medium to long range groups

OK...this isnt really going to be long range but given the expertise in this forum i thought this was the best place to ask, so here goes.


i used 30-06 remington 150 core-lokts for close to 40 years. two years ago i had the core separte from the cup on a 140 yard shot. killed the deer but didnt like what happened. i switched to hornady SST 150 grain, shot deer out to 130 yards the entrance holes are big and no exits, didnt like that.


switched to Federal fusion as they have a fused jacket and core, supposedly no separation.


the question: can a certain type of ammo group well at 100 yards and not 200 or longer out of the same gun ?


the fusions group well at 100 yards but are all over the place at 200.


i have never had that happen with the remington ammo

Bohunr, try the 165's, you may find they fly better in the 06. Also, I've found that Fusions like a clean barrel in my Winchester, where Ballistic Tips were not too fussy about it.

Here's three 30-06 165gr Fusions I've recovered from deer. Perform pretty good if you ask me.

Rifle twist is probably it, Fast rwist likes long heavy bullets, slow twist likes short lite bullets, My 7mm 1 in 9.5 i think will shoot anything from 154 gr to 175 great to 200 yards, any thing lighter all over the place,
Do a web search for best bullet for rifle twist.

Good Luck, Stant

my rifle should have a 1:10 twist. its a remington model 700 adl in 30-06 bought brand new in 1983


i have only shot factory ammo out of it as i do not reload. i have always used 150 grain Remington core-lokt until the incident above.


using the calculator both the federal and Remington 150 are OK, marginal stability even in the 165's. i have to find out the bullet length

No exit hole represents a 100% energy dump in the animal. I like that. My son & grandkids live in Idaho. They kill deer and elk every year with either 06 or .243. They use only Fusions in both cartridges. I don't know of any animals going as far as a 100 yds. that they have shot. If you have a bullet that has worked multiple times and is accurate why change because 1 came apart. It did its job, it killed the deer, you recovered the bullet. Don't over think it.
