Vertical groups, next step

[john 800]

I tried some re22 in my 270 the other day and the load I worked up to Is making groups that are less than an inch wide and about 2 or 3 tall at 200.
Rifle specs
Factory 700 24” sporter barrel bedded and flooated in a composite stock
Load
Rem brass,cci primers, speer 130 hot cor, 58 gr of re 22
I worked up to insure the load is safe and I dot see any pressure signs but In order to save componants i never really shot groups at lower charge weights just a few test rounds at each charge weight.
The throat on rhe rifle is very deep, I can’t reach the lands with the bullet still in the case if that matters
At 58 grains I am at book max or close depending on which book you look at. Do I try going up and down a half grain? .3? Or do I try different primers

What is the barrel twist rate? Sounds like you need a heavier bullet which will be longer.

Try some good bullets, did it shoot good before the RE22.... try some Bergers or SMK's 1st, could be a game changer, are you shooting off bags

I never got as good of accuracy using the Speers as the Sierras, Nosler ballistic tips or Bergers. Have not used Speers for many years because of that. In my 270 (when I had it) the best accuracy was achieved with H4831 and RL22. I think you are not anywhere near maximum charge levels. Hunting rifles, more often then not, shoot best when loaded to upper pressure levels.
(Not hot rodded ot dangerous levels) I used 60 grains of either powder with 130 grain Sierras and ballistic tips and got excellent accuracy. 60 grains of H4831 is “The Classic “ 270 load. RL22 is at the same burn rate if not slower. There were no pressure signs in my rifle. Those loads went over the chrono at an average of 3030 fps, basically right where a 270 should be.
Get yourself some 130 gr Nosler ballistic tips and work up to 60 grains of the RL 22 watching for pressure.
For the record, Lyman shows 60 grains of RL 22 with a 130 grain Sierra at 51,800C pressure.

Try H4831 sc if you have some

My stringing groups are caused by the Indian and not the arrow. If I don't load the bipod consistently or have my rear rest stable, sure as carts to horses, I get stringing groups.

Use faster powder and less charge.

I'm certainly no expert, but in my son's 270 Win (that I do all the loading for) those Speer flat base bullets shoot very accurately and kill whitetail reliably. I wouldn't give up on the bullet just yet. Vertical is often a powder charge indicator. I'd go up and down 1/2 grain and see what it looks like. I've also gotten better performance with CCI250's instead of 200's, but these days you have to use what you have. Just my experience for what it is worth.

Use faster powder and less charge.

What COL were you using. I'm trying to run it through QuickLoad. At 70 degrees F, your recipe should be hitting one of the OBT nodes at (I estimated) 3.34 COL. QuickLoad implies that Re23 is a better match for not throwing as much unburned powder out the muzzle.

if I want to advise my buddy where to start, I will suggest this load

Remington's traditionally have long throats. I've owned several and never had a problem with developing precise hunting loads with bullets seated quite a bit off the lands. So, I don't believe this is an issue.

I've never used RE 22 but IMR 4350 and 4831 are proven powders for the 270. Certainly, testing different powder charges is one of the long-established methods of load development. With that case capacity, I would use 0.5 grain increments within published data limits.

However, I've found that the most influential component affecting precision is the bullet selected assuming you are using a powder that is compatible with that caliber. I've also never used Speer rifle bullets, so I don't want to condemn them. However, I found that Sierra, Nosler and some Hornady bullets work very well.

I can't imagine CCI primers causing the problem. They have been used for many years in the 270's with outstanding results but nothing is absolute. However, I wouldn't suspect primers at this stage.

I assume you have checked all scope and stock screws for tightness.

So, it sounds like you're getting vertical stringing. It might be helpful if you described your shooting process when testing loads, i.e., type of rest, shot sequence, position of rifle on front rest.

I use a good barrel tuner to eliminate vertical.

 

[Doom]

You really haven't worked up a load. You're shooting a load/seating depth that isn't tuned. You need to either work up a load (OCW) for the COAL you are seating to or work this load with different seating depth.

I had a very similar problem ... did weeks of troubleshooting. Long story short ... it ended up being a broken scope. Went back to Leupold for a fix, and shoots lights-out now. Repair order said the "elevator" was defective.

 

[john 800]

Lots of help and questions here…
The rifle will shoot pretty good with 150 balistic tips seated way out, too long for the mag, shoots decent with the 130 hotcors with imr 4831. I have a bunch of the hotcors and the re 22 I load in another rifle so I would like to try to make something work with that combo.

I dont have any idea what I am looking at there. What are the issues?

Selected powder is very slow for the bullet/caliber. It is not a good match.

Also make sure that the scope and the scope rings can hold zero.

 

[john 800]

I sure appreciate all the help from everyone. I will have to dig into it deeper next week and come up with a plan. I will be heading out on a hunt tomorrow.
I will look at my notes for the question about oal measurements

 

[tclaunch]

I 100% agree with advise given to go on up to 60 grains and enjoy the learning curve.
