Home Forums Hunting & Shooting Hunting Rifles 300 win mag bullets

i dont wanna think how big of a pain that would get having to tweek a load to work great in several diff rifles..i only have 1 rifle in this chambering, for now..and w/ me just getting into to the reloading world, i dont wnana frustrate myself too much lol

That's funny and smart. Just take it one step at a time and read through some good manuals. Speer, hornady, nosler, sierra etc.. The key to reloading is being safe and aware. A lot of guys here are very knowledgeable in reloading. I do have one question though. I had a friend that was stationed in your area for some time, his name is Mark Hurley. PM me if you know him from the base. Take care.

i just got to this area, so at least for right now i dont knwo too may people that are stationed here..but in the next few months i plan on diggin deep into reloading manuals for my 300 wm and my 243 win...lookin heavily at hornady interlocks right now from good reviews and affordable pricetag

My 300 win mags and my 06 shoot the 165 Hornady Interlocks very well. Great bullet for most any game animal and definitely one of the better values in bullets.

As far as my .243, It likes the 85 grain barnes bullets over 38 grains of Varget and shoots the 58 grain Hornady v-max over 44 grains of varget into little dime-sized groups all day long.

im thinkin the 165 interlocks like your set up..wrote down the load data you posted on here as a baseline to try out...but im lookin at tryin either the 100 grain interlocks or the hornady sst's in it too..not positive what bullet i want for the 243 just yet

I can send you some of my data on the 300 win mag if you like. I have spent years developing loads for this round. I have some very close friends, one of which built one of the 300s that I shoot with each weekend. We normally spend all day Saturday shooting, mostly with handguns, 308 rifles and 300WM rifles along with some machine guns on occasion (guy who built the rifle for me is a WWII collector). I can send you a PM if you wish with some below maximum loads from which to start with the 165 gr IL.

You likely won't have to dig much deeper than RL22- at least for 180's or 200's. H1000 is another good one with 180's. But RL22 is the shizzle.

I agree, but I've had good results with H4895 and great results with IMR4831.

you guys are awesome!.if you dont mind sending me some load ideas for my 300 that would be awesome! do you by chance have any good 308 loads w/ 150 or 165s?lookin to start a build on a LW mountain rifle in 308 sometime after my wedding.

Looking back over my load data shows that RL22 is in fact the shizzle. I have more good loads listed for it than all others combined! In fact, 75.4 grains and a 165 IL or IB give me the best accuracy, and velocity over 3000 fps.

RL22 has long been a very good powder for the 300 Win Mag....have used it in that cartridge since it came out...and about 76 gr with the 180 has always given about 3100 fps,depending on which bullet and barrel.

+1, RL-22 for the .300 Win Mag. It would have to be on the short list of best powders for that caliber.

Both the .300 Win Mag and the .308 Win was very forgiving and easy calibers for which to develop good loads. I try to not have multiples of one caliber for the reason mentioned. With loads and brass specific for each gun, having several in a caliber is just like having different calibers.

BTW, H4895 with 150 gr. bullets was the tack driving load for my .308.

165, 180, 200 grain acubonds, BT's or whatever.

R-22, H4831sc or H1000.

You will never need or want anything else for your .300 WM if you pick from this list.

H4831sc (one of Hogdon's extreme line of powders) and Acubond 180's (great BC) covers all bases.

Good info guys!...i really dont know much about powders besides what ive read online and looking at load charts

R22 or H4831SC for 180's in th 300 WM

Oh don't get us started . My favorite load for the 308 and 150 hornady interlocks (spire point flat base) is 47 gr. RE-15 usually seated about .015-.020" off the lands. CCI 200 primers and winchester or remington brass usually produces less than 1 moa in 3 of my 308's. Remember to work up to that load (although it isn't quite book max).

You guys are like my saving graces! Lol..there isnt much u guys dont have 3 diff stellar loads for
