Feeding of no-taper cases

That is good news. Now if I can just find the time to get polishing! I will report back on how succesfull that turns out to be.

I have a .25X.307 (rimmed version of the .308) in an AI configuration. This came from Chase Mountain Custom. The cartridge was called the 250 Brady, there were a few built for the Encore platform back when Mike Bellm had an active forum. I put a Noveski polygonal rifled barrel on a "stub" a donor lug that was drilled out and tapped to accept the new barrel.

I have had really good performance with it. 120 gr. bullets do a job on our TN white tails!

Parent cartidge, fireformed case and .243 for comparison.

What velocities and have you tried the 115 Bergers yet?

Most important from an AI mag perspective - what OAL do end up with?

100 gr. Barns TSX, COL 2.691" 3420 fps.
120 gr. Sierra Gameking, COL 2.65" 3015 fps.

IMR 4350 for both bullets.

Vel. measured with chronograph 14' from muzzle.

Similar results for the Roberts AI which continues to please. I think I can get more out of the 115s than I have at the moment as they are very consistent performers on targets.

Still have to try them on game.

Hell, I might just do real wild and do a 257 Souper improved :D

Problem is my little 243 still shoots great and with three small kids and a busy work life it may take me years to burn out that barrel that everybody told me I would fry shooting these little atom bombs out of my 243!

I have owned two 25 souper Rifles in my time, still own one, a friend of mine, has improved one as well,.. He states that if he had his time again, he wouldnt improve it, due to pressure problems, stretching brass ect. the Souper is an awesomely accurate cartridge, !00 grainers at 3050 f.p.s grouping at less than half M.O.A is esily achieveable,..My rifle, a rebarreled Weatherby .243,..and a Timney Trigger fitted,..which has a 1Lb 4oz trigger pull,..A.D.I 2209 powder, and sierra gameking projectiles,...Love it to bits,..

Gents,

My own .250/3000 AI high grade project is two years off...that's when the custom 'smith can start. One thing full custom rifles will teach you is...patience.

In the meantime I'm going to fit a 250/3000 AI tube to a short action and "play".

Primary bullet is going to be JLK's 108 gr VLD in a match grade tube. Anyone have any experience with those?

It seems the quarter-bore clan is a small, but dedicated group. From all I can see the rest of the world is just missing out.

I like the .25/06, but it's just a little bit to much for my use. Besides, I LIKE playing with wildcats...;-)

All the best,

Wes
