm and "bark" them....which basically is shooting under them to propel them upwards and/or sideways. Last year I even tried flat tuna fish cans at 175 yards and did surprising well. I shoot for fun and enjoy this type of shooting even more than plugging gongs.

We have pushed a lot into the future understanding cast bullets !
I have no problems shooting NOE 246-105 bullets with gas checks at 2200 fps using RX7 or 2400 in my 243 Win Accurately
I only target shoot
These were shot at 100 yards ( unusual for me)

Very fine results....you can be very proud. I have done some p target groups and none of mine were as tight as our yours.

Wally.... you just have to keep working it up and down a few 10's of a grain at a time: also "bench discipline" is of major importance!
You can have the best load in the world but you need to learn how to shoot it from the bench!
I have found my bestr sweet spot for all my rifles (except the Handi) The front bag is under the factory rear sight.
Also Get yourself some sheep skin -wool on, to put on your front and rear bag....this way the rifle move back smoothly with the recoil! Alwasy reposition it as it was in the last shot!
Makes all the difference in the world

At the casting bench in the sky. RIP Bret.
Gonna have to watch this thread. I have a 6mm Rem on a 98 Mauser that's been sitting unused for 30 or 40 years....

Holy smoke JW, that's pretty bueno!

Well Ian...with the folks we have here it is not hard to learn a lot of good stuff! ( just have to open your mind and forget what "you were always told") :)
Almost all of the old standard guys here have important things to share! I have learned a lot in my time on this forum. ( I have learned a lot from them on other forums when the were there too!)
I have made this information work for me and I have developed, by chance ,information on my experiences that I wish to share
That I think is what we do here!
Thanks You I appreciate your comment!
