30 inch barrel loads??? in 300 win ??

[jvm]

I have a new 30 inch barreled 300 win mag;

For long range loads with 190s (or other bullets) what would be some good loads? Action is a 700 Rem.

Those praire dogs are in trouble...I hope
Thanks

Only person I know with a barrel that long in a magnum loads sierra palma bullets. Depending on your twist it might be worth a try. They will come out of it really fast.

You would benefit the most with the heavy bullets, like a 208 A-max, 210 VLD. Depending on your range, you could load up some 155's for flat shooting. I'd look at Retumbo and a 208 as my first choice, though.

I run a 28" Rock barrel and 190VLDs to the lands, Lapua case, Fed Match primers, 70 to 72gr R22 powder, that should be around 3100fps and no bolt stick (depends on your chamber and what-not)

In my opinion, shooting the lighter bullets 155-175 is a waste, you don't get a great increase in velocity so you might as well get the punch from a heavier bullets 190-220

I was hoping someone had chronagraphed a long barrel 300 win,

what the reloading books say and what is real some times don't match up

Re: 30 inch barrel loads??? in 300 win ??

too many variables, barrel lenght, chamber tightness, primers, brass, bullet, seating depth, powder burn rates,,,etc.

Really have to load some and find which shoots best at a velocity that you are happy with.

Plan for about 15 fps gain per inch of added barrel length, give or take a few fps. Plus, it all depends on what load the rifle likes to the velocity you get. I can get 2850 fps easily with a 208 A-max in a 27 1/8" barrel. You can push it faster with a slower powder up to about 2950 fps, plus your added barrel length. A 190 grainer can go 2950 to 3025, maybe a hair faster. A 155 should run about 3200-3300 fps at max charges, then add your barrel length. A 110 grain V-max can run 3750 to 3800. This should help.

You don't need much punch for prairie dogs. For 300-500 yards, the 155's would be smokin' for a p-dog town with little drop. A 110 V-max would be total carnage.

155's from a 30" barrel should be very fast. You may end up not reaching the target because they self destruct. I shoot them at 3100 for accuracy from my 30-06 and 26" and I've gotten over 3200 when I really lean on em. Start with the advice here and work up from there, that's the best approach IMO.

? why would you burn out a 300wm barrel on prairie dogs, sell the rifle and get something that uses less powder and cheaper brass ? Even a 308 would last 8x as long and cost a lot less to reload

300WM for prairie dogs? Man those must be some giant prairie dogs...

Re: 30 inch barrel loads??? in 300 win ??

I have a 300WM hunting rifle, and I won't shoot it a lot, maybe 50-75 times a year, if that. So, if you get 1500 rounds out of it, that will last a long time. Why not have a hot rod 300WM. Velocity does kill!
