I am having a devil of a time getting my solids to impact anywhere near my softs at even 25 yards! Suggestions would be appreciated.

I am shooting a Win 70, with Leupold 2.5 x 8 and each load groups well, but with a very different point of aim.

I am loading 300 grain Barnes TSX with 76.0 grains of IMR 4350. This shoots very well in this rifle, at about 2450 fps over my Oehler Chrony. I am trying to work up a load shooting Barnes banded solids (300 grain also). With the same powder charge, these bullets strike 3 inches low and 3 inches left at 25 yards. At 100 yards they are off the paper! I have adjusted the poweder charge down a couple grains, without any change. At 76.0 grains, the solids are doing 2500 fps over the chrony, so a bit faster than the TSX, but not much. Reducing the charge weight to get the same velocity doesn't appreciably effect point of impact.

What's going on here! Any thoughts?

Thanks,

Bill

I purchased some North Fork 300gr softs and some 300 gr cup points and 5 solids to try.
I loaded 71 gr RX 15 and all shoot to the same poi in my CZ 375 with Brockaman stock.
Spoke with Mike at North Fork, Mike said I might have to drop a grain with the solids, but I did not.

If you are going to hunt buff, you should look seriously at the North Forks.

Shot buff, it penetrated from chest straight on to back of stomach and retained 285 gr weight with picture perfect mushroom.

Using this soft, you don't have to worry about hitting another animal behind the one you are shooting.

The velocity was over 2600 fps and sub 1/2" accuracy

I couldn't get the Barnes 300 grain banded solids to shoot groups in my 375 at all.

The 300 grain TSX will do 1/2" if I do my part and the smallest groups that I could get out of the banded solids would be 3" at 100 yards on their best day. Mine also hit left of center for just about every powder charge.

My results were the same a Fjold's in my .375. I have a few boxes left of the oooold Hornady 300gr steel-jacketed solids that I got to shoot to the same point of aim, but with a slight powder change.

It is a trial and error process. But the closer the bullet shapes are to each other the better your chances will be. Sometimes you will just luck out though.
Take care,

I would honestly try a different set of bullets.



I had no trouble regulating my 450 Dakota with North Fork bonded soft points, Cup Point solids and FN solids.

If your rifle will feed the Barnes FN it should handle the North Fork.

Or you could keep the Barnes FN Solid and try the North Fork bonded SP. They also co-located in my rifle.

Let us know how it goes.

I second the idea of North Fork bullets. Great bullets great accuracy in my - one rifle - experience.

I have had problems with the Barnes triple x and the solids shooting well together I use the Swift softs and the TBS's they shoot within an inch of each other @100yds, using 68g R-15.

I worked up loads for my buddies rifle which is the exact combo you have. I like 4350 and got great accuracy out of it, but had the same problem you have. We ended up using 71.0 gr. of Reloder 15 with the 300 Swift softs and the Barnes 300 banded solid. Rem cases and Win mag primers. Both shot to the same P.O.A, both chrono'd close to 2550 fps on 86-90* days. He killed two Buff, the first one dropped dead at the first shot, frontal chest, Swift soft. The second got two and piled up within 50 yds. One shot kill with the Swift on a Zebra @50yds and it only ran about 40 and piled up with no heart left and a broken shoulder where the bullet exited. Hartebeast basically the same. I'm not trying to sell you on the Swifts, but this load with those two bullets really came together for us. Good Luck! Lee.

I had good luck getting the Northfork 300 Gr. soft point and Barnes solids (old style RN not banded) to shoot very close together at 100 yds. I used 78 Grs. of H4350. Hope this helps.

It used to be that we were not supposed to mix X bullets with other types because of fouling with a mix of materials and the erratic results that would be caused.

Is that still the rule with Triple shock bullets?

I appreciate the suggestions. I've been doing a bit more testing, and while still not there, things are looking more promising.

I have had very little fouling with this 375 using either the Barnes TSX or banded solids. the same for TBBC and other reloads I have put together.

The issue isn't accuracy with the banded solids. They shoot very well, just to a dramatically different point of impact compared to the TSX bullets. I loaded some 300 gr. banded solids with both IMR 4350 (75.0 + 76.0), and RL-15 (68 + 69 + 70). 2 shots with each charge weight, and the resulting 10 shot group measured a mere 1 1/2" at 100 yards. To say I was surprised is an understatement. The group was no where near the point of impact for the TSX's, but I have decided to play with that load instead. I really liked the RL-15 load with the banded solids. Consistent velocity shot to shot, and steadily increasing with charge weight. These 6 shots were all in an inch. If a load is that forgiving, I am definitely interested!

I'll keep playing and let you know what else I find out.
Thanks,

A guy named Kole Conley from Conley Precision Cartrideg Co. loaded some .375 H&H's for me and a friend of mine. They were Barnes 300gr TSX & 300gr Banded solids. We shot them out of Win. model 70's that we both bought new in 2004. Both of those rifles would shoot less than 1 1/2" at 100 with either bullet and put them in the exact same place.

Don't know the powder type or charge. He has a website and you can contact him from it. We each killed buff with ours.

If you're finding the POI difference has a horizontal component, you have barrel resonance issues. Free float the barrel through the handguard. If that doesn't help, bed the action (not the barrel).

Normally, the horizontal component of a POI shift between loads is a few inches at most. What you are describing indicates something is not ideal with the gun in question.

Just my opinion.

Another variable to play around with is seating depth of the TSX. I was having similar problems getting banded solids and TSX's together (6 inch or so vertical). Reducing the seating depth helped a lot. Hadn't completely finished getting it where I wanted it, and now our range is closed because of rezoning.
