Re: 300rum ver 7stw

My 300 rum shoots 210 gr smk's at 3225fps that's over 2500 ft lbs of energy at 1000 yds with the g5 drag model, g1 is 1650 I don't see the stw doing that, just my personal opinion.

Re: 300rum ver 7stw

Nathan, while I agree with you that your 300rum load can't be matched by the 7stw, in order to get over 2500lbs at 1000 yards with a 210 smk at 3225 you'd have to be well over 15000 feet altitude. At 5000 feet, where I ran the other numbers it is about 1875lbs. Still about 400lbs more than the 7stw at the same velocity with 168s. So not arguing your point, just keeping the numbers equal. Not many people hunt close to 15000 feet above sea level, at least not in North America.

Re: 300rum ver 7stw

str8shoot is right on. If you are shooting beyond say 800 yards or so go heavy. Right now I am hunting antelope at long range with my 300 ultramag shooting the 208 amax at 3210 fps. I have taken big game animals beyond 1000 yards with a 7mm-300 wby which is the same as a 7mm stw. It was done with the 175 grain SGK which was the only thing we had at that time for long range 7mm's.

These are accuracy loads for one of my 7mm stw's with a 26" hart barrel. 140 grain bullet at 3547 fps. 162 Amax at 3330 fps. 175 SGK at 3218 fps. Run these through JBM or the calculator on the site and see what you get. I have no idea. Either will do the job as I have taken long range animals with both. Anytime you go bigger caliber and heavier bullet you gain killability. Obviously a 105 mm howitzer will kill better than a 22-250. There are small incremental gains as you go up from the smaller to the larger. So I guess the howitzer would kill something deader than the 22-250. Last year my son shot his antelope with a 257 wby and I shot mine with a 338-378 wby. When they were lying there in camp mine looked deader but that may be a biased opinion.

It was showing 2500 ft lbs of energy with the g5 drag model at 400ft elevation and 1650 with the g1 drag model the g5 model matches my drops closer than the g1 model that's why I showed both. I'm using my ballistic app on my I phone it may not be a good way to measure energy but it does a good job using it to figure my drops.
