Bullet Barn 200gr gc .303 OAL?

As long as it fits in the magazine you should be good!
I normally run somewhere around a caliber width of depth into the neck for starters.......

I'll give that a try. I've never used these before, only tapered match bullets or even hunting bullets. The profile on these is different.
I was noticing that the bolt handle was getting stiff in the last bit of closing, and figured I was seating them too long.

Your No 4 Mk 2 has probably not suffered the throat erosion that my older rifles have. Load a dummy round long and close the bolt on it. That will tell you your OAL. Theoretically, if it fits in the mag it will chamber in the gun.
I tried that and couldn't see the marks where it touched, just felt the resistance with the last bit of bolt turndown. I've had no trouble seeing such marks with new jacketed bullets, but these lead ones were not showing any signs I could see. Frustrating.
I can't answer that, because I don't have a chrony, haven't loaded any of them yet, and my plan is to use Ganderite's suggestion of a reduced load using Unique.
I'm moving to reduced loads because I'm only punching paper or gongs, and I want less stress on my shoulder, my brass, and my budget.
Hopefully someone else here can answer your question.

I was debating on 174 175 grain vs a 200 grain for a number 1 Mark 3 anyone got advice??
If they aren't gas checked, the heavier bullet allows you to get some more pressure for a better powder burn while still staying at lower velocities in the 1500 fps range.
If it's gas checked you can push them faster and get the pressure up. Can get close to 2000fps using 4198 or or similar powder.
Have you checked your bore? Some of the MKI have oversize bores and chambers. I have a No1 MKIII that needs a .314" or larger cast bullet to stop key-holing at 50 yds.

I checked the .310 Hornady ones I have here and both my mark 1 and no4 that's sporterized are tight, so it's good, I throat checked by putting a bullet into the end, and it never went in the muzzle too far, maybe 4 or 5 mm, I shot ppu 174 grains and some Winchester 180 grain pp, and perfect
I have used cast in several rifles. Always got the best results with the heavy round nose bullet.

I was shooting 200 gr cast Bullet Barn bullets with 38 grns of 4895. Accuracy wasn't great at 100 yards but I did manage a 3" group. Ladder test with 4895, 36 grns to 40. I intend to do some more research as I only got to shoot that load in one #4 rifle. I want to see how it does in an old No. 1.
The largest diameter cast bullet you can chamber cleanly is usually the most accurate. Some chambers/throats on the Lee Enfield rifles are on the larger side and a wider diameter bullet stays centred better and tends to enter the rifling straighter and more concentric with the bore. Jacketed bullets have the same issue to some degree but it is more pronounced in cast bullets.

What load are you using? I never had any better luck with 4350 over 4895.
