Has anyone ever worked up a load for the .300 Win Mag, using a 100 grain Lapua bullet, or any other 100 grain bullet?
My 300's shoot great with the usual 150 - 200 grain bullets, but I'd like to see if I can come up with a load that is considered "legal" to hunt chucks with here in NJ, and you can use larger than .25 calibers, BUT bullets cannot exceed 100 grains? I know, this is off, but it would be fun to play with, safely...

Are there 100gr or lower .30cal bullets out there?
I have loaded the 110gr V-Max for my 300WM, I believe I get around 3800-3900fps, I'd have to look it up. Even seated out as far as I can and still have them held in the case, it's quite a jump to the lands. Yet they are accurate...and explosive.
I don't shoot a lot of them. You'll smoke your barrel right quick shooting those light bullets that fast.

Hi Spaniel, Yes, Lapua is one manufacturer that I know of makes a nice 100 grain hollow point bullet called the Cutting Edge ( www.lapua.com/en/products/reloading/bullets/centerfire-rifle-bullets/11 ). From what I've found on the web, either RL-15 or WW-748 powder has been used, but how much so I "don't smoke the barrel", yet still get decent velocity (~3,000fps is OK) . I'm new to reloading but my buddy, who will be making these loads, is not. I know that when I compare a factory load to a dummy load to see where the 180 grain bullet touches the lands, there is 6 mm of room before the bullet touches the lands! On a 100 grain bullet, I hope there's enough bullet to seat it properly. Too bad they don't make a 100 grain .308 bullet that is the same length as a 180 grain bullet, but has the insides hollowed out, sort of like a reverse hollow point....a thimble? Any additional advice would be gladly welcomed.... |

I'm not sure what you could use to load them down and still maintain minimum pressure....I shoot few enough I went the opposite way and stopped before I entered compressed load territory...Re22 I think? I'm far from max pressure.

I think there is a fairly simple solution. Go to : data.hodgdon.com/cartridge_load.asp and look up the data for 300 win mag and the 110 gr bullets. Check out the pressures and pick one that looks like it would work for you and simply use the 100 gr bullet in place of the 110. Personally I would look for the load that was running the highest pressure with the 110 gr bullet and maybe even with a C following the charge weight which stands for a compressed load. I would venture to say you would easily find a load that would give you over 3000 fps. Accuracy maybe the sticking point, but if you can get Minute of Chuck out of it out to 200 yds or so it may be worth the effort. I doubt over pressure will be a problem but it is good to have someone helping you who is experienced. Perhaps a phone call to Lapua would be in order for some load data as well. |

I appreciate all the advice and will pass on to my bud who's doing the reloading (and test firing) for me.

Geez, the B.C. of .170 on that bullet makes my muzzle loader bullets
look good! ;D
Wonder if anyone out there makes a 100gr or less bullet like the
Varmint Grenade in .308? The .204, .224, and.243 VG's have a bearing
surface long enough to seat out to the lands if needed, but I don't
believe there's anything like that by Barnes or Nosler for .308 bullets.
