Here are the findings of the day. My good ole shootin bench ain't gettin it. I'm not going to be able to see what this rig can do until I finish the new bench. But I have pics to show where things are with what I have. This one is Nosler 140gr.BT. The group on the left is 3.285 oal. with 53.5 grs. IMR 4350. And the group on the right is 3.285 oal with 55grs of 4350. All groups were difficult due to a less than solid bench. ( the center square is 7/8" X 7/8")
#2 is Barnes X 140gr. HPBT. On the left is 3.22 oal with 53.5grs. of 4350 and on the right is 3.22 oal with 55grs. of the same.
#3 is Serria 140 HPBT. On the left is 3.17 oal with 53.5grs. of 4350 and on the right is 3.17 oal with 55grs. of 4350.
#4 is Winchester 130gr. PP. On the left is 3.205 oal with 53.7 grs of 4350 and on the left is 3.205 oal with 55.5 grs. of 4350.
#5 is Nosler 150gr. BT. On the left is 3.287 oal with 52.4grs. 4350 and on the right is 3.287 oal with 53.4grs. of IMR 4350.
Over all I am not pleased with what I am getting, but I know patients is required and a better bench will help me get what this rifle has to offer. All the 140gr. seem to hit tighter with the hotter load. The Winchester 130's show potential with the 53.7gr. load. I may give it one more try on the new bench and the Nosler 150 and 140's both show to be high in the keeper list. The Barnes 140's probably won't get another chance, but I'll try the Serria 140's on the new bench with the 55gr. load. I would like to try a little more powder with the Nosler 150's but it would be compressing the powder in the case and I'm not comfortable doing that.
If anyone has any pointers I'm all ears.

Are you using a backing on those paper targets ....cardboard or wood cuz those holes look kinda funny not true circles kinda oblongish, just asking?

It is a wood back stop with the targets taped down. The holes are probably flattened some from being stacked together on the ride home.

You may have to work on different OAL with those that are showing promise. To find the potential on your rifle quicker, maybe only use one bullet type and weight. Currently you are working with 4 variables, bullet type, weight, powder weight and OAL.

Your right, I started with the various bullets because I didn't want to let predjudice of a favorite keep me from a better round. I do want to stay in the 140/150gr. bullet wt. if possible. I loaded a few of each shown above that were in the lands and to my suprise the ones just off the lands were alot tighter. I could use your advise on how much to adjust since a shorter oal is the only direction available. I am impressed with this rifle as barrel heat seems to have little effect on POI. I have tried letting it cool after each round and firing 5 and 5 with the major factor still being that light duty bench. If I were willing to accept hunting accuracy any of the bullets tried would be fine. I'm looking for the best group for distance. I am also wanting to push the velocity some, that is one reason I had the heavy barrel. I'm gonna have to get some other loading manuals because the Serria is a bit limited in selection. I plan to load some Nosler 140's and 150's, Serria 140's and I may try the Winchester 130's one more time for the next range session.
The IMR 4350 has a very good rep for consistancy.
Does anyone think another powder might give me added velocity potential without blowing accuracy. These last loads were in the 3000 range according to the Serria manual. And the powder measure was maxed in the case without really compressing with the oal I'm useing.

Hey sarge,
If I were to start reloading again for the .270 Win I'd be trying the RL powders. These are per the Nosler #4 manual:
Universal receiver w/24" Shilen 1-10" bbl
140gr BT w/Fed 210 primers and RL19 powder in Win casings
51gr at 2779
53gr at 2891
55gr at 3003
150gr Partition or BT w/Fed 210 primers and RL22 powder in Win casings
52.5gr at 2672
54.4gr at 2787
56.5gr at 2902

Don't forget about the new formulation RL17. Similar to IMR 4350 in burn rate but generates more pressure for same grain weight. I had good results in my Sav 270win using it. Just start with a charge 1.5 to 2 grains less than you use for IMR4350. I found I could shave at least one grain off the charge and still beat the MV of the IMR4350 by 50-150fps with good consistancy while maintaining the grouping size.
Looks like she is liking the Sierra 140 HPBT the best so far. Have to agree with Wouter.... reduce teh number of variables and I think you'll get better results faster! It also means you'll have to shoot more, A very good thing!

I had dropped this thread for awhile due to hard to accept loss of the ability to hold for the shot like I use to. I've discovered that the combination of back and shoulder injuries and the meds taken to help with pain have robbed me of things I have taken for granted. On the up side I may have discovered that this rifle groups better at 200+ yds. and I may have to adjust my thinking to accomidate. I haven't taken oppertunity to prove or disprove that posibility yet but I expect to do so before this coming season. I have found that it is remarkably reliable at any range I have seen fit to dispatch an animal. Infact one occasion showed me that dialing to "in the ballpark" is not such a good idea. I made the kill but, it wasn't as "in the ballpark as I expected. I am very pleased with the rifle and as expected it is far above my skills at this time. As I try to find ways to overcome some physical short commings I hope to regain some of those things I had lost. Never the less it is a joy to shoot and I hope to post some decent range targets in the near future.
I also plan to try the powders you all have suggested. That being said the Nosler 140's are waht I have loaded since I last posted here and have ordered some 140 Bergers to try on my next range session.
Thanks for the suggestions and thanks for bringing this thread back to life.
