Are most guys shooting the 5R or any Rem, jumping your bullets, or have you found better accuracy loading closer to the lands? I am talking about the 168smk and 175 smk. Thanks
5R OAL? 168/175SMK / Jumping?

Re: 5R OAL? 168/175SMK / Jumping?
I'm not worried at all about mag feeding, esp coming from a BR background, but most of my bolt guns are custom and using better barrels, like Hart, Lilja, and Krieger, which most of them like it just off the lands. I was just wondering what most LR shooters are loading these 2 bullets. Thanks for reply

It's true...SMKs love to jump. SMKs are jumping in my Rems .030-.065. Beautiful thing for folks that want to mag feed. I have tried many combos with seating closer, but the groups got worse. Sierra takes those things into account when developing. Love those SMKs.

Give 2.825" a try with both bullet weights, it works in both my 308 remingtons with the long leads.

Mine preferred .005 off the lands with just about ever bullet I ran through it.

Jumping works great for me, I tried .050 over max book length on my 175's, then made test bullets shorter by .010 intervals, I ended up finding my best accuracy at the max book length.
Think of some of the most accurate factory ammo available, it is jumping and is within published specs.

With my 5R getting anywhere close to the lands barely left enough bullet in the case to get them to the range without spilling powder
I don't even bother with the amount of jump anymore. I get great performance with both 168 and 175/178 gr bullets (Nosler Custom Competition and Hornady A-Max) loaded at 2.800"-2.820". Can feed from the magazine and the accuracy is consistently in the .25 MOA realm. Rifle seems to care more about powder charge than OAL.

Re: 5R OAL? 168/175SMK / Jumping?
Thanks guys, I shot some more strings of factory 168SMKs and it's still shooting .1's ,and .2's. I have never had a firearm that shoots factory loads like this. I wish I knew what powder Federal Match uses, but I'm going to try Varget 1st.
Also the Brake test I did using Precision Armament, PWS, and JP Cooley, the PA had the least effect on POI, which didn't hurt groups at all, but POI was 1/4" high, but well worth the reduced recoil, and now I can shoot it "free recoil" like my 243's ,6br's, etc. Amazing Brake

I've read varying reports that they use RL-15 or IMR-4064.
Either one gives great results in .308 reloads for the 5R
I still prefer Varget for my 5R. Works great at all distances and temps.

yep, had a 2.963 oal (after adjusted for ogive) on my aac. Was kinda freaked out since the manual says 2.81 is max oal. I walked back by .02's on my smk's and found that the best players were 2.86 for me. That leaves like a .1 jump. crazy. but they like it anyway.
