Loading problem! BORE TECH solids

[Surgeon_Shooter]

Fellas ive tried all that i know to do as far as loads with this bullet maybe yall can help. I have the bore tech 245grn v3 match in .338. My rifle is a surgeon remedy with a 28.5 krieger and it has a 1:9.5 twist rate. How far am i supposed to seat off the lands?????? I heard it was .070 but i dont know for sure. I think i have the right twist because they hit perfectly straight frow 50 to 300 yrds. Any suggestions on powder? im using retumbo and rl 25.

What is the problem? Your specs sound right but I dont know what your looking for.

Surgeon-Shooter,

I would load 3 rounds at each seating depth,starting from .070 to .010 in 10 thou increments until you see the groups tighten up.Then go in 5 thou and out 5 thou from there to see which shoots best.Seems like my ELR guns shoot good just below max pressures.A grain or so less than what load causes a sticky bolt.

Also I wouldn't try to shoot groups at less than 300 yards because the bullets might not be stabilizing correctly yet.After pulling my hair out with my 375CT,trying to develop a load with 330 Lehigh solids,I discovered that the gun shot as good at 400 yards as it did at 200Y.The bullets just were not fully stabilized at 200Y.Try to pick a calm day and don't be concerned with the horizontal too much.

After finding seating depth you should do a ladder test.That way you are reasonably assured that when August comes and it's 20 degrees warmer,your loads won't be too hot.

The only other powder I could think to suggest is US-869 but either of the 2 you have should work fine.The Retumbo probably gives the best load density but you might be losing some velocity.

Let us know what happened.Good luck.

Ok, I went out to the reloading station a minute ago and found where the bullet meets the lands. The OAL at the lands is 4.019 and I'm gonna start out @ .070 off the lands. But when I shove the bullet in to 3.949 one of the belts on the bullet is still exposed out of the brass. I don't think this will effect anything but I need your opinion. I'm new to the whole SOLID bullet thing and I'm kinda lost.

SS,

I imagine that you are loading single shot because of the OAL.If so then the belt is not an issue.

Also was .070 recommended by the manufacturer ? If not then I would start close to the lands first then work back into the case.

Re: Loading problem! BORE TECH solids

I emailed bore tech and didn't get a response but I've done some reading on some other solids and most that I found say to seat them about .070 first.
