ebb ,ill got 3 ,30cal rifles two semi and bolt love them,but i was shooting 338lm the orther day at work love the down range affects. the 338lm the cost the ammo is out of this world.so i did some math and compters suff and the 338RUM is the so close in fps in 300grs mks with 29.5 ,with speed of 2900 to 3200fps ,using cold powers you could shoot 2000 to 2500 round out of rifle insted of 1500round like 300RUM and bunedout barrle
I am launching 300 smk out of my 338 Lapua @ 2900 fps, the fastest I got it was 2937 fps, this is out of a 26" pacnor barrel, my loads a pretty hot, but I could probably get 2880 fps with some pretty reasonable loads.
The ballistics of the 300 grain smk at 2900+ fps is awesome, it has the ability to go to 2000+ yards.
The numbers are better on the 300 smk and i was sure they would be, but they are not enough better to make me want to change. I play this game on a limited budget and the dollars spent to go to a 338 LR gun cant be justifed BY ME, i am sure that in alaska a 338 would be very usful and maybe manditory. I do have a 338 win mag and have killed elk with it and love it. The number of bullets in 30 cal is also a selling point to me, what if you had a 338LM or rum that didnt like smks the others with a high bc get pricey quick. Some day maybe a 338 or 40 cal but right now all funds are going to a 6.5 284 . thanks ebb
Ebb try a 116 savage weather warrior in 300 rum it is the poor man's stole when you get ready for another barrel just buy it to fit the savage and change it out. You don't have to be a rocket scientist to perform this task. ( don't take offense to this Don !!)Lots of good barrel makers the ones listed above are great.
Sniper 2 I already have a sendero in 300 RUM and i love it, broke in the barrel over the spring ( we get to use the sheriffs range once a month ). Tried loads of wc872 from 93 grains to 98 grains with 220 smks, and 210 bergers with 96 grains. The bergers would not make it to the target at 1000yds, the 1in10 twist spins them to fast. The 98 grains with a 220 smk is a keeper, it showed no signs of presure, but it will only get warmer here for a long while so i droped a half grain and loaded 50 of them . Iam kinda new at this but i hit sky kings steel disc 4 or 5 times at 1000yds with about 1 mil of wind. Every one talks about wc872 being temp senstive so i may not push this load any further. ebb
