O/T WINCHESTER 458 MAGNUM CAST BULLETS

[gary rice]

Just curious if anyone has used cast in the model 70 and what the results were. Those 500 grain hdys are getting expensive. Ive been thinking about the beartooth 525 grn cast with a gas check.

I load a gas checked 500 gr Lee bullet in a custom Ruger Num 1 in 45-70
It shoots really well though recoil is stout. The barrel has a 16 twist so that should be getting close to what a Mod 70 458 will be

Here is a target to go with the rifle pic.
I think 458 win mags are generaly quite cast friendly

Not to 'divert' the thread, but sometime post more about that gun...

I have a 7mm Rem Mag Ruger No.1 that I either want to sell, trade, or re-barrel, and that gun seems to be a natural for a 'thumper' vs. a 'ultra-long-range tackdriver' like the 7mm Rem Mag.

Not a 458 but similar in bullet weight and speed, my 470NE shoots 500 gr. gas checked cast bullets just a good as jacketed bullets. It seems that the larger the caliber, the easier they shoot cast bullets accurately. I cast these myself and heat treat so they are rather hard. I think you'll be pleased with the Beartooth cast bullets. Here's one of mine with a 22lr for comparison.

Make sure the bullets are at least .460 diameter. You must fill up the throat on a factory 458 chamber or accuracy will be poor. You are better off cutting off a half inch of barrel and rethreading and recutting the retarded factory chamber with a non saami reamer instead of having a funnel throat that can measure up to .470 diameter.

I've shot the 500gr RCBS, about 525grs, through my M70 .458 for 25 years. I just use how ever much 3031 I can stand at the time. Excellent accuracy at all velocities.
