Re: 25-06 Ladder Test

8andbait- in response to your question about if i use two different points of aim, yes. this way there is no confusion on which bullet holes is for which load. ie. i start with the lesser charge at the top of the ladder and charges increase down the ladder at each rung or vice versa. this way you can watch each charge seperately and see where your barrel comes ' into tune' i have a very lightweight .300 wsm with a pencil thin barrel and it took around 200 rounds to get it shooting in the mid .3's and even once had a 3 shot group that measured .242. it took some extensive ladder testing and narrowing my loads down to testing by the 1/10th of a grain to get this thing dialed

I've tried it all on my 25-06...My gunsmith pointed me the right direction when I first started reloading. Try 85 or 87 grain bullets with H4350. Work up in .5 grain incriments and shoot 3-shot groups.
It's a 1:10 twist. I have 300 of these bergers so I am determined to get them shooting good. Actually they are shooting plenty good to kill stuff out to 400 but I am trying to refine it down to smaller groups.
I loaded 9 rounds today with 54 gr RL22 CCI200 primers and seated 3 at .010, 3 at .050 and 3 at .090. Not very good results. about 1-1.25" groups for all three. The speeds were really good though with all three loads with less than 15 fps ES. .010 jump has been the best with every powder I have tried so I am going to load up a few at 54.3, 54.6, 54.9, 52.2 and see how they do.

Going hunting tomorrow AM for the weekend so will have to test next week.

Re: 25-06 Ladder Test

The Berger's will shoot great out of a 1-10, your just going to have to find your seating depth with them though.

It might take only bumping them in .005 at a time in order to keep from jumping over their sweet spot but you will see it coming and it will be nice.

I have shot RL-22 almost exclusively in mine since back in the early to mid 80's when I got it. It won't let you down.

Wishin you the best with yours.

What is bugging me is it shot the Hornady factory 117 gr sst into 1/2 moa out to 400. I took one apart and it had 53 gr of a flake powder in it. I dont want to shoot the sst anyway but thought I could get a look at the powder, not sure what it is.

With 54.3 gr of H4831SC I have had several groups under 3/4 inch at 200 yards but have also had a few 1.5-2" groups. I am starting to wonder if it just fouls quickly, but I could shoot over 60 of the factory rounds before it started to spread out.

I like loading and shooting so I am not ready to panic but would be nice to get some consistency. Everytime I think I find something I can't duplicate it.

My creedmoor was too easy, found the load on day one and it still is the load.

thanks, gary

Re: 25-06 Ladder Test

My good friend and hunting bud had a 25 built and was trying out different bullets. He took the time to run close to a hundred rounds through the new barrel to "break it in" something he is not usually accustomed to doing.

Like you it shot the Hornady standard and Light Mag loads into little clusters, but just about everything else we tried wouldn't drop below 1.5".

He worked up to my load of RL-22 with the Partition and it shot VERY well, but still not into the ragged holes of the factory stuff. We also found that both the Nosler and the Bergers did foul his barrel within am matter of around 25 shots, to the point the groups would start to open up even bigger.

That may be the whole issue with yours. It may be building up copper and throwing your groups. I know for a fact the jackets on them are much softer than what Hornady or most anyone else other than probably Nosler uses.

With mine, I simply just have so many rounds down the tube it is WELL polished. I usually only clean it about once a year. She still shoots well enough that I don't mind what little build up we get form the Nosler's we run through it. Then again nowadays we probably don't run 20 rounds a year through it either compared to years ago when I was playing with every new load I could find for it.

About the only bit of advice I could offer would be to possibly run some JB through it on a tight patch and polish it up a bit. I wouldn't get overly aggressive, but I have found with a couple of rifles that a half dozen patches or so, slathered down with JB, and gently stroked through the barrel several times each will polish it up something good.

Re: 25-06 Ladder Test

I agree with the bergers may be softer. I get quite a bit more copper fouling with the bergers than the hornady bullets. This may be the reason for getting the so called flier. Quite a few of the loads will put two in one hole or very close then the third 1-1.5" away (at 200 yds).

I have a few more loaded up I am going to try out tomorrow. I have not cleaned the barrel so we will see what these produce. Everytime I change powder I clean the barrel and start with two foulers. I am going to get some pics up of the groups I shot thursday with the RL22.

thanks, gary

Re: 25-06 Ladder Test

54 gr RL22 .010 jump 100 yards


54 RL22 .050 jump


54 gr RL22 .090 Jump


By comparison this is the CRDMR with 42.1 H4350 with .070 jump at 100 yards



All these were shot round robin style. The CRDMR was shot as the 4th, 2nd and 1st shots in the string of 5 different loads during development. This is still the load and does this all the time, I don't shoot it at 100 yards much but have gotten several groups at 200 yards of this size
