Hawkins Posted May 27, 2015 Share Posted May 27, 2015 Hi, new to the forum, first post here. My Nova Tactical can almost fit five 2.75" shells in the standard magazine, to the point where it seems that clipping a couple of coils off the recoil spring might let the fifth one in. Has anyone tried this, to see if it affects reliability? Or any idea why they didn't make the mag tube just a fraction longer? Thanks!

black_dog Posted May 27, 2015 Share Posted May 27, 2015 I wouldn't mess with the spring. Try different ammo, there are slight variations between brands/loads and they are not all an equal length. Post what ammo you are using that won't fit 5 in the tube - some other members may be able to offer more insight if they know the ammo.

Hawkins Posted May 27, 2015 Author Share Posted May 27, 2015 You're exactly right about the different lengths. I've tried Federal Premium 00 buck, generic Remington slugs, and Winchester PDX1. Federals are the longest, Winchesters the shortest--the fifth Winchester is only shy about the thickness of the rim. Even if a fifth shell would fit, though, I wondered about maybe binding the spring or leaving it that compressed for a long time. Quote Link to comment Share on other sites More sharing options...
benelliwerkes Posted May 27, 2015 Share Posted May 27, 2015 A small difference in cartridge length x 4-5 shells ,or more, is usually the source for mismatch of mfg. stated magazine capacity and being short changed one cartridge capacity.

Hawkins Posted May 28, 2015 Author Share Posted May 28, 2015 Thanks, great pictures. Actually, 4 is the stated capacity for the Nova. It was just so close to getting 5 that I wondered if there were some simple mods that would let 5 in, or if I was missing something. Quote Link to comment Share on other sites More sharing options...
benelliwerkes Posted May 29, 2015 Share Posted May 29, 2015 (edited) The 2-3/4" specification is the maximum length allowed for the fired cartridge, i.e. with the crimped petals opened up. That specification keeps the opened cartridge contained within the limits of a 2-3/4" chambered barrel and the ejection port dimension is similarly designed to eject the opened up 2-3/4" cartridge. So the length of the unfired cartridge is otherwise irrelevant. If you want to increase capacity, use the shortest shells!

HMLA-167 Warrior Posted May 31, 2015 Share Posted May 31, 2015 Ha ha. The case of that centurion shell is almost as short as the head. It doesn't even reach the the ball detent. Quote Link to comment Share on other sites More sharing options...
Shingomatic Posted November 24, 2015 Share Posted November 24, 2015 Rather than modify the factory components, get an after-market magazine extension tube with spring. I just got a +2 Nordic extension tube for my 4+1 Benelli Nova Tactical. Now my capacity is 6+1 (one in the breech). Works like a charm.
