Hey, I have just purchased a 1/7 LMT M4 upper, and all I can find on 1/7 twist every one bitches "go to ammo oracle" but it mostly covers mil surp rounds! Can any one tell me of a good varmit round that will make jackrabbits explode? Will 55 grn hollow points be heavy enough? Will ballistic tips stay togher better? Any one have a load they prefer?? Thanks, Fisty  

No one has any practical experence with varment loads an a 1/7 twist??hinking.gif

i don't see why any old .223 hollowpoint wouldn't make a rabbit explode.

If you are talking about accuracy, and you are a reloader......., the Sierra Varminter 63 gr.  Semi Point #1370 in front of 24.5 grains of 2230 is the most accurate combination I have ever found bar none!!

I shoot this load in my 1:7 M4 & 1:9 MT6731 AR's and in my 1:12 Rem. 700 LVSF

Extremely accurate  in all three..., and very explosive on critters!!

I think the biggest reason it is so accurate in the AR's is that
the "Semi-pointed" bullet has a faster tapering Ogive (rounder nose design) which allows you to have the bullet seated  to almost touching the rifling lands when the round is in full battery, but still have a short enough OAL to fit in, and feed properly from the magazine!  

Without exception....., all other .223/.224 bullet weights & shapes I've tried do not come any where near close enough to the lands when chambered to produce any real accuracy when seated short enough to fit into a AR mag!!

As for factory loads..., Ive never found anything that you could call "extremely" accurate!!

Although I have heard a lot of good stuff about Blackhills Ammo!!

For great ammo, get the Winchester 45 grain HP.  It works fine, even at a full 3600 FPS from a 1:7" barrel and should still open up from a short barrel.
