No4Mk1 accuracy

[303carbine]

Over the past two days I have been testing the No4 again, I applied the bedding as per Mr. Laidlers instructions.
I tested the rifle with the same rest, same ammo , same distance, same target on two consecutive days.
First off with the bedded rifle, I shot a dismal four inch group at 55 yds with 174 grain Hornady's over 37 grains of IMR 3031.
Next day with the bedding removed and barrel tip free floated, same target etc., I shot another four shot group, I shot a triangular group that measured
1& 1/4 inch x 1 & 1/4 inch x 3/8ths inch with two bullets touching.
I guess my rifle just doesn't like the bedding at the tip.
