Come on bullet makers!!!

I mean really! when the heck are bullet makers going to make a really good 30 cal projectile?
Dont get me wrong the h 208 and b 210 are good and can shoot past a mile even in 300 wm however they do not bring out the full potential of the 30's! smks really are not a vld design and don't preform as such (still a good bullet) but what I/we as long range shooters really need is a secant ogive bullet like the burger 210 and hornady 208 with a bearing surface that makes jump easier to deal with! something in the 225 to 230 range would be premium! It should have just as high or slightly higher bc than the 240smk but still get better volocity!

Re: Come on bullet makers!!!

The problem lies within the standard twist rate barrels in 30cal. Its not the projectile makes fault... The standard 1:10twist barrel would not be able to fully stabilize a 230gr VLD shape bullet. It would have to be very long in order to have a secant, large radius nose and 230grains in weight.

And whilst your asking for something in .308win, how fast do you think you can safely push a 210gr bullet, let alone a 230gr???

The 308win is already flat out pushing a 210gr @ 2600fps if your lucky... There is nothing more to be gained by going to a heavier bullet because what you gain in BC, you will loose in velocity and time of flight. This is no longer true for the big 30`s, as they have plenty of velocity already, they are simply lacking a bullet with a higher BC.

Its the BIG 30cal cases that would benefit from a heavier VLD... but again, its only possible if people suddenly start buying faster twist barrels to shoot them... but why would you buy a faster twist barrel when you dont have the bullets available...? chicken or the egg, catch 22, conundrum...

Re: Come on bullet makers!!!

I've wondered the same thing and have looked for other options for my 300 RUM. I've ran data comparing the 200 AB (which I shoot now) against the 210 & 220 SMK as well as the 210 Berger and don't see a lot of difference.

Now, check out Hornady's website. They are showing a new match bullet that will be available this spring. It is a 225 grain with a .670 BC. I know Sierra doesn't recommend a 9 twist until you get to the 240 so I would assume with proper velocity a 10 twist should stabilize this. I am looking into this new Hornady and trying to find any info on how well it would perform as a hunting bullet.

No doubt 30 cal has been kicked to the curb when it comes to high BC projectiles, as compared to the 7mm and probably even the 6.5mm bullets.

I know that a couple of the lathe turned manufacturers are producing solids that are designed to work in standard twist barrels, but the BC gain so far does not seem to be worth the price paid.

But its still a good goal, standard twist, higher BC, nominal price.

If they build one off their 208 amax it should show close to .7!
i am excited to test out these new bullets when they do hit the market!
when i ran theretical numbers based off of current 225 volocities the comparable volocities and bcs put the 225 and 208 nearly identical @1760 however if you take the difference from the 208 bthpm @ .62 (expected)and its brother at .67 (expected)you have .05 then add that to the .648 (advertised) of the 208 amax you'd .698 wich would give a good edge to that weight selection! the velocity/bc of this combo would also out perform the monster 240smk
weres berger on this one?

I maybe off base here but I am not sure how much more bullet weight the 308 can handle than the 208. You cannot get enough powder in a 308 to make anything heavier than a 208 have any significant velocity. At least not enough to make the higher BC worth while. If the 308/208 AMAX isnt enough for you then you should most likely be looking to another cartridge. The 308/208 combo is nothing to sneeze at as it is.

My idea of a perfect 308 winnie bullet is 175-190 grains with a .6 to .625 BC that will expand on game as low as 1400 FPS and hold together on a shoulder shot at 2800 FPS. A 190 with a .625 BC would be about the best overall balanced bullet between speed and BC. Typically from a 26" barrel a 190 can be driven any where from 2600-2750+ with the right powder. Even at that, the 190 with a .625 BC would only have a very small benefit in wind and energy over the 208. The real difference here would be a combo near that of the 308/208 with a bit less recoil and a bullet that will hold together a bit better at close range.

Kind of sounds like the 177 GS bullet except I cannot bring myself to believe that the published BC is any where near reality and I would need a new barrel to stabilize it. I would gladly get a new barrel if I thought the BC was close.

My answer to this is. The only reason is to make the 7 RM look good. There is no other reason.
