Reloading questions / help

[carpsniperg2]

With your 243 the twist in your rifle probably like the heavier bullets by the sounds of it. If it likes the 100 grain bullets then do some light handloads with the 100 grain bullets. Load at the recommended minimum for whatever powder you are using.

On the 270 I would buy a box of factory ammo and try it at 100 and 200. If it does the same wild thing I would be second guessing the mounts/rings and scope. If it shoots them better. I would guess that gun does not like that load and maybe go to a light bullet and try that.

 There are so many things it could be but in my opinion if you are getting factory ammo to shoot better than your reloads you are not doing something correctly . This can be anything from seating the bullets - not the right powder on and on . I can not understand why guys like heavier bullets out of a .270 ..it was made for 130 gr and lighter ...BUT I do find 140 gr to be the perfect bullet ..just shoots great and a little more knock down power without going to heavy ...as far as the .243 I would go with IMR 4350 ..just always has been my go to powder for a 243...another little trick when seating the ball into the case is to seat the ball a little at a time and spin the case about 1/4 turn and continue doing this until the ball is seated ..Takes a little more time but it does make a difference when your trying to load tight loads ..

I have contemplated going with a lighter bullet except I have so many 150 grain partitions it is hard not to use them.  I have also had great luck with accuracy and they are absolutely devastating on game.....just flattens deer.  I am sure a 130 or 140 would do the same, but old habits are hard to change. 

Thanks for the tip on spinning the case, I will try that.  I'm OK with it taking more time....reloading is very therapeutic to me.

I had the same thing happening in my .270. And I will tell you what my problem was. Not saying this is your problem but this is what happened to me. I had a bushnell scope on mine. At ranges out to 500 yards I used to shoot great groups. Touching bullets at 100 yards to 4.5 inch groups at 500. Then I took a couple trips in really cold temps and the scope was never the same. At 100 I would still get groups touching at 100. But at 300 yards I couldn't even hit a pie plate size target. Got a Leopoldo vx2 4 by 12 power and am now shooting less than 3 inch groups at 300. My issue was a bad scope.

OK....you all talked me into it.  I worked up three loads using Barnes TTSX 130 grain bullets.  I am staying with the H4350 (55, 54, 53 grains)  I also worked up another load with the 150 grain partitions just give them one last shot (pun intended). 

A question I have concerning the banded bullets like the TTSX....When seating them, is it better to have all bands hidden under the rim of the case?  I seated them a little deeper than usual (still w/in spec) so the bands would not be showing. 

When seating bullets and determining depth or OAL....what method do you use?

If your not shooting g through a chronograph reloading is almost a waste of time. If you don't know what kind of constantcey your getting in your velocity you really have no idea how good of a load your developing. Get a load with minamal ES and grouping at 100 and you should be able to take to any range your skill set will allow

I have a chrono, maybe I should use it more.  I guess I am unsure why my velocity would change much when I am measuring each charge. 

When I try these loads I will shoot them all through the chrono to see what my velocities are.  I will report back with data, pics, etc. following this outing.  Should be able to make to the range later this week.

[longwalker]

A lot of things can affetct spread on velocity. The weight of the charge being consistent doesn't equate to consistent velocity per say. I would say it's one of the single most important aspects of reloading to study and understand

First thing you will need is a way to measure where the rifling starts. You can but a tool for this or make one like I did. To build one you will need a 1/4"x20 bolt about 3-4" long, peace of brass and proper drill bit and tap.  Drill out the primer hole and thread it. Then seat your bullet in the case just a little less than normally seated. Thèn chamber it and eject.  Look for rifling marks on the bullet( coloring the bullet with a sharpie will help) if no rifling marks then run the bolt in and push the bullet out more. Then remove blot and re-chamber and check again. Keep doing this till you find the rifling.  I like to start my load development "Jamed" .010" in the rifling if that aol will fit in my magazine. If not you at least know where your rifling starts.  If that aol won't fit the mag then you will need to start just under mag length and work in from there .  Once I determine my starting aol I do my load development. Then once if decided on powder charge I start playing with seating depth. Loads groups or 3-5 of the first aol and then .020" increments seating deeper till you find a good aol that that particular rifle likes.   Hope that all makes sense

Makes sense and I have used this method.  I have never used the sharpie method and have found it real hard to decipher rifling marks sometime.  I will have to use the sharpie trick!!  Thanks.

Dark green or black worked best for me

Another thing that works excellent for determining COL and proper bullet seating depth is what I use, old school typewriter correction fluid, AKA "Whiteout".

Tag, curious to know how the new loads did in the 270.

[jrebel]

OK....So here is some data and pictures to go along with it.  I loaded up 5 different loads (new) and another trial of the original that was giving me fits.  Today was the 100 yard range only.  These are the results of the best loads and groups.

Load #1: 

Powder: H4350 50 grains
Bullet:  Nosler Partition 150 grain 
Velocity per shot
1.  2665
2.  2655
3.  2665
4.  2606
5.  2650
Average:  2648.2 ft/sec

First shot was cold / clean bore, also first shot of the day.  Take away the first shot and you have .60 outside edge group or .40 group center measurement.  (I am not sure how they officially measure groups.  Either one is excellent.
