300 win mag
Is it possible to reload 300 win mag light enough to compare to a 30-06 or a 308 (a deer round) without going as light as the managed recoil rounds?
What kind of powder would you use and how much? |
RE: 300 win mag
Look in your load manual and start with the lightest bullets and powder charge and work up till you get what you want. CJ

RE: 300 win mag
Get published reloading data for 150-168gr bullets and start near minimum loads. This will get you what you want. Choose a tough or bonded bullet, impact velocity could be pretty high (no Ballistic Tips).

RE: 300 win mag
This only works with the lighter bullets in that caliber. Hodgdon has youth loads, using H4895. You take any load where H4895 is listed, and multiply the max charge by 0.6. That is as low as you can go. This will be much lower than you want to go, but you can use any charge in between.
Checking their site, they have data for h4895 up to a 168 gr. bullet. For more info, see the youth loads on the Hodgdon site. http://www.hodgdon.com/PDF/Youth%20Loads.pdf |
RE: 300 win mag
My experience in loading for the 300win mag is that they like near to or max loads, Ive tried light loads and cant come up with anything that is near consistant or accurate. If recoil is the culprit, you canadd weight and a good recoil pad to minimize the felt recoil.

RE: 300 win mag
Thank you everyone. I looked in an "old" reloading manual and found a load which may work. The load is as follows:
Bullet : .308" dia, .225 sec. den., .423 ballistic coef., and weighs 150 Gr. Powder : 760 powder 64.0 to 68.0 grains (bullet speed muzzle:2732-2973) Primer: CCI 250 I calculated the bullet muzzle energy for this load and it is around 2610 ft-lb. The 180 grain 30-06 had around 2500 ft-pound (both muzzle energy). Some 300 win mags show 3100-3300 ft lb with 180 grain bullets. Would comparable muzzle energys translate to comparable felt recoil? Would this be a good deer load? (It seems like it to me and it is not too fast so expansion should be ok) |
RE: 300 win mag
I can understand doing this for getting someone accustomed to the recoil, maybe a bit of practice or possibly to reduced damage to meat. But if you plan to do this often why not just buy a .308 and be done with it. Sell off the big gun.
Yes it can be loaded down, no you will have to get your loading info from a published source. ??? |

Would this be a good deer load? (It seems like it to me and it is not too fast so expansion should be ok) I calculate a full house 300 win mag load at about 30 ft lbs recoil energy for a 8.5 pound gun using 180 grain bullets. Your load listed above is 17-21 ft/lbs which is comparable to a .30-06. This is sort of a guess, as the gas velocity is unknown. Hodgdon used 4700 fps, I use 1.5 times muzzle velocity. |
RE: 300 win mag
skb, thanks for the advice. The load is from a Speer reloading manual and is one of their standard loads the powder is 760 not H760 there is a difference. I do plan on using the rifle for Elk which is why I like the 300. When elk hunting I will use the typical elk loads. I just don't want to kill my shoulder if not necessary or ruin more meat than necessary. Does that sound like a bad load? 68 grains of the 760 powder is max load. Has anyone used the 760 powder with a 150 gr bullet?
