Say 270 grain 375 and 350 grain in 416, semi spitzer and in both bonded core and non bonded.

So a cheap blow open bullet and a bonded core of same weight and shape.

Sounds alright Mike but what are you getting at

Mike
Why go to the expense of using a jacketed bullet for cheap shooting when a hard lead bullet will do the same!
I have a wonderful 300 grain 375 bullet I shoot in my 375 Whelen. This bullet is both accurate and cheap! After filling the mold with alloy I drop the bullet into a bucket of water to harden it. I size and lube the bullet and off to the loading bench I go. For one box of the super duper gee whiz bullets from Speer, Hornady, Woodleigh I can cast and shoot several thousand of my cast bullets.
I use one of Accurate Arms powders 2520 or 26??, I'm in the process of moving and most everything is packed. I can't access the data books. I'm using 54 to 56 grains of this powder for that bullet.
As the old TV commercial used to say 'Try it you'll like it!'

Jim,

Point of impact, same loads etc.

Actually, the English originally had this system with their Nitro rounds with different jacket and point types in the same weight and shape. Obviously some of that would have related to double rifles.

I've never fired a jacketed round through my 375 Whelen so I cannot speak to the idea of matching an alloy bullet to a jacketed bullet for point of impact etc.
How ever I have read in various gun mags that people have done so.
I've never found that two bullets of the same weight, of different design will hit the same point of impact. The example that comes to mind is a Browning Safari grade 243 I used for deer hunting. This little rifle wanted to be a big bore, it shot both of the Speer 105 grain bullets the best of any tried. The round nose and the spitzer would group into single holes for five round groups. The same powder charge of 39.5 grains of IMR4350 worked for both bullets.
I tried an experiment one fall and loaded up ten rounds of each bullet, cleaned the barrel and alternated the ammo. One round nose then one spitzer until the 20 rounds were finished. There was two distinct groups four inches apart, the round nose one to one point five inches lower then the spitzer. Both goups were outstanding, as was expected.

Jim,

I agree that quite often point of impact will be different with same weight but "different" bullets.

But I was thinking along the lines of two identical bullets, except that one is bonded core.

With reduced loads, I have a 375 here that puts 220 Hornady flat noses loaded with 39 grains of H4227 Extreme about 3 inches under full loads with 270 grain Woodleighs and 71 grains of Varget.
