I had good accuracy with my ER Shaw bbl 98 Mauser in 243. I sold it to get down to 4 rifle bore sizes along with the molds and checks. Then an encore came along and I still haven't bit on casting for it. It shot the remaining 20 bullets I had left well, there is just an easy to find bore size in 7mm or 224.

I understand the "50 yd. being the new 100" idea for the same reasons you (plural) mentioned. While our 100 yd. range was being rebuilt, which took ages, I got used to shooting at 50 and haven't really broken myself of the habit. As for 100 yd. results with #245496, I think I average something like 1.2" - 1.4" for at least 20 five shot groups.

KH, That rifle is even more accurate with 80 - 90gr. jacketed SP's and IMR 4350, "Surplus .30-06" (RVO's name for that ball powder), and lately IMR 7383. (My jug has no lot no. on its label, but it's slower and denser than IMR 4350).

The late Mike Mohler was a CBA competitor who apparently hadn't heard that the short neck and overcapacity case of the 243 were deal breakers. He shot in our production class (max 12 lb. with scope) with a Ruger 77V and regularly was ahead of 90% of the 30 caliber shooters.
In 2007 he won the CBA Grand National Championship (all classes) using a David Mos 95 grain bullet of linotype, sized .245", lubed with Alox/beeswax and pushed to 1,950 fps by 17.5 grains of 4198. His 100 yard records that still stand include: .244" 5 shot group , ..422" 5 shot aggregate as well as .635 MOA combined 100/200yd 5 shot aggregate .
I guess the moral is don't spend too much time worrying about the size of the case, the length of the neck, or how far the bullet hangs down in the powder space.

I have been told many times by my good friend & shooting Buddy ( who has been casting & shooting lead bullets since 1971) "You can't shoot cast accurately in a short neck .223 or .243"
Glad he was there on my first outings with cast in both my .223 and .243!
Easily Bested his .222 mag and 6 mm Rem rifles & loads! He was totally flabbergasted ( as was I too; because i didn't even have the proper cast bullet loading equipment for either the .223 or the .243 - I was expanding my case necks with a long tapered steel rod!)
Never really have been familiar that word "Can't"

I guess I'm either unsophisticated or of the Alfred E. Neumann school of thought "(What? Me Worry?") on this as well because I too don't lose sleep over such things. Moreover, the oft repeated mantra of seating CB's into the rifling made no difference to my Marlin #336 .45-70 either. (I must really be a troglodyte!).

How many guns shoot great when "the rules" are broken?
The only it that matters is the target. If it works, it works.
Best thing a guy can do is ignore the noise and see what the gun and target say.
Results like that in registered competition mean something.

What alloy are you using. I personally don't see why linotype is needed. I haven't cast any yet(to cold) but I'm going to try a bhn of 12 to 15. And mv. Of 1200 or so...any thoughts on this??

At large, whereabouts unknown.
I doubt you'll get a direct reply from KHornet, he's been off the forum for awhile. The original thread is around seven years old. What do you need your bullets to do? At that velocity listed I'm assuming you're target shooting?

Thanks for waking up this old thread. I bought Paul's plain base sgl cav Ideal 245496 mold that's mentioned in the 'snipped' quote above. If you are gonna load for around 1200fps, use a fast powder with a fairly softish bullet (so it obturates). OAL? ...I'd seat to touch the lands. That is the plan I have for the PB Ideal.
If you speed things up to around 1600fps, then your 12 to 15 BHN (COWW equivalent alloy) would be the way to go, with a powder that's a bit slower than what you'd use for 1200fps.
