1:28, 30,32 twist..anyone using conicals
 

I've tried some conicals with CVA Optima with 1:28 twist. Im using open sights (peep)Did ok up to 50 yds but started going terrible at 75 so no need testing 100. Used 70 & 80 grains of BH209, Black MZ and T7 with 437 gr conical. Anyone have a particular rifle with 1:28, 1:30, 1:32 using 400 to 450 gr conicals that shoots good?

Are you using any wads under the conical?

maybe it just doesnt like your conical. They all shoot differently and some just simply may not like that bullet design.

Try a 385gr hornady great plains bullet.

I have a 1:32, and I am getting a 1:32 built just for conicals . 425 gr up to 750 gr shoot good in a 1:32. My 1:32 shoots the 425 with 90 gr powder but it’s a .54
The one I am having built is a .54 also and it’s patterned after the White Grand Alaskan which is a 1:32 and can handle a 750 gr conical with 200 gr powder if you ever go elephant hunting :)

I have several Fast Twist barrels from .45 to .54 Cal that shoot lights out good with Conicals, Paper Patched and Grease Groove, My fast twist barrels range from 1:18 to 1:32 twist, What conical are you shooting? I have 1 rifle that is finicky, it is a Stainless Green Mountain LRH .50 Caliber, this particular rifle will not shoot a Pure lead bullet worth a darn, But when i bump the Lead hardness up to 8 Brinell, and all the way up to 15 Brinell This rifle comes alive! All of my other rifles will shoot soft lead, or slightly hardened equally well. Something about the Stainless? My friend Idahoron has experienced the same thing with his Stainless Green Mountain barrels (Ron runs between 8-9 Brinell Hardness with his Alloy) I am not familiar with your particular rifle, is it a Stainless barrel? If so, Maybe it needs a slightly harder bullet like ours in order to perform well? Also, I absolutely swear by using Wool felt for an Over Powder Wad with any Grease Groove bullet, In my testing, my results were never that great with Hard Card (.060 Vege Fibre) and Grease Groove bullets, Wool felt under the GG bullet base has been the clear winner for me, I seat a Hard Card (.060 Vege Fibre) on the powder, then a wool felt on top of the Hard Card, And seat my bullet. The Hard Card might not be needed? But sure hasn’t hurt anything in all of my testing. I feel the most important part is having the Grease Groove bullet on top of a Wool felt Wad.

I thought Doc White's 54s were 1-28.

I only seen one grand Alaskan and I am pretty sure it was a 1:32. Maybe we should ask if any other DWB knows for sure. Could confirm with Doc but sometimes it takes a while to hear back from him . The Grand Alaskan was basically a 54 cal super 91 with a heavy barrel. I remember Doc talking about how accurate it was with 750 gr conical and 200 gr powder if you want a gun for African hunt .

Here’s a .54 Cal Slug for the White Rifle you speak of, the 1 on the left weighs 650 Grains

I love the one on the far left, reminds me of the FP powerbelts. No grease grooves I noticed. Is this paper patched?

Yea they are both PP for .54 Cal, they Drop from the mold at .533 and wrap up to .540-.541, That one on the left is 650 Grains, She kicks the Pee outa ya! :eek:
