Hello all...this is my first post. I've searched but could not find a definitive answer.
Do any of you know what the velocity will be (approximately) of factory 30-30 rounds (150 gr or 170 gr) out of a 16 inch barrel? I am considering getting a 336 SDG and want to know if the velocity I am losing compared to the 20 inch model is significant or not. Specifically, I am hoping that someone has chronographed these loads out of a trapper.
Winchester Powermax clocks 2305fps out of mine.
Hornady LeverEvolution is 2200fps
Figure that one out.
I think the Hornady is optimized for a longer barrel and burns longer. I'm very pleased with the new Winchester ammo.
So, although the 16" barrel is a handicap, it is not as bad as some perceive it...eh?
I'm curious how Winchester's cheap stuff (Power-Points) perform. Thanks for the reply.
The powerpoints shoot noticibly lower than the powermax. I've never clocked them. Both of them are listed as the same velocity?
The 150 PP's do the job but they shed lead quick.
"Handicap" depends on what you want your max range to be. I'd say for a 200 yard max, its not a handicap.
It's my understanding that the 30-30 with its lower chamber pressure is less effected by a shorter barrel than magnum calibers which use slower powders. The slower powders need a longer barrel in order to have a chance to burn completely. I think that Jakes assumptions are correct about the LE ammo. What's for sure is that a deer won't notice the difference if you use a 16" or a 20" barrel, and I feel that you're wrong by considering it a handicap. I want a rifle with a 16" barrel because it should make it easier to get through the thick stuff without getting hung up. I'm constantly looking for an old beat up 336 just so I can cut the barrel to 16.1" when I rebuild it. Top it with a low power scout scope and I'll have the perfect gun for sneaking through the Florida swamps and palmetto thickets.

No need to worry about FPS loss in 30-30 or 35rem with short barrels.There is very little difference.
Sure there is a difference. It depends on how much MPBR reach you want to achieve.
If the FPS loss is less than 100 fps I don't worry about it.The difference in 30-30 between a 20 inch marlin barrel and a 14 inch contender barrel is only around 40 fps sometimes with the same powder and bullet.If FPS is more important to the buyer get a 308 but if a light short rifle makes somebody happy the 16 inch 30-30 would be a good choice.I like my 16 inch 35rem and 18 inch 30-30 a lot.Where I don't like a short rifle is something that kicks hard with stout loads like in 45-70.
I've found winchester powermax to loose about 11fps per inch compared to 25fps per inch in the leverevolution
Thats a 200fps loss from the advertised velocity of 2400
Thanks Jake thats great info! any idea on the core-loks and how much loss from the 150's and 170's?Originally Posted by Jake
