Nigel - Interesting re GGG that is good to know.
Strangely Brown - That sounds potentially great I will message you.
The L42A1 is not a new designed rifle it is an upgrade of a No4 Mk1 to provide a sniper rifle using the then current NATO 7.62 round. Those that use heavier projectiles are pushing the limits of the action. The 144 was used by target rifle shooters out to 1,000yds.

Thanks Bindi2,
I appreciate it is t a modern rifle and being based on WW2 No.4(t) rifles it was certainly not designed for the heavier newer rounds, I just hadn’t appreciated it was as light as the 144. Thanks for the information.

303 barrels were built for 173gr flat bottom bullets, they work fine with lighter bullets depending on your loads, wear, etc.
7,62 barrels built for boat tail 145gr bullets, but again will work with heavier and other bullets, again depending on what you load.

Its not the barrel that's the problem it is the action. You can load anything into a case and fire it. Later day 7.62/308 have a higher pressure than what the action was built for,

I had to build a new bolt for a guy out west last year because he blew it up with a hot handload and heavy, (I think 175 grain projectile). Remarkably, the body wasn't damaged at all. I have a close friend who's the most knowledgeable precision rifle shooter I know and he's had great success with 155 and 168 grain SMK projectiles. It's all about keeping pressures and velocities at normal levels. The one thing I've noticed over the years is how well the No.4T and L42 perform with just normal old 174 grain, (.303) and 144 grain, (7.62), ball ammo. I just fired a 1.75", five shot group yesterday at 100 yards with a recently restored .303 ROFM 1941 No.4T and Mk.1 scope using the German MEN 83 Mk.7z ammo. I can't ask for much more than that considering the factory spec. was 3" groups at 100 yards! They are amazing old rifles if fitted together properly and gauge in spec..

Well in terms of the proof, it has been proofed to 20 tonnes, I am planning to keep to lighter weight lower power rounds and il see how it goes. Thanks for the information and advice!

Second the GGG - very consistent (plus pretty much problem free in straight pull FAL/L1A1s)

Second that one, GGG is a very good round.

This is very broad and general. The bullet weight is only one aspect to keep in mind. Heavier bullets don't mean higher pressure except if you load it that way. Bottom line, be aware of the details of the cartridges you are using, either commercial which are often underloaded, or military which mostly aren't. Check the first few shots to see what the empty cases tell you.

So GGG shot very well as did some 144grn Israeli defence stuff.
Picked up the “new” rifle today, before I get accused too much of being bubba the receiver if a Mk2 which had no wood or barrel but did already have scope pads, the barrel is an original L42 program barrel. The work was done by Fulton and I am pleased with the results.
