    I know the 300 Win mag is best noted for pushing the heck out of 150 and 180 grain bullets. But how does it do with the 130's and 110's. The 300 mag is the next gun on my to buy list and I like to do a little reloading research before I go down that isle of the gun shop the day I buy the gun.

    If u guys have loads you like I'd love to hear them and if you got pictures of groupings that's great too. I plan on getting some 150 and 180 grain bullets for deer and elk hunting but thought I might pick up some lighter ones too for deer/varmints and paper. Thanks guys.

    ive never shot light bullets in mine,i have a 300wsm and i only shoot 190gr bullets,but if you take a trip to your local gunshop they should have free pamphlets from the powder manufacturers with load data that are very helpful! or do some reading at reloadersnest.com . i have a few loads ive published there for differant calibers. they have group sizes and alot of info for reloaders.

    I do believe you will find the safe loads listed in the reloading manuals by Speer, Sierra, etc...

    the current lee manual has load data as light as the 125 grain which i am actually going to reload a few and try them in my 300wm.

    I haven't tested any loads in the 150-165 grain range since I leave that class of bullet to my 308 Win. For the 180gr weights you will do well with R22. I have not used R22 for 180-190, but based on my research and others results I believe the burn rate is most appropriate for these weights. For heavier bullets in the 200gr+ class H1000 is the best going atm IMO, with R25 being a close 2nd.

    The 208 Amax has worked well for me an R22, but I am sure the H1000 I loaded for ladder testing when I get out to the range next week will be a little tighter grouping. For the 208 Amax I'm getting single hole groups at 72.0 grains @ a tested 2920 fps (tight molly barrel in SAKO TRG42) in 108F degree weather. The thing is my bolt was pretty stiff, so I'm going to back down .3 grain increments and see how that works out. I did also have good results at 71.0gr. (3/4 MOA) I was using WW brass, Winchester Mag Primers. If you choose to try these loads out do so based on your reloading manual working loads up as I'm sure you already know. I'm sure that the H1000 will produce some better grouping without having to push them so hot. I know my TRG42 is capable of better groups than 3/4 MOA.

    Good luck in working with whatever combination you decide to work with, and please post your results.

    I once owned a Browning bolt three hundred mag

    Yes, there are lighter bullet loadings but honestly I did not find the accuracy. However, others may have better experiences.

    Best wishes.
