Hi, I`m waiting for my new to me #1 International in 7 mm Mauser to arrive. I need some bullet wt. info. What is a good bullet wt. for punching paper at 100 yds & 200 yds? Thanks in advance.

I think 140 Ballistic tips shot good, 150 not too bad. (good as far a No1's go, I would call <MOA great) The first load of 175 RN hornady's were disappointing, but I have a bunch of them so I should work up a functional load.

or stick with the 140's

shoot good

Mine is an older 1a, one of the early red pad models. It does not shoot any of the shorter bullets well, but the 175 gr round nose is fine.

I'm shooting Hornady 154's with moderate success. I have learned that the throat of 7x57 is one long empty space. So, I have these bullets seated out as far as I can get them.

Yes, seating out the lighter bullets is the way to go. These older military calibers (6.5x55 also comes to mind) were designed with long, heavy for caliber bullets. So as we have gone to lighter bullets as a mater of practice, it leaves a long jump. It’s a great caliber that used those long heavy high sectional density bullets and deep penetration to build its reputation. There is a reason Karamojo Bell used this caliber to kill hundreds of elephants (please don’t try) after the 6.5mm bullets would bend in the middle and not track straight. Funny thing about sectional density, the greater the diameter the shorter the bullet relatively, so while the 6.5’s would bend due to too long/thin hitting the elephants skull, the 7mm had no such trouble. Sorry for the tangent and I took it a long way from the original post. Please get us back on topic.

I don't know about the #1 but my 1895 Chilean likes 140 gn. bullets. :)

#1 in 7mm

My No.1 shoots OK with 140 Noslers but I thought it should shoot better. Found out how long the throat is last night. Tried seating some Barnes 140 TTSX bullets out to contact the rifling and then seat them about .050 off the rifling as suggested by Barnes. Seated a bullet up to the first groove and put it in the gun, the action closed!. So, started over, put a 150gr. Barnes TTSX in the case and seated it just past the boattail so it would stay in the case and tried it. Action didn't close but it wasn't far off. OAL to close was actually 3.361" No wonder it doesn't shoot well with standard seating recommendations. I seated it .045 deeper to see if Barnes was right. May have to add some powder with all the empty space in the case.

I’m sorry, your post makes little sense to me, if you’re .050 OTL there Is no reason why it won’t close., because you’re not ITL

I suggest you load 5 st .010”, from there go to .050”, then .090”, then .130”, all OTL. Shoot those and I promise one of those groups will out shine the rest. From there you refine, (break down) that group into smaller seating depth adjustments, It won’t take long and you’ll have it shooting how you want it to.

I run my 7-08 .075” over SAAMI specs, (2.875”) it was a long process, but I’ll shoot my pistol against any rifle. Win or lose, I’ll give them a good run.

I need to get my #1 out again and mess with it. It's been a couple years. I got frustrated with it because I couldn't get it to shoot quite as well as I thought it should. I suspect it has a long throat in it as well. The one round it seemed to like was by S&B seems like it was around 170gr. 140 grain were disappointing. But then again, maybe it was the operator.

My 7x57 is a Ruger model 1AB and I've had excellent results with 140 gr Sierra bullets and the 139 gr Hornady SST. If I were to try a heavier bullet I believe I would start with the Hornady 154 SST.

Very nice Mauser there. Usually they're beat to he!! but yours looks in very good condition. My Chilean also like 140 grain and heavier. It's been sporterized some time in the earthy 70s into a Mannlicher with 20" barrel. I picked it up in a Clovis New Mexico gun shop in 1972 for the princely sum of $60. Still use it today.

Do you have any pics of your sportized mauser?
