Just a quick question. Do any of you guys have a "pet" 308 load that you use in your 5R with 175 SMKs using IMR 4895?
Thanks
 
Re: Rem 5R 308 guys

I've only tried 2 powders. IMR 4046 and Varget. Varget shoots much better. 300yds 4 shot group .067 inches. The 5th shot made the group 1.17 inches.
 
Re: Rem 5R 308 guys

I have 2 loads that I shoot.

178 AMAX (when I can find them)
Lapua Brass
44.8 Gr Varget
CCI BR2
2.838 COAL
.0015 neck tension with Redding FL Type S dies and Competion seater

175 SMK (when I cant find 178 AMAX)
Lapua Brass
45.1 Gr Varget
CCI BR2
2.810 COAL
.0015 neck tension with Redding FL Type S dies and Competion seater


When I do my part:
either will shoot 5 shot groups smaller than a dime @100 yards
and 5 shot groups about 3.5" @500 yards, Some a little more, Some a little less

The AMAX is much more consistant

Edit:

In case you do try these loads work up to it and make sure you dont have pressure signs. These loads are hot. Also dont try this with another brass.

 
Re: Rem 5R 308 guys

damn Repiv 45.1 gr of varget woth the 175 smk? Whats your FPS. I run 43.0 @ 2550
 
Re: Rem 5R 308 guys

I dont know, I just bought a crono. I will see what it is this Friday and let you know. It does shoot good though and no pressure issues.

BTW I also had a good node at 43 but 45.1 is better.
 
Re: Rem 5R 308 guys

imr 4895 2500 fps as per the book lyman book

regular cci primers
178 grain amax
2.810 oal
r.p. brass

less than 1" @ 100 yards w/ rem 5r milspec

with the 5r make sure it is above 2400 fps to get the whole thing working properly.

i found that below 2400 fps the groups get too big

edited for grains being wrong
 
Re: Rem 5R 308 guys

2500 seems slow for the 178amax. I'm getting 2640 with 42.5 grains of Varget and that is nowhere near max.
 
Re: Rem 5R 308 guys

i stated the grains wrong. sorry. i had to recheck my facts.

2500 fps is what i was going for. i wrote it wrong.

i will get my load tonight. sorry about the confusion
 
Re: Rem 5R 308 guys

I know you want the other powder but I love re15.

175gr. SMK
Win brass
BR2s or Fed 210M
44.7 gr.s of RE15
2.810 OAL
2660fps

trying to replicate 118LR out of the stock same exact MV out of 2 5Rs
1\4-1\2moa. those guns are great!
 
Re: Rem 5R 308 guys

This is my load with IMR4895. Seems like most guys moved on from this powder though. I got some Varget but never had good results with it so I stuck with IMR4895. Anyways, with the below recipe, I shoot from .25-.40MOA @ 100.

155 AMAX seated touching the lands
42.8grn IMR4895
Winchester case trimmed to 2.005
CCI 200


I can't remember what my chrono read on top of my head but I would say somewhere in the 2600fps range I believe. Need to pull my data book to find out.
 
Re: Rem 5R 308 guys

I know you were asking about 4895, but I tried 3 different loads tonight in my 5R, all were .3 or .4 MOA.

All bullets were 178 Amax

43.5 Varget, 2.800 COAL
43.5 RE15, 2.830 COAL
44.0 RE15, 2.830 COAL

Dont know the velocity, since it was done at night. These powders also have very, very little muzzle flash, just FYI.

Re: Rem 5R 308 guys

You could try 41-43.0 grains ...

Note I have had much better luck using Varget with 175 gr bullets.
