Hi!

I've got this old cast bullet mold from IDEAL off ebay and i was looking to do some lights loads to plink at the range with 30 cal mausers and enfields. I've sized one batch of these 311276 with a lubrisizer at 0,311'' for the 30-06 and at 0.314'' for the 303 but the metal displaced forward of the bullet seems uneven and the groups were somewhat large at 50Y (2''+) using 7gr of bullseye. This plain based mold gives me a 168gr bullet with an alloy that can also be too hard for this purpose.

More testing will be done using lee sizing dies.

I don't have the speed of these for now but i think i'm not slow enough to get good results.

Can someone share experience with these light loads using bullseye
 
Hi!

Should i have called this one ''dear ganderite''!! haha! The main reason is that i have bullseye on hands and i want to use it. Green dot and unique would be the key? I don't have red dot on hands...
 
Have you tried not sizing your bullets?

There's a lot more you can do with Bullseye in the 303 Brit and 30-06 and all it will cost you is about $0.10 a shot (primer, powder and lead):

- don't believe the "Size to 0.001 over groove size rule". With lead bullets, don't size unless bullet diameter creates a problem with neck clearance (you want at least 0.002");
- try a softer alloy. Wheelweight is rarely too hard, and won't be too soft; and
- 7.0 grs of Bullseye is a very mild load, it's even only mid-range in both the 303 and 30-06 with a plain-base bullet. Try in the 6.0-8.0 range and use a chronograph for future reference (Bullseye is a good powder for subsonic loads). You don't want to drop below about 750 fps for fear of a bullet not exiting the bore, and won't want to exceed about 1100 fps to avoid leading the bore. You can go higher than 9.0 grs and still be well under pressure for the firearm, but with a plain-base bullet, the appearance of leading is what will stop you.
