I'm also watching this thread, as I re-barrel this caliber in 2 hunting rifles i the last year. Because of limited components, like powder only IMR 4831 was available and my old stock of RL26, I used the Hornady 154 SST for range shooting and the IMR 4831. The first chamber were a saami...

Here in Canada som RWS ammo have come in lately, so perhaps also in the US. They load with a 92gn, and 126gn bullet, Voere chamber barrels for both calibers, but the 8mm is most common, I did shoot this in a Blaser R8. Yes I think you can neck down easily, as the 8mm is likely the most common here.

I tried the RL19 in my .270win this past fall. Using the 150gn NP and RL19 55.8gn, OAL 3.340, new Hornady brass. cci 250 primers. Vo 2796-2805 ft/s. With good accuracy. The chamber somewhat oversized and some erosion in the throat after 4000-5000 shots. In case of tight chamber start 2-3gn...

My Teslong borescope shows some severe cracks across the lance, and reading here I identify them as "heat cracks". This barrel is from a 7 mm Blaser with 1000-1200 shots through (poor shooter) If this is heat cracks and deterioration of a barrel, do any one know how to prevent this in a new...

Just happen to see this thread is still active. I'm now into my 4th year experience and a 4th chambering. My experience is somewhat different direction than most here. My goal simply was to replace a 7x61SH with a non belted cartridge to give me same performance using the 160 gr. NP hunting...

I checked the reamer print against PTG and they are the same, as both are the CIP standard. One thing you might like to check is the the distance between the barrel lands Z. CIP 7.04 mm/0.2772 (JGS 6.88 mm/0.2710") Total Lead+Throat CIP 9.26 mm/0.3646", JGS calculation using the "tighter"...

I recently got a 7 mm Blaser CIP reamer from PTG, I think they do have them in stock and can ship without delay, but as Predator 22 mention I also had my share of grief dealing with PTG, mainly communication. Next time I need reamer I will try Dave Mason. Gunnar

Midnight, I just caught on to this thread today and read with interest. I did have a 7 mm Blaser made up 3 years ago, it was to replace a 7x61 so used the S&L action M65. Dies at that time was available from CH, I also bought a Body die so I could use it with the CH neck Bushing die. The...

I have a 6.5-284Norma in a savage, I have dies from Redding marked Norma, and a Forster die without Norma marked. I use the body dies from Redding and neck bushing die from Forster and seems to work very well. Some time ago a salesman saying the two is not compatible. If the chamber on the...

The 7 mm Blaser is suppose to fit on a magnum bolt face as the rim is slight rebate, I'm not sure where the problem is, first I thought a none aligned/over sized chamber. The chamber size is slight under max tolerance, Perhaps a chamber reamer with close to min. dimension would have done the...

I my self looked hard at the 7 lrm, but final decided on a 7 mm Blaser, both give the same ballistic as the 7x61, and I used the same S&L M65. My purpose was to duplicate the 7x61 but without the belt. The bolt face needed to be enlarged for the Blaser cartridge, which I do not think is...
