bullet tip
It was a pretty dismal match for me at Lodi this past weekend mostly in part to bullet issuses.....I think.
Shiloh LR express 32in 1-18, 45-90, JBA brass, swiss 1.5f, .060 poly, 210m, DDPP bullet .443/.451 (minor/major dia) 1.435 long, .002 paper.
I was told my bullets were coming in, "not straight", not that they were tumbling but, like they were getting ready to. This was at 900yd, I also had the same issue at 1000yd. I had no control over the bullet with sight movements. Is there something I should look at first?? I did look at my barrel and all seems well. I did clean it very well after getting home and found nothing out of the ordinary. We did not shoot a 800yd do to weather.
any thoughts????\
thanks, matt

Bpcrshooter,
What kind of velocity are you getting with that load?

Re: bullet tip
1.42 is about as long as an 18 twist 45 will handle beyond 800 yards. Especially if there’s a crosswind to deal with

We defiantly had cross wind! along with tail wind. It shot very well in my 45-100 but, maybe there was enough velocity to keep it stable?

Re: bullet tip
Probably need a bit more velocity. How much powder? Most successful 45-90 shooters are running around 84 grs.
Honestly 200 yards is just a good start point, 600 and 800 usually tell the tale.

Did you take a look at the crown at the muzzle?

Re: bullet tip
Yes, looks factory fresh. I even pulled the forearm off at the match to see if that was a problem...

Re: bullet tip
Next Guess.................are you certain that you are resting the barrel on the null point?

Re: bullet tip
to the best of my knowledge yes. I used a rawhide mallet to feel for it.
So what im going to do is make a chamber cast, and check things out in the chamber. then load up a few to shoot again at 900yd. I do have a few old GG molds laying around too, so I will cast a few of those up just to see what happens.

Re: bullet tip
IMHO, bullet too long for that twist rate in those conditions at that range. Wind induced yaw coming with rotational decay. Might want to go to a slightly shorter bullet in that loading/rifle combination.

Re: bullet tip
Went out Monday, had winds 11-22mph switching from tail to straight from my left. I set up at 900yd at proceeded to shoot at a man sillywet. I used exactly the same load I was using and held the steel just fine. Over the previous weekend I chucked up some bullets in the lathe and shortened them .030 and .040, I loaded those up and they shot well, maybe a bit better. So I am looking at shortening my mold (slowly!) til I get the best bullet I can for windy conditions. I have also fireformed some Starline brass and when thats clean an dry I will see how much more powder I can get in there so maybe a complete brass change from Jamison will be in my future.

Re: bullet tip
Got to the range yesterday. Load again was 87.5gr of 1.5F swiss.

First shot was a bit high but thats to be expected as it had a oiled bore but the rest fell in place.matt
