Thr NEF Handi Rifle can be a sweetheart of a gun, but it may require some effort and TLC on the part of the shooter to get the most of it.
Some rifles, notably in .357 caliber, have been criticized for having excessively long throats; some rather hot calibers (.223, .243) have had problems with fired cases stuck in the chamber. Trigger pull is a problem in every one of 'em.
Some .357 owners have had their rifles rechambered to .357 Maximum and have had excellent results. Hand polishing AND CLEANING of the chamber has reduced the problem of sticking fired cases. And, unless things have changed, the factory will hone your trigger to an acceptable 3.5-lb. pull free of charge.
The nicest thing about the little NEF is that late manufacture models allow for interchangeability of various caliber barrels. For instance, mine has both a .45-70 and a .22 Hornet barrel. Just remove the forearm screw, break open the gun and remove the barrel. If each barrel is scoped, return to zero is no problem when barrels are swapped.
With the .45-70 I have no problem getting 1.25-inch five shot groups at 100 yards. The Hornets gets as low as .75 under windless conditions.
