At least it will be bad news for the targets I turn this rifle on. I have been working with the NULA 50 cal. for 4 range sessions and it went well today. It is suprising what difference a sabot will make. I switched from mmp sabots to harvester short black after reading on this board that the harvesters were tougher. I also am shooting a Dougles barrel that is very smooth and as per this board smoother barrels like powder so I went to 44 grains of VVN-110 with the 250 HXTP and it went into 5/8ths at 100 yards. Then I tried 45 grains of 4759 and it went into just under 3/4s. Now I am a happy camper because the best before this was 1.5 to 2 inch groups at 100. My son saw the groups and said " That is bad news for the deer." So the new rifle is the "Bad News Nula."

Glad to hear you got the right fit with the Harvester sabot and now with those results it's time to spread the bad news. ;D

Dans, thanks for the update, have been playing with harvesters and MMP in my .50 and have not had a blown sabot in six hours of shooting yesterday RL 7 and IMR422, groups are getting better 3" is common for the Remmington conversion. Need to get some VV110 powder and bite the Haz-mat charge?
Think I have a problem with primer ignition so I am going to turn the shoulder on the barrel to get the primer closer to the powder? 300 grain rem loads are still the only MOA load that will work, hope my thinking is right, extra weight is making the powder do a better burn?

spoonover,
IMR4227 is hard to ignite and prone to misfires in the Savage. It was one of the first powders recommended by Savage but too many misfires caused them to remove it. Not sure if the NULA primer system is the same but Id work with other powders if I was you. Mike

300 grain bullets are more reliable than anything lighter when shooting 4227. A tight sabot fit helps also. If you are going to bite the bullet and pay a hazmat charge. Get several powders to try. VVN-110, IMr-4759 and 5744. One of these three should work for you. There are numerous powders that will work. Have you looked in the archives on this board to see if you have some on hand? Reloader 10X is a very good powder with 300 grain bullets, as is 4198, 2015 and 322. I personally have had the best luck with 4759 and VVN-110 in that order so much so that I bought an 8 pound jug of 4759. Your Remmy .458 300 grain bullet is a good one and will do the trick. Have you tried Hornady XTPs the non magnum kind? They work pretty well in most rifles.

Danns, VVN-110, IMr-4759 and 5744 both Cabelas and Bass Pro seem to be out of powders, it was luck that I found the IMR 4227 and the Reloader 7. Book load powders are on the slim pickens side. Glad I looked on here before I put the barrel in the lathe, I was getting ready to set the shoulder back .03 thousandths tonight in hopes for a better burn. Thanks for the heads up on the wrong powder. Reloader 7 was getting 3'' groups with the 250's so after 5 hours of shooting I am done with both powders.
The primer is a 308 win case that fits the bolt face, the recoil lug is 1/4 '' thick so I have a longer case putting the primer farther from the powder, if more misfires occur there will be a trip to the old lathe.
