I want to try the Oregon Trail Lazr Cast bullets 405 gr to work up a load for my 45-70. Oregon trial says they are for the 45-70, but they are .459 dia instead of the normal .458 dia. Does this slight difference mattter? I am shooting a marlin 1895 Cowboy. Any help would be appreiciated.

Thanks in advance

For you gun, you want slight oversized. In fact for my microgroove, I want .460",so I started trying beartooth cause they will make any diameter I want. I should just get me a ballard rifled gun.

Have you ever used the Oregon Cast Bullets? I like the Sierra 300 gr Pro Hunters and the 300 gr Hornady's. I was trying to find something a little cheaper to practice with. My gun likes IMR 4895 w/ CCI200 primers.

I have been using 300gr partitions in front of 46gr 4198. Gettin ready to work up a 3031 load with 300gr sierra. I use oregon trail in 44mag, and my 460Smith. With my microgroove barrel, I just won't spend the money on them with so many bad reports. I have used beartooth bullets.

I shoot the Oregon Trails in all three of my 45-70's. Because they are hard cast, the .459 works extremely well. A .458 would better if you were shooting softer 20-1 or 30-1 lead as they will "bump up" in the barrell. I find 3031 to be the best powder so far. I also, load 3f Goex Express with great results. I'm also, using the Cast Performace bullets and the Beartooth bullets. Between the 3, they are all pretty equal shooters the only difference is the weights, 420-430 grains, for the ones I'm using.
